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. Therefore, the results and trends in these interim financial statements may not be indicative of those for a full year. We may experience changes in customer demand or constrained supply that could materially adversely impact our business, financial condition, results of operations and overall financial performance in future periods.

Revenue	Revenue Disaggregation of revenue We disaggregate our revenue 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.

For comparability, we have reclassified revenue for the three and nine months ended September 30, 2022 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, 2023 December 31, 2022 $ Change % Change Contract assets $ 44.2 $ 45.6 $ (1.4) (3.1 %) Contract liabilities 18.7 22.7 (4.0) (17.6 %) Net contract assets $ 25.5 $ 22.9 $ 2.6 11.4 % The $2.6 million increase in net contract assets from December 31, 2022 to September 30, 2023 wa s primarily the result of the timing of milestone payments. The majority of our contract liabilities at December 31, 2022 were recognized in revenue during the nine months ended September 30, 2023. There were no material impairment losses recognized on our contract assets for the three and nine months ended September 30, 2023 and 2022. 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, 2023, we had $18.0 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.

Acquisitions	Sep. 30, 2023
Business Combination and Asset Acquisition [Abstract]
Acquisitions	Acquisitions On May 18, 2023, as part of our Electrical & Fastening Solutions reporting segment, we completed the acquisition of ECM Investors, LLC, the parent of ECM Industries, LLC ("ECM Industries"), for approximately $1.1 billion in cash, subject to customary adjustments. ECM Industries is a leading provider of high-value electrical connectors, tools and test instruments and cable management. The purchase price was funded primarily through borrowings under the 2033 Notes and 2023 Term Loan Facility (as described in Note 9 below). The purchase price has been preliminarily allocated based on the estimated fair value of assets acquired and liabilities assumed at the date of the ECM Industries acquisition. The preliminary purchase price allocation is subject to further refinement and may require significant adjustments to arrive at the final purchase price allocation. These changes will primarily relate to the impacts associated with income taxes and other accruals. There can be no assurance that such finalization will not result in material changes from the preliminary purchase price allocation. The following table summarizes our preliminary estimates of the fair values of the assets acquired and liabilities assumed in the ECM Industries acquisition as previously reported and revised as of September 30, 2023: In millions As Originally Reported As Revised Cash $ 45.7 $ 45.7 Accounts receivable 78.1 78.1 Inventories 107.8 104.0 Other current assets 4.9 4.9 Property, plant and equipment 81.1 75.9 Identifiable intangible assets 519.8 524.0 Goodwill 361.5 371.7 Other assets 16.6 16.7 Current liabilities (51.5) (51.4) Other liabilities (26.5) (35.9) Purchase price $ 1,137.5 $ 1,133.7 The excess purchase price over tangible net assets and identified intangible assets acquired has been allocated to goodwill in the amount of $371.7 million, substantially all of which is expected to be deductible for income tax purposes. Identifiable intangible assets acquired included $113.7 million of trade name intangible assets, a majority of which are indefinite-lived, $381.7 million of definite-lived customer relationships with an estimated useful life of 20 years, and $22.0 million of definite-lived proprietary technology intangible assets with an estimated useful life of 7 years. The fair values of trade names and proprietary technology acquired in the acquisition were determined using a relief-from-royalty method, and customer relationships acquired were determined using a multi-period excess earnings method. These methods utilize unobservable inputs that are significant to these fair value measurements and thus classified as Level 3 of the fair value hierarchy. ECM Industries net sales and operating income for the three months ended September 30, 2023 were $98.4 million and $10.5 million, respectively. ECM Industries net sales and operating income for the period from the acquisition date to September 30, 2023 were $148.1 million and $14.3 million, respectively. ECM Industries operating income for the three and nine months ended September 30, 2023 inclu des $7.6 million and $11.2 million of identifiable intangible asset amortization expense, respectively, and $11.8 million and $17.7 million of expense related to the fair market value inventory step-up, respectively. The following table presents unaudited pro forma financial information as if the ECM Industries acquisition had occurred on January 1, 2022: Three months ended Nine months ended In millions, except per-share date September 30, September 30, September 30, September 30, Pro forma net sales $ 858.8 $ 847.9 $ 2,558.8 $ 2,477.9 Pro forma net income 115.9 92.8 341.4 206.1 Pro forma earnings per ordinary share Basic $ 0.70 $ 0.56 $ 2.06 $ 1.24 Diluted 0.69 0.55 2.03 1.23 The unaudited pro forma results include adjustments for the amortization of acquired intangible assets, depreciation for the fair value adjustment to acquisition-date fixed assets and interest expense on debt issued to finance the acquisition, as well as the related income tax impact. The unaudited pro forma results for the three and nine months ended September 30, 2023 exclude the impact of $13.8 million and $30.8 million, respectively, of transaction-related charges, acquisition-related bridge financing costs and non-recurring expense related to the fair value inventory step-up. The three and nine months ended September 30, 2022 were adjusted to include zero and $31.1 million, respectively, of transaction-related charges, acquisition-related bridge financing costs and non-recurring expense related to the fair market value inventory step-up. The pro forma condensed consolidated financial information has been prepared for comparative purposes only and includes certain adjustments, as noted above. The adjustments are estimates based on currently available information and actual amounts may differ materially from these estimates. They do not reflect the effect of costs or synergies that would have been expected to result from the integration of the ECM Industries acquisition. The pro forma information does not purport to be indicative of the results of operations that actually would have resulted had the ECM Industries acquisition occurred on January 1, 2022. On July 10, 2023, we acquired TEXA Industries for approximately $34.8 million in cash, subject to customary purchase price adjustments. TEXA Industries is an Italian manufacturer of industrial cooling applications that we will market as part of the nVent HOFFMAN product line within our Enclosures segment. We acquired $5.2 million of debt with the TEXA Industries acquisition, which we repaid in full in the third quarter of 2023. The excess purchase price over tangible net assets and identified intangible assets acquired has been preliminarily allocated to goodwill in the amount of $11.5 million, none of which is expected to be deductible for income tax purposes. Identifiable intangible assets acquired included $12.4 million of definite-lived customer relationships with an estimated useful life of 13 years. The preliminary purchase price allocation is subject to further refinement and may require significant adjustments to arrive at the final purchase price allocation. The pro forma impact of the TEXA Industries acquisition is not material.

