BASIS OF PRESENTATION

Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements of Eaton Corporation plc (Eaton or the Company) have been prepared in accordance with generally accepted accounting principles for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by United States generally accepted accounting principles (US GAAP) for complete financial statements. However, in the opinion of management, all adjustments (consisting of normal recurring accruals) have been made that are necessary for a fair presentation of the condensed consolidated financial statements for the interim periods. This Form 10-Q should be read in conjunction with the consolidated financial statements and related notes included in Eaton’s 2019 Form 10-K. The interim period results are not necessarily indicative of the results to be expected for the full year. Management has evaluated subsequent events through the date this Form 10-Q was filed with the Securities and Exchange Commission. During the first quarter of 2020, Eaton re-segmented certain reportable operating segments due to a reorganization of the Company's businesses. The new reportable segments are Electrical Americas and Electrical Global, which include the legacy Electrical Products and Electrical Systems and Services segments. Additionally, the Filtration and Golf Grip businesses previously included in the Hydraulics segment, and the electrical aerospace connectors business previously included in the Electrical Products segment, have been added to the Aerospace reportable segment as part of the reorganization. Previously reported financial information for these reportable segments has been updated for 2018 and 2019 in Note 13. The Company recorded $6 of net gains for the quarter ended March 31, 2019 related primarily to the remeasurement of intercompany loans denominated in a foreign currency and the currency exchange derivative contracts used to hedge these exposures. In the first quarter of 2020, Eaton changed the presentation of these gains from Other (income) expense - net to Interest expense - net, and reclassified all prior periods to conform to the current year presentation. In the first quarter of 2020, the Company also changed the presentation of the following items within the operating activities section of the Condensed Consolidated Statements of Cash Flows: • The non-cash gains and losses associated with currency exchange derivative contracts have been moved from Changes in working capital to Other-net. This puts the non-cash impact of these derivatives on the same line as the non-cash impact from the balance sheet currency exposures they are used to hedge. • The changes in uncertain tax positions have been moved from Other-net to Changes in working capital. This places the cash flow impact from all taxes on the same line. These cash flow reclassifications have been made to prior period amounts to conform to the current year presentation as follows: Three months ended March 31, 2019 Condensed Consolidated Statements of Cash Flows As originally reported As adjusted Effect of change Changes in working capital $ (306 ) $ (198 ) $ 108 Other - net 125 17 (108 ) Net cash provided by operating activities 551 551 — Adoption of New Accounting Standard

Business Combinations [Abstract]
Acquisition and Divestitures of Businesses	ACQUISITIONS AND DIVESTITURES OF BUSINESSES Acquisition of controlling interest of Ulusoy Elektrik Imalat Taahhut ve Ticaret A.S. On April 15, 2019, Eaton completed the acquisition of an 82.275% controlling interest in Ulusoy Elektrik Imalat Taahhut ve Ticaret A.S. (Ulusoy Elektrik), a leading manufacturer of electrical switchgear based in Ankara, Turkey, with a primary focus on medium-voltage solutions for industrial and utility customers. Its sales for the 12 months ended September 30, 2018 were $126 . The purchase price for the shares was $214 on a cash and debt free basis. As required by the Turkish capital markets legislation, Eaton filed an application to execute a mandatory tender offer for the remaining shares shortly after the transaction closed. During the tender offer, Eaton purchased additional shares for $33 through July 2019 to increase its ownership interest to 93.7% . Ulusoy Elektrik is reported within the Electrical Global business segment. Acquisition of Innovative Switchgear Solutions, Inc. On July 19, 2019, Eaton acquired Innovative Switchgear Solutions, Inc. (ISG), a specialty manufacturer of medium-voltage electrical equipment serving the North American utility, commercial and industrial markets. Its 2018 sales were approximately $18 . ISG is reported within the Electrical Americas business segment. Acquisition of Souriau-Sunbank Connection Technologies On December 20, 2019, Eaton acquired the Souriau-Sunbank Connection Technologies (Souriau-Sunbank) business of TransDigm Group Inc. for a cash purchase price of $906 , net of cash received. Headquartered in Versailles, France, Souriau-Sunbank is a global leader in highly engineered