Accounting Policies [Abstract]
Basis of Presentation and Responsibility for Interim Financial Statements	Basis of Presentation and Responsibility for Interim Financial Statements Business nVent Electric plc ("nVent," "we," "us," "our" or the "Company") is a leading global provider of electrical connection and protection solutions. The Company is comprised of three reporting segments: Enclosures, Electrical & Fastening Solutions and Thermal Management. The Company was incorporated in Ireland on May 30, 2017. Although our jurisdiction of organization is Ireland, we manage our affairs so that we are centrally managed and controlled in the United Kingdom (the "U.K.") and have tax residency in the U.K. Basis of presentation The accompanying unaudited condensed consolidated financial statements of nVent have been prepared following the requirements of the Securities and Exchange Commission ("SEC") for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by accounting principles generally accepted in the United States of America ("GAAP") can be condensed or omitted. We are responsible for the unaudited condensed consolidated financial statements included in this document. The financial statements include all normal recurring adjustments that are considered necessary for the fair presentation of our financial position and operating results. As these are condensed financial statements, one should also read our consolidated and combined financial statements and notes thereto, which are included in our Annual Report on Form 10-K Revenues, expenses, cash flows, assets and liabilities can and do vary during each quarter of the year. Additionally, in March 2020, the World Health Organization declared novel coronavirus 2019 (“COVID-19”) a pandemic. The effects of the COVID-19 pandemic have had and may continue to have an unfavorable impact on our business. The broader implication of COVID-19 on our results of operations and overall financial performance remains uncertain. We may experience reduced customer demand or constrained supply that could materially adversely impact our business, financial condition, results of operations and overall financial performance in future periods. Therefore, the results and trends in these interim financial statements may not be indicative of those for a full year.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Disaggregation of revenue We disaggregate our revenue from contracts with customers by geographic location and vertical for each of our segments, as we believe these best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. Geographic net sales information, based on geographic destination of the sale, was as follows: Three months ended September 30, 2021 In millions Enclosures Electrical & Fastening Solutions Thermal Management Total U.S. and Canada $ 216.6 $ 119.7 $ 75.9 $ 412.2 Developed Europe (1) 78.7 34.1 30.7 143.5 Developing (2) 35.2 10.6 28.3 74.1 Other Developed (3) 4.7 4.9 3.4 13.0 Total $ 335.2 $ 169.3 $ 138.3 $ 642.8 Nine months ended September 30, 2021 In millions Enclosures Electrical & Fastening Solutions Thermal Management Total U.S. and Canada $ 585.3 $ 341.0 $ 208.0 $ 1,134.3 Developed Europe (1) 230.4 99.9 89.6 419.9 Developing (2) 84.8 32.0 85.6 202.4 Other Developed (3) 12.1 13.5 10.8 36.4 Total $ 912.6 $ 486.4 $ 394.0 $ 1,793.0 Three months ended September 30, 2020 In millions Enclosures Electrical & Fastening Solutions Thermal Management Total U.S. and Canada $ 159.7 $ 109.2 $ 69.6 $ 338.5 Developed Europe (1) 60.4 26.3 32.0 118.7 Developing (2) 20.9 8.2 12.2 41.3 Other Developed (3) 3.7 4.0 3.1 10.8 Total $ 244.7 $ 147.7 $ 116.9 $ 509.3 Nine months ended September 30, 2020 In millions Enclosures Electrical & Fastening Solutions Thermal Management Total U.S. and Canada $ 474.6 $ 312.3 $ 191.4 $ 978.3 Developed Europe (1) 177.8 74.9 85.6 338.3 Developing (2) 59.9 23.2 45.5 128.6 Other Developed (3) 10.2 11.3 10.7 32.2 Total $ 722.5 $ 421.7 $ 333.2 $ 1,477.4 (1) Developed Europe includes Western Europe and Eastern Europe included in European Union.

