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 2021 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. Certain prior year amounts have been reclassified to conform to the current year presentation.

Business Combination and Asset Acquisition [Abstract]
ACQUISITIONS AND DIVESTITURES OF BUSINESSES	ACQUISITIONS AND DIVESTITURE OF BUSINESSES Acquisition of Tripp Lite On March 17, 2021, Eaton acquired Tripp Lite for $1.65 billion, net of cash received. Tripp Lite is a leading supplier of power quality products and connectivity solutions including single-phase uninterruptible power supply systems, rack power distribution units, surge protectors, and enclosures for data centers, industrial, medical, and communications markets in the Americas. Tripp Lite is reported within the Electrical Americas business segment. The acquisition of Tripp Lite 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. During the measurement period which ended in March 2022, opening balance sheet adjustments were made to finalize Eaton's fair value estimates based on the final valuations received, which are summarized in the table below. The measurement period adjustments did not have a material impact to the Consolidated Statements of Income. (In millions) Preliminary Allocation Measurement Period Adjustments Final Short-term investments $ 5 $ — $ 5 Accounts receivable 94 (1) 93 Inventory 184 (5) 179 Prepaid expenses and other current assets 6 (1) 5 Property, plant and equipment 6 (5) 1 Other intangible assets 630 (26) 604 Other assets — 2 2 Accounts payable (13) — (13) Other current liabilities (32) (2) (34) Other noncurrent liabilities (157) (10) (167) Total identifiable net assets 723 (48) 675 Goodwill 928 48 976 Total consideration, net of cash received $ 1,651 $ — $ 1,651 Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the anticipated synergies of acquiring Tripp Lite. Goodwill recognized as a result of the acquisition is not deductible for tax purposes. The estimated fair values of the customer relationships, trademarks and technology intangible assets of $539 million, $33 million and $32 million, respectively, were determined using either the relief-from-royalty model or the multi-period excess earnings model, which are discounted cash flow models that rely on the Company's estimates. These estimates require judgment of future revenue growth rates, future margins, 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. The estimated useful lives for customer relationships, trademarks and technology intangible assets were 20 years, 15 years, and 5 years, respectively. See Note 6 for additional information about goodwill. Eaton's 2021 Condensed Consolidated Financial Statements include Tripp Lite’s results of operations, including sales of $26 million, from the date of acquisition through March 31, 2021. Acquisition of Mission Systems On June 1, 2021, Eaton acquired Mission Systems for $2.80 billion, net of cash received. Mission Systems is a leading manufacturer of air-to-air refueling systems, environmental systems, and actuation primarily for defense markets. Mission Systems is reported within the Aerospace business segment. The acquisition of Mission Systems 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. There has not been a material change from the estimated fair values of the assets acquired and liabilities assumed presented in Note 2 to the Consolidated Financial Statements in the 2021 Form 10-K. Draft third-party valuations for Other intangible assets and Property, plant and equipment have been received. These preliminary estimates will be finalized in the second quarter of 2022 when our review of the third-party valuations are completed, further information becomes available and additional analyses are performed, and these differences could have a material impact on Eaton's preliminary purchase price allocation. Sale of Hydraulics business On August 2, 2021, Eaton completed the sale of the Hydraulics business to Danfoss A/S. As a result of the sale, the Company received $3.1 billion, net of cash sold, and recognized a pre-tax gain of $617 million in 2021. According to the terms of the sales agreement, the Company finalized negotiations of post-closing adjustments with Danfoss A/S during the first quarter of 2022. As a result of these negotiations, the Company recognized an additional pre-tax gain of $24 million. The business had sales of $1.3 billion in 2021 through the date of the sale. Acquisition of Royal Power Solutions On January 5, 2022, Eaton acquired Royal Power Solutions for $612 million, net of cash received. Royal Power Solutions is a U.S. based manufacturer of high-precision electrical connectivity components used in electric vehicle, energy management, industrial and mobility markets. Royal Power Solutions is reported within the eMobility business segment. The acquisition of Royal Power Solutions 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. 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. (In millions) January 5, 2022 Accounts receivable $ 36 Inventory 43 Prepaid expenses and other current assets 1 Property, plant and equipment 25 Other intangible assets 306 Other assets 21 Accounts payable (24) Other current liabilities (10) Other noncurrent liabilities (70) Total identifiable net assets 328 Goodwill 284 Total consideration, net of cash received $ 612 Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the anticipated synergies of acquiring Royal Power Solutions. Goodwill recognized as a result of the acquisition is not deductible for tax purposes. Other intangible assets of $306 million 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 2022 Condensed Consolidated Financial Statements include Royal Power Solutions' results of operations, including segment operating profit of $5 million on sales of $38 million, from the date of acquisition through March 31, 2022.