electrical interconnect solutions for harsh environments in the aerospace, defense, industrial, energy, and transport markets. Its sales for the 12 months ended June 30, 2019 were $363 . Souriau-Sunbank is reported within the Aerospace business segment. The acquisition of Souriau-Sunbank has been accounted for using the acquisition method of accounting which requires the assets acquired and liabilities assumed be recognized at their respective fair values on the acquisition date. The table below summarizes the preliminary estimated fair values of the assets acquired and liabilities assumed on the acquisition date, as well as measurement period adjustments recorded as of March 31, 2020. These preliminary estimates will continue to be revised during the measurement period as third-party valuations are received and finalized, further information becomes available and additional analyses are performed, and these differences could have a material impact on Eaton's preliminary purchase price allocation. The current measurement period adjustments did not have a material impact to the Consolidated Statements of Income. Preliminary Allocation Measurement Period Adjustments Adjusted Preliminary Allocation Accounts Receivables $ 60 $ — $ 60 Inventory 121 — 121 Prepaid expenses and other current assets 5 — 5 Property, plant and equipment 101 — 101 Other intangible assets 385 — 385 Other assets 8 — 8 Accounts payable (34 ) — (34 ) Other current liabilities (51 ) 1 (50 ) Other noncurrent liabilities (130 ) — (130 ) Total identifiable net assets 465 1 466 Noncontrolling interests (4 ) — (4 ) Goodwill 442 2 444 Total consideration, net of cash received $ 903 $ 3 $ 906 Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the anticipated synergies of acquiring Souriau-Sunbank. Goodwill recognized as a result of the acquisition is not deductible for tax purposes. Other intangible assets of $385 are expected to include customer relationships, trademarks and technology. Given the timing of the acquisition, Eaton utilized a benchmarking approach based on similar acquisitions to determine the preliminary fair values for intangible assets. See Note 6 for additional information about goodwill. Eaton’s 2020 Condensed Consolidated Financial Statements include Souriau-Sunbank’s results of operations. Souriau-Sunbank’s sales in the first quarter were $85 . Sale of Automotive Fluid Conveyance business On December 31, 2019, Eaton sold its Automotive Fluid Conveyance Business. The transaction resulted in a pre-tax loss of $66 which was recorded in Other expense (income) - net. This business was reported within the Vehicle business segment. Acquisition of Power Distribution, Inc. On February 25, 2020, Eaton acquired Power Distribution, Inc. a leading supplier of mission critical power distribution, static switching, and power monitoring equipment and services for data centers and industrial and commercial customers. The company is headquartered in Richmond, Virginia, and had 2019 sales of $125 . Power Distribution, Inc. is reported within the Electrical Americas business segment. Sale of Lighting business On March 2, 2020, Eaton sold its Lighting business to Signify N.V. for a cash purchase price of $1.4 billion . The Company recognized a pre-tax gain of $221 . The Lighting business, which had sales of $1.6 billion in 2019 as part of the Electrical Americas business segment, serves customers in commercial, industrial, residential, and municipal markets. Pending sale of Hydraulics business On January 21, 2020, Eaton entered into an agreement to sell its Hydraulics business to Danfoss A/S, a Danish industrial company, for $3.3 billion in cash. Eaton’s Hydraulics business is a global leader in hydraulics components, systems, and services for industrial and mobile equipment. The business had sales of $2.2 billion in 2019. The transaction is subject to customary closing conditions and regulatory approvals and is expected to close by the end of 2020. Assets and liabilities held for sale During the fourth quarter of 2019 and first quarter of 2020, the Company determined the Lighting business and Hydraulics business, respectively, met the criteria to be classified as held for sale. Therefore, assets and liabilities of these businesses have been presented as held for sale in the Consolidated Balance Sheets as of December 31, 2019 and March 31, 2020 , respectively. Assets and liabilities classified as held for sale are measured at the lower of carrying value or fair value less costs to sell. There was no write-down as fair values of both the Lighting business and Hydraulics business assets less their costs to sell exceeded their respective carrying values. Depreciation and amortization expense is not recorded for the period in which Other long-lived assets are classified as held for sale. The Company used the relative fair value method to allocate goodwill to both the Lighting and Hydraulics businesses. The fair values of the Lighting business and Hydraulics business