It provides both AFCI (Arc Fault Circuit Interrupter) and GFCI (Ground Fault Circuit Interrupter) protection in a single plug-in unit, meeting NEC code requirements for combination-type protection in residential and light commercial applications. The breaker carries a 10 kA interrupt rating and is designed for use in THQL-compatible load centers. Licensed electricians install this device as a direct code-compliant upgrade or replacement in branch circuit panelboards.\u003c\/p\u003e\n\u003cp\u003eThis breaker is suited for residential branch circuits requiring dual-function protection, including bedroom circuits, kitchen circuits, and other locations where both arc fault and ground fault protection are mandated by the National Electrical Code. Its plug-in connection type allows straightforward installation in compatible load centers without requiring adapter hardware. The 14 to 8 AWG wire size range accommodates standard residential branch circuit conductors.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual AFCI and GFCI protection in a single 1-pole breaker\u003c\/li\u003e\n  \u003cli\u003e20-amp, 120-volt AC rating for standard residential branch circuits\u003c\/li\u003e\n  \u003cli\u003e10 kA interrupt rating for reliable fault clearing\u003c\/li\u003e\n  \u003cli\u003ePlug-in connection for compatibility with THQL-style load centers\u003c\/li\u003e\n  \u003cli\u003eAccepts 14 to 8 AWG conductors\u003c\/li\u003e\n  \u003cli\u003e60 Hz frequency rating matched to North American electrical systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for THQL-compatible residential and light commercial panelboards accepting 1-pole plug-in circuit breakers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the panel and verify absence of voltage before handling any breaker or bussing. Follow the manufacturer wiring diagram for proper neutral and ground connections, as dual function breakers require a dedicated neutral pigtail connection to operate correctly. Do not exceed the conductor size range of 14 to 8 AWG on the load terminal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 20 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 120 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupt Rating\u003c\/strong\u003e: 10 kA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency Rating\u003c\/strong\u003e: 60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Plug-In\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 14 to 8 AWG\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ABB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: thql1120dx\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51620846240050,"sku":"THQL1120DX","price":79.92,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b6a2aff420cc20be75aa0ca488f0e59.jpg?v=1787347117","url":"https:\/\/voomisupply.com\/products\/abb-thql1120dx-dual-function-breaker-20a-1p-120v","provider":"Voomi Supply","version":"1.0","type":"link"}