REVENUE RECOGNITION

REVENUE RECOGNITION	3 Months Ended

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. Control is transferred when the customer has the ability to direct the use of and obtain benefits from the goods or services. Sales are measured at the amount of consideration the Company expects to be paid in exchange for these products or services. The following table provides disaggregated sales by lines of businesses, geographic destination, market channel or end market, as applicable, for the Company's operating segments: Three months ended (In millions) 2022 2021 Electrical Americas Products $ 603 $ 520 Systems 1,288 1,102 Total $ 1,891 $ 1,622 Electrical Global Products $ 876 $ 713 Systems 561 540 Total $ 1,437 $ 1,253 Hydraulics United States $ — $ 222 Rest of World — 339 Total $ — $ 561 Aerospace Original Equipment Manufacturers $ 293 $ 208 Aftermarket 221 146 Industrial and Other 204 165 Total $ 718 $ 519 Vehicle Commercial $ 402 $ 342 Passenger and Light Duty 269 312 Total $ 671 $ 654 eMobility $ 126 $ 83 Total net sales $ 4,843 $ 4,692 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 receivable from customers were $3,216 million and $2,896 million at March 31, 2022 and December 31, 2021, 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 $194 million and $187 million at March 31, 2022 and December 31, 2021, respectively, and are recorded in Prepaid expenses and other current assets. The increase in unbilled receivables reflects higher revenue recognized from increased business activity in 2022. Changes in the deferred revenue liabilities are as follows: (In millions) Deferred Revenue Balance at January 1, 2022 $ 422 Customer deposits and billings 342 Revenue recognized in the period (334) Translation (2) Balance at March 31, 2022 $ 428 (In millions) Deferred Revenue Balance at January 1, 2021 $ 257 Customer deposits and billings 276 Revenue recognized in the period (262) Translation and other (3) Balance at March 31, 2021 $ 268 Deferred revenue liabilities of $401 million and $395 million as of March 31, 2022 and December 31, 2021, respectively, were included in Other current liabilities with the remaining balance presented in Other noncurrent liabilities.

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, their financial liquidity position. 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-off 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 $42 million at March 31, 2022 and December 31, 2021. The change in the allowance for credit losses includes expense and net write-offs, none of which are significant.

The freeze was effective January 1, 2021 for non-union U.S. employees whose retirement benefit was determined under a cash balance formula and is effective January 1, 2026 for non-union U.S. employees whose retirement benefit is determined under a final average pay formula. During the first quarter of 2022, the Company recognized settlement losses from lump-sum distributions of $14 million, and remeasured certain pension plans as a result of lump-sum distributions exceeding or expected to exceed the sum of service and interest costs for the year. These remeasurements resulted in increases of $32 million in pension assets, decreases of $15 million in pension liabilities, and decreases of $47 million in other comprehensive loss. The components of retirement benefits expense (income) other than service costs are included in Other income - net.

LEGAL CONTINGENCIES	LEGAL CONTINGENCIESEaton is subject to a broad range of claims, administrative and legal proceedings such as lawsuits that relate to contractual allegations and indemnity claims, tax audits, patent infringement, personal injuries, antitrust matters, and employment-related matters. Eaton is also subject to asbestos claims from historic products which may have contained asbestos. Insurance may cover some of the costs associated with these claims and proceedings. Although it is not possible to predict with certainty the outcome or cost of these matters, the Company believes they will not have a material adverse effect on the Condensed Consolidated Financial Statements.