were estimated based on a combination of the prices paid to Eaton by Signify N.V. and Danfoss A/S, respectively, and a discounted cash flow model. The model includes estimates of future cash flows, future growth rates, terminal value amounts, and the applicable weighted-average cost of capital used to discount those estimated cash flows. The weighted-average cost of capital is an estimate of the overall after-tax rate of return required by equity and debt market holders of a business enterprise. These analyses require the exercise of judgments, including judgments about appropriate discount rates, perpetual growth rates, revenue growth, and margin assumptions. The assets and liabilities classified as held for sale for the Lighting business on the December 31, 2019 Consolidated Balance Sheet and the Hydraulics business on the March 31, 2020 Consolidated Balance Sheet are as follows: March 31, 2020 December 31, 2019 (Hydraulics business) (Lighting business) Cash $ 1 $ — Accounts receivable - net 361 220 Inventory 412 161 Prepaid expenses and other current assets 3 10 Net property, plant and equipment 443 155 Goodwill 908 470 Other intangible assets 250 330 Operating lease assets 46 25 Deferred income taxes 3 — Other noncurrent assets 13 6 Assets held for sale - current $ 2,440 $ 1,377 Accounts payable $ 221 $ 184 Accrued compensation 25 7 Other current liabilities 110 102 Pension liabilities 69 3 Operating lease liabilities 30 17 Deferred income taxes 3 (1 ) Other noncurrent liabilities — 13 Liabilities held for sale - current $ 458 $ 325 The Lighting business and Hydraulics business did not meet the criteria to be classified as discontinued operations as neither of these sales represent a strategic shift that will have a major effect on the Company's operations.

REVENUE RECOGNITION

REVENUE RECOGNITION	3 Months Ended
	Mar. 31, 2020
Revenue from Contract with Customer [Abstract]
REVENUE RECOGNITION	REVENUE RECOGNITION Sales are recognized when obligations under the terms of the contract are satisfied and control of promised goods or services have transferred to our customers. Sales are measured at the amount of consideration the Company expects to be paid in exchange for these products or services. In the Electrical Americas segment, sales contracts are primarily for electrical components, industrial components, power distribution and assemblies, residential products, single and three phase power quality, wiring devices, circuit protection, utility power distribution, power reliability equipment, and services that are primarily produced and sold in North and South America. The majority of the sales in this segment contain performance obligations satisfied at a point in time either when we ship the product from our facility, or when it arrives at the customer’s facility; however, certain power distribution and power quality services are recognized over time. In the Electrical Global segment, sales contracts are primarily for electrical components, industrial components, power distribution and assemblies, single phase and three phase power quality, and services that are primarily produced and sold outside of North and South America; as well as hazardous duty electrical equipment, emergency lighting, fire detection, intrinsically safe explosion-proof instrumentation, and structural support systems that are produced and sold globally. The majority of the sales contracts in this segment contain performance obligations satisfied at a point in time either when we ship the product from our facility, or when it arrives at the customer’s facility; however, certain power distribution and power quality services are recognized over time. Many of the products and services in power distribution and power quality services meet the definition of continuous transfer of control to customers and are recognized over time. These products are engineered to a customer’s design specifications, have no alternative use to Eaton, and are controlled by the customer as evidenced by the customer’s contractual ownership of the work in process or our right to payment for work performed to date plus a reasonable margin. As control is transferring over time, sales are recognized based on the extent of progress towards completion of the obligation. Eaton generally uses an input method to determine the progress completed and sales are recorded proportionally as costs are incurred. Incurred costs represent work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. In the Hydraulics segment, sales contracts are primarily for hydraulic components and systems for industrial and mobile equipment. These sales contracts are primarily based on a customer’s purchase order. In this segment, performance obligations are generally satisfied at a point in time when we ship the product from our facility. In the Aerospace segment, sales contracts are primarily for aerospace fuel, hydraulics, and pneumatic systems for commercial and military use, as well as filtration systems