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, 2023 and December 31, 2022, we had outstanding foreign currency derivative contracts with gross notional U.S. dollar equivalent amounts of $153.8 million and $145.7 million, respectively. The impact of these contracts on the Condensed Consolidated Statements of Income and Comprehensive Income was not material for any period presented. Cross currency swaps At September 30, 2023 and December 31, 2022, we had outstanding cross currency swap agreements with a combined notional amount of $249.9 million and $345.1 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. In 2023, a cash flow hedge instrument and a net investment hedge instrument each reached maturity, resulting in settlement amounts reflected as a component of financing and investing cash inflows in the amount of $4.5 million and $3.1 million, respectively. Upon maturity of the previous agreement, we entered into a new net investment hedge of certain Euro-denominated subsidiaries to manage exposure to fluctuations in the Euro-U.S. dollar exchange rate with a gross notional U.S. dollar equivalent amount of $66.1 million. In the third quarter of 2022, as a result of an early settlement of a cash flow hedge instrument, $10.0 million of cash flows has been reflected as a component of financing cash flows and $0.3 million of expense was recorded to Selling, general and administrative expense from Accumulated other comprehensive loss . We entered a cross currency swap with a gross notional U.S. dollar equivalent amount of $121.0 million to replace the terminated agreement, which we designated as a fair value hedge to offset foreign currency risk associated with intercompany debt. At September 30, 2023 and December 31, 2022, we had deferred foreign currency gains of $5.1 million and $18.9 million, respectively, in Accumulated other comprehensive loss associated with our cross currency swap activity. Fair value of financial instruments The following methods were used to estimate the fair values of each class of financial instrument: • 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; • cross currency swap and foreign currency contract 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 $ 573.8 $ 573.8 $ 288.8 $ 288.8 Fixed rate debt 1,300.0 1,182.2 800.0 717.7 Total debt $ 1,873.8 $ 1,756.0 $ 1,088.8 $ 1,006.5 Financial assets and liabilities measured at fair value on a recurring basis were as follows: Recurring fair value measurements September 30, 2023 In millions Level 1 Level 2 Level 3 NAV Total Cross currency swap liabilities $ — $ (6.0) $ — $ — $ (6.0) Cross currency swap assets — 9.2 — — 9.2 Foreign currency contract liabilities — (1.2) — — (1.2) Foreign currency contract assets — 1.1 — — 1.1 Deferred compensation plan assets 11.9 — — 5.5 17.4 Total recurring fair value measurements $ 11.9 $ 3.1 $ — $ 5.5 $ 20.5 Recurring fair value measurements December 31, 2022 In millions Level 1 Level 2 Level 3 NAV Total Cross currency swap liabilities $ — $ (4.8) $ — $ — $ (4.8) Cross currency swap assets — 22.4 — — 22.4 Foreign currency contract liabilities — (1.5) — — (1.5) Foreign currency contract assets — 0.5 — — 0.5 Deferred compensation plan assets 11.8 — — 4.9 16.7 Total recurring fair value measurements $ 11.8 $ 16.6 $ — $ 4.9 $ 33.3