Further, we determined that revenue in our chemical and petrochemical sub-verticals was better aligned with the industrial vertical, rather than the energy vertical, where it was previously reported. For comparability, we have reclassified revenue for the three and nine months ended September 30, 2020 to conform to the new presentation. This reclassification of revenue by vertical had no impact on our consolidated financial results. Contract balances Contract assets and liabilities consisted of the following: In millions September 30, 2021 December 31, 2020 $ Change % Change Contract assets $ 45.2 $ 45.6 $ (0.4) (0.9 %) Contract liabilities 18.4 11.3 7.1 62.8 % Net contract assets $ 26.8 $ 34.3 $ (7.5) (21.9 %) The $7.5 million decrease in net contract assets from December 31, 2020 to September 30, 2021 wa s primarily the result of timing of milestone payments. The majority of our contract liabilities at December 31, 2020 were recognized in revenue during the nine months ended September 30, 2021. There were no material impairment losses recognized on our contract assets for the three and nine months ended September 30, 2021 and 2020. Remaining performance obligations We have elected the practical expedient to disclose only the value of remaining performance obligations for contracts with an original expected length of one year or more. On September 30, 2021, we had $41.6 million of remaining performance obligations on contracts with an original expected duration of one year or more. We expect to recognize the majority of our remaining performance obligations on these contracts within the next 12 to 18 months.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Financial Instruments	Derivatives and Financial Instruments Derivative financial instruments We are exposed to market risk related to changes in foreign currency exchange rates. To manage the volatility related to this exposure, we periodically enter into a variety of derivative financial instruments. Our objective is to reduce, where it is deemed appropriate to do so, fluctuations in earnings and cash flows associated with changes in foreign currency exchange rates. The derivative contracts contain credit risk to the extent that our bank counterparties may be unable to meet the terms of the agreements. The amount of such credit risk is generally limited to the unrealized gains, if any, in such contracts. Such risk is minimized by limiting those counterparties to major financial institutions of high credit quality. Foreign currency contracts We conduct business in various locations throughout the world and are subject to market risk due to changes in the value of foreign currencies. We manage our economic and transaction exposure to certain market-based risks through the use of derivative instruments. These derivative instruments primarily consist of forward foreign currency contracts used to mitigate foreign currency exposure for certain foreign currency assets and liabilities. Our objective in holding these derivatives is to reduce the volatility in net earnings and cash flows associated with changes in foreign currency rates. The majority of our foreign currency contracts have an original maturity date of less than one year. These foreign currency contracts are not designated as hedging instruments; accordingly, changes in the fair value are recorded in current period earnings. At September 30, 2021 and December 31, 2020, we had outstanding foreign currency derivative contracts with gross notional U.S. dollar equivalent amounts of $154.4 million and $41.8 million, respectively. The impact of these contracts on the Condensed Consolidated Statements of Income (Loss) and Comprehensive Income (Loss) was not material for any period presented. Cross currency swaps At September 30, 2021 and December 31, 2020, we had outstanding cross currency swap agreements with a combined notional amount of $380.0 million and $329.0 million, respectively. The agreements are accounted for as either cash flow hedges, to hedge foreign currency fluctuations on certain intercompany debt, or as net investment hedges, to manage our exposure to fluctuations in the Euro-U.S. Dollar exchange rate. At September 30, 2021 and December 31, 2020, we had deferred foreign currency gains of $7.3 million and $6.9 million, respectively, in Accumulated other comprehensive loss associated with our cross currency swap activity. Interest rate swaps We are also exposed to interest rate risk fluctuations in connection with the planned issuance of long-term debt. To manage the volatility related to this exposure, we may use forward starting interest rate swaps to fix a portion of the interest cost associated with anticipated future financings. In 2020, we entered into a forward starting interest rate swap to hedge the variability of cash flows attributable to changes in the benchmark swap interest rate (London Inter-Bank Offer Rate) associated with the anticipated refinancing of the 2023 Notes (as defined below). The interest rate swap contract has a notional amount of $200.0 million. The interest rates swaps are accounted for as cash flow hedges since they hedge the risk of an increase in treasury rates for the forecasted interest payments of an anticipated fixed-rate debt issuance. At September 30, 2021 and December 31, 2020, we had deferred gains of $12.3 million and $2.1 million, respectively, in Accumulated other comprehensive loss associated with our interest rate swap activity. Fair value of financial instruments The following methods were used to estimate the fair values