for industrial applications. These sales contracts are primarily based on a customer’s purchase order, and frequently covered by terms and conditions included in a long-term agreement. In this segment, performance obligations are generally satisfied at a point in time either when we ship the product from our facility, or when it arrives at the customer’s facility. Our military contracts are primarily fixed-price contracts that are not subject to performance-based payments or progress payments from the customer. In the Vehicle segment, sales contracts are primarily for drivetrains, powertrain systems and critical components that reduce emissions and improve fuel economy, stability, performance, and safety of cars, light trucks and commercial vehicles. These sales contracts are primarily based on a customer’s purchase order or a blanket purchase order subject to firm releases, frequently covered by terms and conditions included in a master supply agreement. In this segment, performance obligations are generally satisfied at a point in time either when we ship the product from our facility, or when it arrives at the customer’s facility. In the eMobility segment, sales contracts are primarily for electronic and mechanical components and systems that improves the power management and performance of both on-road and off-road vehicles. These sales contracts are primarily based on a customer’s purchase order. In this segment, performance obligations are generally satisfied at a point in time either when we ship the product from our facility, or when it arrives at the customer’s facility. In limited circumstances, primarily in the Electrical and Vehicle segments, Eaton sells separately-priced warranties that extend the warranty coverage beyond the standard coverage offered on specific products. Sales for these separately-priced warranties are recorded based on their stand-alone selling price and are recognized as revenue over the length of the warranty period. The Company’s six operating segments and the following tables disaggregate sales by lines of businesses, geographic destination, market channel or end market. Three months ended March 31, 2020 Net sales Products Systems Total Electrical Americas $ 724 $ 1,064 $ 1,788 Electrical Global 657 487 1,144 United States Rest of World Hydraulics $ 227 $ 280 507 Original Equipment Manufacturers Aftermarket Industrial and Other Aerospace $ 325 $ 220 $ 135 680 Commercial Passenger and Light Duty Vehicle $ 292 $ 306 598 eMobility 72 Total $ 4,789 Three months ended March 31, 2019 Net sales Products Systems Total Electrical Americas $ 905 $ 1,056 $ 1,961 Electrical Global 696 546 1,242 United States Rest of World Hydraulics $ 266 $ 339 605 Original Equipment Manufacturers Aftermarket Industrial and Other Aerospace $ 290 $ 211 $ 103 604 Commercial Passenger and Light Duty Vehicle $ 431 $ 379 810 eMobility 83 Total $ 5,305 The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (revenue recognized exceeds amount billed to the customer), and deferred revenue (advance payments and billings in excess of revenue recognized). Accounts receivables from customers were $2,669 and $3,090 at March 31, 2020 and December 31, 2019 , respectively. Amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals or upon achievement of contractual milestones. These assets and liabilities are reported on the Consolidated Balance Sheets on a contract-by-contract basis at the end of each reporting period. Unbilled receivables were $96 and $101 at March 31, 2020 and December 31, 2019 , respectively, and are recorded in Prepaid expenses and other current assets. The decrease in unbilled receivables was primarily due to billings to customers during the quarter, partially offset by revenue recognized and not yet billed. Changes in the deferred revenue liabilities are as follows: Deferred Revenue Balance at January 1, 2020 $ 234 Customer deposits and billings 245 Revenue recognized in the period (240 ) Translation (4 ) Deferred revenue reclassified to held for sale (11 ) Balance at March 31, 2020 $ 224 Deferred Revenue Balance at January 1, 2019 $ 248 Customer deposits and billings 208 Revenue recognized in the period (205 ) Translation 6 Balance at March 31, 2019 $ 257 A significant portion of open orders placed with Eaton are by original equipment manufacturers or distributors. These open orders are not considered firm as they have been historically subject to releases by customers. In measuring backlog of unsatisfied or partially satisfied obligations, only the amount of orders to which customers are firmly committed are included. Using this criterion, total backlog at March 31, 2020 was approximately $5.4 billion . At March 31, 2020 , Eaton expects to recognize approximately 87%

CREDIT LOSSES FOR RECEIVABLES

CREDIT LOSSES FOR RECEIVABLES	3 Months Ended

Credit Loss [Abstract]