INCOME TAXES

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The effective income tax rate for the first quarter of 2022 was expense of 13.9% compared to expense of 14.7% for the first quarter of 2021. The decrease in the effective tax rate in the first quarter of 2022 was primarily due to the excess tax benefits recognized for employee share-based payments in the first quarter of 2022. Brazil Tax Years 2005-2012 The Company has two Brazilian tax cases primarily relating to the amortization of certain goodwill generated from the acquisition of third-party businesses and corporate reorganizations. One case involves tax years 2005-2008 (Case 1), and the other involves tax years 2009-2012 (Case 2). Case 2 is proceeding on a more accelerated timeline than Case 1. For Case 2, the Company received a tax assessment in 2014 that included interest and penalties. In November 2019, the Company received an unfavorable result at the final tax administrative appeals level, resulting in an alleged tax deficiency of $29 million plus $107 million of interest and penalties (translated at the March 31, 2022 exchange rate). The Company is challenging this assessment in the judicial system and, on April 18, 2022, received an unfavorable decision at the first judicial level. On April 27, 2022, the Company filed a motion for clarification relating to that decision, which is currently pending with the court. The Company intends to continue its challenge of this assessment in the judicial system, including appealing the April 18, 2022 decision, if necessary. As previously disclosed for Case 1, the Company received a separate tax assessment alleging a tax deficiency of $35 million plus $115 million of interest and penalties (translated at the March 31, 2022 exchange rate), which the Company is challenging in the judicial system. This case is still pending resolution at the first judicial level. Both cases are expected to take several years to resolve through the Brazilian judicial system and require provision of certain assets as security for the alleged deficiencies. As of March 31, 2022, the Company pledged Brazilian real estate assets with net book value of $22 million and provided additional security in the form of bank secured bonds totaling $113 million and a cash deposit of $20 million (translated at the March 31, 2022 exchange rate). The Company believes that the final resolution of both of the assessments will not have a material impact on its condensed consolidated financial statements. The ultimate outcome of these matters cannot be predicted with certainty given the complex nature of tax controversies. Should the ultimate outcome of these matters deviate from our reasonable expectations, they may have a material adverse impact on the Company’s condensed consolidated financial statements. However, Eaton believes that its interpretations of tax laws and application of tax laws to its facts are correct.

Stockholders' Equity Note [Abstract]
EQUITY	EQUITY On February 27, 2019, the Board of Directors adopted a share repurchase program for share repurchases up to $5.0 billion of ordinary shares (2019 Program). On February 23, 2022, the Board renewed the 2019 Program by providing authority for up to $5.0 billion in repurchases to be made during the three-year period commencing on that date (2022 Program). Under the 2022 Program, the ordinary shares are expected to be repurchased over time, depending on market conditions, the market price of ordinary shares, capital levels, and other considerations.

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 and contingent consideration recognized at fair value, and the fair value measurements used, is as follows: (In millions) Total Level 1 Level 2 Level 3 March 31, 2022 Cash $ 237 $ 237 $ — $ — Short-term investments 268 268 — — Net derivative contracts 44 — 44 — Contingent consideration from acquisition of Green Motion (57) — — (57) December 31, 2021 Cash $ 297 $ 297 $ — $ — Short-term investments 271 271 — — Net derivative contracts 41 — 41 — Contingent consideration from acquisition of Green Motion (57) — — (57) 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. On March 22, 2021, Eaton acquired Green Motion SA, a leading designer and manufacturer of electric vehicle charging hardware and related software based in Switzerland. Green Motion SA was acquired for $106 million, including $49 million of cash paid at closing and $57 million of estimated fair value of contingent future consideration based on 2023 and 2024 revenue performance. The fair value of contingent consideration liabilities is estimated by discounting contingent payments expected to be made, and may increase or decrease based on changes in revenue estimates and discount rates, with a maximum possible undiscounted value of $109 million. Other Fair Value Measurements Long-term debt and the current portion of long-term debt had a carrying value of $8,491 million and fair value of $8,709 million at March 31, 2022 compared to $8,566 million and $9,232 million, respectively, at December 31, 2021. The fair value of Eaton's debt instruments were estimated using prevailing market interest rates on debt with similar creditworthiness, terms and maturities and is considered a Level 2 fair value measurement.

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 non-derivative net investment hedging instruments had a carrying value on an after-tax basis of $2,819 million at March 31, 2022 and $2,880 million at December 31, 2021.

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. The cash flows resulting from the settlement of these derivatives have been classified in investing activities in the Condensed Consolidated Statement of Cash Flows. As of March 31, 2022, the volume of outstanding commodity contracts that were entered into to hedge forecasted transactions: Commodity March 31, 2022 Term Copper 10 Millions of pounds 1 to 12 months Gold 1,418 Troy ounces 1 to 12 months Silver 560,367 Troy ounces 1 to 12 months The following amounts were recorded on the Consolidated Balance Sheets related to fixed-to-floating interest rate swaps: (In millions) Carrying amount of the hedged 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, 2022 December 31, 2021 March 31, 2022 December 31, 2021 Long-term debt $ (2,413) $ (2,413) $ (70) $ (84) (a) At March 31, 2022 and December 31, 2021, these amounts include the cumulative liability amount of fair value hedging adjustments remaining for which the hedge accounting has been discontinued of $70 million and $33 million, respectively.