of each class of financial instruments: • short-term financial instruments (cash and cash equivalents, accounts and notes receivable, accounts and notes payable and variable-rate debt) — recorded amount approximates fair value because of the short maturity period; • long-term fixed-rate debt, including current maturities — fair value is based on market quotes available for issuance of debt with similar terms, which are inputs that are classified as Level 2 in the valuation hierarchy defined by the accounting guidance; • foreign currency contract and interest rate swap agreements — fair values are determined through the use of models that consider various assumptions, including time value, yield curves, as well as other relevant economic measures, which are inputs that are classified as Level 2 in the valuation hierarchy defined by the accounting guidance; and • deferred compensation plan assets (mutual funds, common/collective trusts and cash equivalents for payment of certain non-qualified benefits for retired, terminated and active employees) — fair value of mutual funds and cash equivalents are based on quoted market prices in active markets that are classified as Level 1 in the valuation hierarchy defined by the accounting guidance; fair value of common/collective trusts are valued at net asset value ("NAV"), which is based on the fair value of underlying securities owned by the fund divided by the number of shares outstanding. The recorded amounts and estimated fair values of total debt, excluding unamortized issuance costs and discounts, were as follows: September 30, December 31, In millions Recorded Fair Recorded Fair Variable rate debt $ 179.9 $ 179.9 $ 152.1 $ 152.1 Fixed rate debt 800.0 897.3 800.0 915.2 Total debt $ 979.9 $ 1,077.2 $ 952.1 $ 1,067.3 Financial assets and liabilities measured at fair value on a recurring basis were as follows: September 30, 2021 In millions Level 1 Level 2 Level 3 NAV Total Foreign currency contract liabilities $ — $ (6.8) $ — $ — $ (6.8) Foreign currency contract assets — 3.8 — — 3.8 Interest rate swap assets — 12.3 — — 12.3 Deferred compensation plan assets 15.6 — — 4.8 20.4 Total recurring fair value measurements $ 15.6 $ 9.3 $ — $ 4.8 $ 29.7 December 31, 2020 In millions Level 1 Level 2 Level 3 NAV Total Foreign currency contract liabilities $ — $ (14.3) $ — $ — $ (14.3) Foreign currency contract assets — 0.9 — — 0.9 Interest rate swap assets — 2.1 — — 2.1 Deferred compensation plan assets 15.6 — — 4.4 20.0 Total recurring fair value measurements $ 15.6 $ (11.3) $ — $ 4.4 $ 8.7

(“nVent Finance” or "Subsidiary Issuer"), a 100-percent owned subsidiary of nVent, issued $300.0 million aggregate principal amount of 3.950% senior notes due 2023 (the "2023 Notes") and $500.0 million aggregate principal amount of 4.550% senior notes due 2028 (the "2028 Notes" and, collectively with the 2023 Notes, the "Notes"). Interest on the Notes is payable semi-annually in arrears on April 15 and October 15 of each year. The Notes are fully and unconditionally guaranteed as to payment by nVent (the "Parent Company Guarantor"). There are no subsidiaries that guarantee the Notes. The Parent Company Guarantor is a holding company that has no independent assets or operations unrelated to its investments in consolidated subsidiaries. The Subsidiary Issuer is a holding company that has no independent assets or operations unrelated to its investments in consolidated subsidiaries and the issuance of the Notes and other external debt. The Parent Company Guarantor’s principal source of cash flow, including cash flow to make payments on the Notes pursuant to the guarantees, is dividends from its subsidiaries. The Subsidiary Issuer’s principal source of cash flow is interest income from its subsidiaries. None of the subsidiaries of the Parent Company Guarantor or the Subsidiary Issuer is under any direct obligation to pay or otherwise fund amounts due on the Notes or the guarantees, whether in the form of dividends, distributions, loans or other payments. In addition, there may be statutory and regulatory limitations on the payment of dividends from certain subsidiaries of the Parent Company Guarantor or the Subsidiary Issuer. If such subsidiaries are unable to transfer funds to the Parent Company Guarantor or the Subsidiary Issuer and sufficient cash or liquidity is not otherwise available, the Parent Company Guarantor or the Subsidiary Issuer may not be able to make principal and interest payments on their outstanding debt, including the Notes or the guarantees. The Notes constitute general unsecured senior obligations of the Subsidiary Issuer and rank equally in right of payment with all existing and future unsubordinated and unsecured indebtedness and liabilities of the Subsidiary Issuer. The guarantees of the Notes by the Parent Company Guarantor constitute general unsecured obligations of the Parent Company Guarantor and rank equally in right of payment with all existing and future unsubordinated and unsecured indebtedness and liabilities of the Subsidiary Issuer. Subject to certain qualifications and exceptions, the indenture pursuant to which the Notes were issued contains covenants that, among other things, restrict nVent’s, nVent Finance’s and certain subsidiaries’ ability to merge or consolidate with another person, create liens or engage in sale and lease-back transactions. There are no significant restrictions on the ability of nVent to obtain funds from its subsidiaries by dividend or loan. None of the assets of nVent or its subsidiaries represents restricted