CREDIT LOSSES FOR RECEIVABLES	CREDIT LOSSES FOR RECEIVABLES Receivables are exposed to credit risk based on the customers’ ability to pay which is influenced by, among other factors, financial performance, geography, or lines of businesses. Eaton’s receivables are generally short-term in nature with a majority outstanding less than 90 days. Eaton performs ongoing credit evaluation of its customers and maintains sufficient allowances for potential credit losses. The Company evaluates the collectability of its receivables based on the length of time the receivable is past due, and any anticipated future write-offs based on historic experience adjusted for market conditions. The Company’s segments, supported by our global credit department, perform the credit evaluation and monitoring process to estimate and manage credit risk. The process includes an evaluation of credit losses for both the overall segment receivable and specific customer balances. The process also includes review of customer financial information and credit ratings, approval and monitoring of customer credit limits, and an assessment of market conditions. The Company may also require prepayment from customers to mitigate credit risk. Receivable balances are written off against an allowance for credit losses after a final determination of collectability has been made. Accounts receivable are net of an allowance for credit losses of $46 and $49

The Company used the relative fair value method to reallocate goodwill to the associated reporting units impacted by the reorganization. The Company’s reporting units are equivalent to the reportable operating segments, except for the Aerospace segment which has two reporting units. The fair values of the Electrical Americas and Electrical Global reportable segments were estimated based on a discounted cash flow model. The model includes estimates of future cash flows, future growth rates, terminal value amounts, and the applicable weighted-average cost of capital used to discount those estimated cash flows. The weighted-average cost of capital is an estimate of the overall after-tax rate of return required by equity and debt market holders of a business enterprise. These analyses require the exercise of judgments, including judgments about appropriate discount rates, perpetual growth rates, revenue growth, and margin assumptions. The fair value of the Hydraulics reportable segment was estimated based on a combination of the price paid to Eaton by Danfoss A/S and a discounted cash flow model. See Note 2 for additional information about the allocation of goodwill to the Hydraulics reportable segment. The Filtration and Golf Grip businesses previously included in the Hydraulics reportable segment, and the electrical aerospace connectors business previously included in the Electrical Products segment, have been added to the Aerospace segment as part of the reorganization. During the first quarter of 2020, goodwill impairment testing was performed using quantitative analyses as a result of the Hydraulics business being classified as held for sale as discussed in Note 2, and the re-segmentation of the Electrical Americas, Electrical Global and Aerospace segments. Based on these analyses performed, the fair value of Eaton's impacted reporting units continues to substantially exceed their respective carrying amounts and thus, no impairment exists. The 2020 additions to goodwill relate to the anticipated synergies of acquiring Power Distribution, Inc. The allocation of the purchase price from this acquisition is preliminary and will be completed during the measurement period.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Fair value is measured based on an exit price, representing the amount that would be received to sell an asset or paid to satisfy a liability in an orderly transaction between market participants. Fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a fair value hierarchy is established, which categorizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. A summary of financial instruments recognized at fair value, and the fair value measurements used, follows: Total Level 1 Level 2 Level 3 March 31, 2020 Cash $ 239 $ 239 $ — $ — Short-term investments 178 178 — — Net derivative contracts (206 ) — (206 ) — December 31, 2019 Cash $ 370 $ 370 $ — $ — Short-term investments 221 221 — — Net derivative contracts 53 — 53 — Eaton values its financial instruments using an industry standard market approach, in which prices and other relevant information is generated by market transactions involving identical or comparable assets or liabilities. No financial instruments were measured using unobservable inputs. Other Fair Value Measurements Long-term debt and the current portion of long-term debt had a carrying value of $8,092 and fair value of $8,383 at March 31, 2020 compared to $8,067 and $8,638 , respectively, at December 31, 2019 . The fair value of Eaton's debt instruments were estimated using prevailing market interest rates on debt with similar creditworthiness, terms and maturities, and are considered a Level 2 fair value measurement.