(“nVent Finance” or "Subsidiary Issuer"), a 100-percent owned subsidiary of nVent, issued $500.0 million aggregate principal amount of 4.550% senior notes due 2028 (the "2028 Notes"). In November 2021, nVent Finance issued $300.0 million aggregate principal amount of 2.750% senior notes due 2031 (the "2031 Notes"). In May 2023, to finance the acquisition of ECM Industries, nVent Finance issued $500.0 million aggregate principal amount of 5.650% Senior Notes due 2033 (the "2033 Notes" and, collectively with the 2028 Notes and the 2031 Notes, the "Notes"). Interest on the 2028 Notes is payable semi-annually in arrears on April 15 and October 15 of each year, and interest on the 2031 Notes and 2033 Notes is payable semi-annually in arrears on May 15 and November 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 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 "2021 Term Loan Facility") and a five-year $600.0 million senior unsecured revolving credit facility (the "Revolving Credit Facility" and, together with the 2021 Term Loan Facility, the "Senior Credit Facilities"). Borrowings under the 2021 Term Loan Facility were permitted on a delayed draw basis during the first year of the five-year term of the 2021 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. In September 2022, nVent exercised the delayed draw provision of the 2021 Term Loan Facility, increasing the total borrowings under the 2021 Term Loan Facility by $200.0 million to $300.0 million. nVent Finance has 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. As of September 30, 2023, the borrowing capacity under the Revolving Credit Facility was $600.0 million. Borrowings under the Senior Credit Facilities bear interest at a rate equal to an adjusted base rate, the Secured Overnight Financing Rate ("SOFR"), 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. In April 2023, nVent and nVent Finance entered into a loan agreement providing for another unsecured term loan facility of $300.0 million for five years (the "2023 Term Loan Facility"), which was used to fund the acquisition of ECM Industries. The 2023 Term Loan Facility bears interest at a rate equal to an adjusted base rate or adjusted term SOFR plus an applicable margin. The applicable margin will be based on, at nVent Finance’s election, the Company's leverage level or public credit rating. Our debt agreements contain certain financial covenants, the most restrictive of which are in the Senior Credit Facilities and the 2023 Term Loan Facility, 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 (each a "testing period") to exceed 3.75 to 1.00 (or, at nVent Finance's election and subject to certain conditions, 4.25 to 1.00 for four testing periods in connection with certain material acquisitions, which we elected in connection with the acquisition of ECM Industries in May 2023 for each of the next four fiscal quarters beginning in the second quarter of 2023) 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 and the 2023 Term Loan Facility 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, 2023, we were in compliance with all financial covenants in our debt agreements. Debt outstanding at September 30, 2023, excluding unamortized issuance costs and discounts, matures on a calendar year basis as follows: Q4 In millions 2023 2024 2025 2026 2027 2028 Thereafter Total Contractual debt obligation maturities $ 7.5 $ 31.9 $ 37.5 $ 253.1 $ 22.5 $ 721.3 $ 800.0 $ 1,873.8

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, 2023 and December 31, 2022 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, 2023 and December 31, 2022, the outstanding value of bonds, letters of credit and bank guarantees totaled $39.5 million and $38.0 million, respectively.

Share-Based Payment Arrangement [Abstract]
Share-Based Compensation	Share-Based Compensation Total share-based compensation expense for the three and nine months ended September 30, 2023 and 2022, was as follows: Three months ended Nine months ended In millions September 30, September 30, September 30, September 30, Restricted stock units $ 3.0 $ 2.5 $ 8.4 $ 7.4 Performance share units 1.9 2.3 5.7 7.3 Stock options 1.2 1.1 3.4 3.1 Total $ 6.1 $ 5.9 $ 17.5 $ 17.8 In the first quarter of 2023, we issued our annual share-based compensation grants under the 2018 Omnibus Incentive Plan to eligible employees. The total number of awards issued was approximately 0.6 million, of which 0.2 million were restricted stock units ("RSUs"), 0.1 million were performance share units ("PSUs") and 0.3 million were stock options. The weighted-average grant date fair value of the RSUs, PSUs and stock options issued was $46.15, $68.72 and $16.56, respectively. We estimated the fair value of each stock option award issued in the annual share-based compensation grant using a Black-Scholes option pricing model, modified for dividends, and using the following assumptions: 2023 Annual Grant Risk-free interest rate 3.77 % Expected dividend yield 1.73 % Expected share price volatility 36.6 % Expected term (years) 6.5 These estimates require us to make assumptions based on historical results, observance of trends in our share price, changes in option exercise behaviors, future expectations and other relevant factors. If other assumptions had been used, share-based compensation expense, as calculated and recorded under the accounting guidance, could have been affected. We based the expected life assumption on historical experience as well as the terms and vesting periods of the options granted. For purposes of determining expected volatility, we considered historical volatilities of peer companies over a period approximately equal to the expected option term. The risk-free rate for periods that coincide with the expected life of the options is based on the U.S. Treasury Department yield curve in effect at the time of grant.