net assets pursuant to the guidelines established by the SEC. Senior credit facilities In March 2018, the Company and its subsidiaries nVent Finance and Hoffman Schroff Holdings, Inc. entered into a credit agreement with a syndicate of banks providing for a five-year $200.0 million senior unsecured term loan facility and a five-year $600.0 million senior unsecured revolving credit facility. In September 2021, the Company and its subsidiaries nVent Finance and Hoffman Schroff Holdings, Inc. entered into an amended and restated credit agreement (the "Credit Agreement") with a syndicate of banks providing for a five-year $300.0 million senior unsecured term loan facility (the "Term Loan Facility") and a five-year $600.0 million senior unsecured revolving credit facility (the "Revolving Credit Facility") and, together with the Term Loan Facility, the "Senior Credit Facilities". Borrowings under the Term Loan Facility are permitted on a delayed draw basis during the first year of the five-year term of the Term Loan Facility, and borrowings under the Revolving Credit Facility are permitted from time to time during the full five-year term of the Revolving Credit Facility. The Credit Agreement amends and restates in its entirety the March 2018 credit agreement. We have the option to request to increase the Revolving Credit Facility in an aggregate amount of up to $300.0 million, subject to customary conditions, including the commitment of the participating lenders. Borrowings under the Senior Credit Facilities bear interest at a rate equal to an adjusted base rate, London Interbank Offered Rate (“LIBOR”), Euro Interbank Offer Rate (“EURIBOR”) or Sterling Overnight Index Average (“SONIA”), plus, in each case, an applicable margin. The applicable margin will be based on, at nVent Finance’s election, the Company's leverage level or public credit rating. As of September 30, 2021, the borrowing capacity under the Term Loan Facility on a delayed draw basis was $200.0 million, and the borrowing capacity under the Revolving Credit Facility was $520.1 million. Our debt agreements contain certain financial covenants, the most restrictive of which are in the Senior Credit Facilities, including that we may not permit (i) the ratio of our consolidated debt (net of our consolidated unrestricted cash in excess of $5.0 million but not to exceed $250.0 million) to our consolidated net income (excluding, among other things, non-cash gains and losses) before interest, taxes, depreciation, amortization and non-cash share-based compensation expense ("EBITDA") on the last day of any period of four consecutive fiscal quarters to exceed 3.75 to 1.00 and (ii) the ratio of our EBITDA to our consolidated interest expense for the same period to be less than 3.00 to 1.00. In addition, subject to certain qualifications and exceptions, the Senior Credit Facilities also contain covenants that, among other things, restrict our ability to create liens, merge or consolidate with another person, make acquisitions and incur subsidiary debt. As of September 30, 2021, we were in compliance with all financial covenants in our debt agreements, and there is no material uncertainty about our ongoing ability to meet those covenants. Debt outstanding, excluding unamortized issuance costs and discounts, at September 30, 2021 matures on a calendar year basis as follows: Q4 In millions 2021 2022 2023 2024 2025 2026 Thereafter Total Contractual debt obligation maturities $ 1.3 $ 5.0 $ 305.0 $ 5.6 $ 7.5 $ 155.5 $ 500.0 $ 979.9

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Warranties and guarantees In connection with the disposition of our businesses or product lines, we may agree to indemnify purchasers for various potential liabilities relating to the sold business, such as pre-closing tax, product liability, warranty, environmental, or other obligations. The subject matter, amounts and duration of any such indemnification obligations vary for each type of liability indemnified and may vary widely from transaction to transaction. Generally, the maximum obligation under such indemnifications is not explicitly stated and as a result, the overall amount of these obligations cannot be reasonably estimated. Historically, we have not made significant payments for these indemnifications. We believe that if we were to incur a loss in any of these matters, the loss would not have a material effect on our financial position, results of operations or cash flows. We recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. We provide service and warranty policies on our products. Liability under service and warranty policies is based upon a review of historical warranty and service claim experience. Adjustments are made to accruals as claim data and historical experience warrant. Our liability for service and product warranties as of September 30, 2021 and December 31, 2020 was not material. Stand-by letters of credit, bank guarantees and bonds In the ordinary course of business, we are required to commit to bonds, letters of credit and bank guarantees that require payments to our customers for any non-performance. The outstanding face value of these instruments fluctuates with the value of our projects in process and in our backlog. In addition, we issue financial stand-by letters of credit primarily to secure our performance to third parties under self-insurance programs. As of September 30, 2021 and December 31, 2020, the outstanding value of bonds, letters of credit and bank guarantees totaled $37.0 million and $43.8 million, respectively.