DERIVATIVE FINANCIAL INSTRUMENT

DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES	3 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES	DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES In the normal course of business, Eaton is exposed to certain risks related to fluctuations in interest rates, currency exchange rates and commodity prices. The Company uses various derivative and non-derivative financial instruments, primarily interest rate swaps, currency forward exchange contracts, currency swaps and, commodity contracts to manage risks from these market fluctuations. The instruments used by Eaton are straightforward, non-leveraged instruments. The counterparties to these instruments are financial institutions with strong credit ratings. Eaton maintains control over the size of positions entered into with any one counterparty and regularly monitors the credit rating of these institutions. Such instruments are not purchased and sold for trading purposes. Derivative financial instruments are accounted for at fair value and recognized as assets or liabilities in the Consolidated Balance Sheets. Accounting for the gain or loss resulting from the change in the fair value of the derivative financial instrument depends on whether it has been designated, and is effective, as part of a hedging relationship and, if so, as to the nature of the hedging activity. Eaton formally documents all relationships between derivative financial instruments accounted for as designated hedges and the hedged item, as well as its risk-management objective and strategy for undertaking the hedge transaction. This process includes linking derivative financial instruments to a recognized asset or liability, specific firm commitment, forecasted transaction, or net investment in a foreign operation. These financial instruments can be designated as: • Hedges of the change in the fair value of a recognized fixed-rate asset or liability, or the firm commitment to acquire such an asset or liability (a fair value hedge); for these hedges, the gain or loss from the derivative financial instrument, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in income during the period of change in fair value. • Hedges of the variable cash flows of a recognized variable-rate asset or liability, or the forecasted acquisition of such an asset or liability (a cash flow hedge); for these hedges, the gain or loss from the derivative financial instrument is recognized in Accumulated other comprehensive income and reclassified to income in the same period when the gain or loss on the hedged item is included in income. • Hedges of the currency exposure related to a net investment in a foreign operation (a net investment hedge); for these hedges, the gain or loss from the derivative financial instrument is recognized in Accumulated other comprehensive income and reclassified to income in the same period when the gain or loss related to the net investment in the foreign operation is included in income. The gain or loss from a derivative financial instrument designated as a hedge is classified in the same line of the Consolidated Statements of Income as the offsetting loss or gain on the hedged item. The cash flows resulting from these financial instruments are classified in operating activities on the Condensed Consolidated Statements of Cash Flows. For derivatives that are not designated as a hedge, any gain or loss is immediately recognized in income. The majority of derivatives used in this manner relate to risks resulting from assets or liabilities denominated in a foreign currency and certain commodity contracts that arise in the normal course of business. Eaton uses certain of its debt denominated in foreign currency to hedge portions of its net investments in foreign operations against foreign currency exposure (net investment hedges). Foreign currency denominated debt designated as a non-derivative net investment hedging instrument had a carrying value on an after-tax basis of $1,802 at March 31, 2020 and $1,845 at December 31, 2019 . Derivative Financial Statement Impacts The fair value of derivative financial instruments recognized in the Consolidated Balance Sheets follows: Notional amount Other current assets Other noncurrent assets Other current liabilities Other noncurrent liabilities Type of hedge Term March 31, 2020 Derivatives designated as hedges Fixed-to-floating interest rate swaps $ 2,225 $ 2 $ 123 $ — $ — Fair value 9 months to 15 years Forward starting floating-to-fixed interest rate swaps 850 — 2 — 188 Cash flow 13 to 33 years Currency exchange contracts 1,133 18 3 52 14 Cash flow 1 to 36 months Commodity contracts 15 — — 2 — Cash flow 1 to 10 months Total $ 20 $ 128 $ 54 $ 202 Derivatives not designated as hedges Currency exchange contracts $ 5,460 $ 35 $ 133 1 to 12 months Commodity contracts 4 — — 1 month Total $ 35 $ 133 December 31, 2019 Derivatives designated as hedges Fixed-to-floating interest rate swaps $ 2,225 $ — $ 57 $ — $ — Fair value 12 months to 15 years Forward starting floating-to-fixed interest rate swaps 500 — 3 — 42 Cash flow 13 to 33 years Currency exchange contracts 1,146 14 3 11 6 Cash flow 1 to 36 months Commodity contracts 9 — — — — Cash flow 1 to 9 months Total $ 14 $ 63 $ 11 $ 48 Derivatives not designated as hedges Currency exchange contracts $ 4,975 $ 48 $ 13 1 to 12 months Commodity contracts 3 — — 1 month Total $ 48 $ 13 The currency exchange contracts shown in the table above as derivatives not designated as hedges are primarily contracts entered into to manage currency volatility or exposure on intercompany receivables, payables and loans. While Eaton does not elect hedge accounting treatment for these derivatives, Eaton targets managing 100% of the intercompany balance sheet exposure to minimize the effect of currency volatility related to the movement of goods and services in the normal course of its operations. This activity represents the great majority of these currency exchange contracts. As of March 31, 2020 , the volume of outstanding commodity contracts that were entered into to hedge forecasted transactions: Commodity March 31, 2020 Term Copper 5 millions of pounds 1 to 10 months Gold 1,390 Troy ounces 1 to 6 months The following amounts were recorded on the Consolidated Balance Sheets related to fixed-to-floating interest rate swaps: Carrying amount of the hedged assets (liabilities) Cumulative amount of fair value hedging adjustment included in the carrying amount of the hedged asset (liabilities) (a) Location on Consolidated Balance Sheets March 31, 2020 December 31, 2019 March 31, 2020 December 31, 2019 Long-term debt $ (2,838 ) $ (2,838 ) $ (164 ) $ (97 ) (a) At March 31, 2020 and December 31, 2019 , these amounts include the cumulative liability amount of fair value hedging adjustments remaining for which the hedge accounting has been discontinued of $39 and $40 , respectively.

Segment Reporting [Abstract]
BUSINESS SEGMENT INFORMATION	BUSINESS SEGMENT INFORMATION Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated on a regular basis by the chief operating decision maker, or decision making group, in deciding how to allocate resources to an individual segment and in assessing performance. During the first quarter of 2020, Eaton re-segmented certain reportable operating segments due to a reorganization of the Company's businesses. The new reportable segments are Electrical Americas and Electrical Global, which include the legacy Electrical Products and Electrical Systems and Services segments. Additionally, the Filtration and Golf Grip businesses previously included in the Hydraulics segment, and the electrical aerospace connectors business previously included in the Electrical Products segment, have been added to the Aerospace reportable segment as part of the reorganization. The Company also changed how it measures business segment performance in 2020 as it no longer allocates acquisition and divestiture charges to its operating segments. Historical segment information has been retrospectively adjusted to reflect these changes. Electrical Americas and Electrical Global The Electrical Americas segment consists of electrical components, industrial components, power distribution and assemblies, residential products, single and three phase power quality, wiring devices, circuit protection, utility power distribution, power reliability equipment, and services that are primarily produced and sold in North and South America. The Electrical Global segment consists of electrical components, industrial components, power distribution and assemblies, single phase and three phase power quality, and services that are primarily produced and sold outside of North and South America; as well as hazardous duty electrical equipment, emergency lighting, fire detection, intrinsically safe explosion-proof instrumentation, and structural support systems that are produced and sold globally. The principal markets for these segments are industrial, institutional, governmental, utility, commercial, residential and information technology. These products are used wherever there is a demand for electrical power in commercial buildings, data centers, residences, apartment and office buildings, hospitals, factories, utilities, and industrial and energy facilities. The segments share certain common global customers, but a large majority of the customers are located regionally. Sales are made through distributors, resellers, and manufacturers' representatives, as well as directly to original equipment manufacturers, utilities, and certain other end users. Hydraulics The Hydraulics segment is a global leader in hydraulics components, systems and services for industrial and mobile equipment. Eaton offers a wide range of power products including pumps, motors and hydraulic power units; a broad range of controls and sensing products including valves, cylinders and electronic controls; a full range of fluid conveyance products including industrial and hydraulic hose, fittings, and assemblies, thermoplastic hose and tubing, couplings, connectors, and assembly equipment; and industrial drum and disc brakes. The principal markets for the Hydraulics segment include renewable energy, marine, agriculture, oil and gas, construction, mining, forestry, utility, material handling, truck and bus, machine tools, molding, primary metals, and power generation. Key manufacturing customers in these markets and other customers are located globally. Products are sold and serviced through a variety of channels.

The principal markets for the Vehicle segment are original equipment manufacturers and aftermarket customers of heavy-, medium-, and light-duty trucks, SUVs, CUVs, passenger cars and agricultural equipment. eMobility The eMobility segment designs, manufactures, markets, and supplies electrical and electronic components and systems that improve the power management and performance of both on-road and off-road vehicles. Products include high voltage inverters, converters, fuses, onboard chargers, circuit protection units, vehicle controls, power distribution, fuel tank isolation valves, and commercial vehicle hybrid systems. The principle markets for the eMobility segment are original equipment manufacturers and aftermarket customers of passenger cars, commercial vehicles, and construction, agriculture, and mining equipment. Other information The accounting policies of the business segments are generally the same as the policies described in Note 1 to the Consolidated Financial Statements contained in the 2019 Form 10-K, except that operating profit only reflects the service cost component and the cost of any special termination benefits related to pensions and other postretirement benefits. Intersegment sales and transfers are accounted for at the same prices as if the sales and transfers were made to third parties. These intersegment sales are eliminated in consolidation. Operating profit includes the operating profit from intersegment sales. For purposes of business segment performance measurement, the Company does not allocate items that are of a non-operating nature or are of a corporate or functional governance nature. Corporate expenses consist of all of the Company’s costs associated with acquisitions, divestitures, and gains and losses on the sale of certain businesses, and corporate office expenses including compensation, benefits, occupancy, depreciation, and other administrative costs. Identifiable assets of the business segments exclude goodwill, other intangible assets, and general corporate assets, which principally consist of certain cash, short-term investments, deferred income taxes, certain accounts receivable, certain property, plant and equipment, and certain other assets.

Basis of Accounting	The accompanying unaudited condensed consolidated financial statements of Eaton Corporation plc (Eaton or the Company) have been prepared in accordance with generally accepted accounting principles for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by United States generally accepted accounting principles (US GAAP) for complete financial statements. However, in the opinion of management, all adjustments (consisting of normal recurring accruals) have been made that are necessary for a fair presentation of the condensed consolidated financial statements for the interim periods. This Form 10-Q should be read in conjunction with the consolidated financial statements and related notes included in Eaton’s 2019 Form 10-K. The interim period results are not necessarily indicative of the results to be expected for the full year. Management has evaluated subsequent events through the date this Form 10-Q was filed with the Securities and Exchange Commission.
Adoption of New Accounting Standard	Adoption of New Accounting Standard Eaton adopted Accounting Standard Update 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, in the first quarter of 2020. This standard introduces new guidance for accounting for credit losses on receivables. The Company did not recognize a cumulative-effect adjustment to retained earnings as of January 1, 2020, as the adoption of this standard did not have a material impact to the Condensed Consolidated Financial Statements.
