It provides overcurrent and short-circuit protection for branch circuits in load centers and panelboards. The THQL series uses a thermal-magnetic trip mechanism that responds to both sustained overloads and instantaneous fault currents. Licensed electricians install this breaker during new construction, panel upgrades, and circuit additions. It fits standard THQL-compatible load centers and is a common replacement in residential electrical panels.\u003c\/p\u003e\n\u003cp\u003eThe THQL2120 is suited for residential load centers and light commercial panelboards requiring a 2-pole, 20-amp branch circuit breaker. Typical applications include 240-volt appliance circuits, HVAC disconnect protection, and general-purpose dual-pole branch circuits. It is designed to be installed in load centers that accept THQL-series breakers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-pole configuration provides 240-volt branch circuit protection\u003c\/li\u003e\n  \u003cli\u003eThermal-magnetic trip mechanism responds to both overload and short-circuit conditions\u003c\/li\u003e\n  \u003cli\u003eStandard THQL footprint for compatible load center installation\u003c\/li\u003e\n  \u003cli\u003eSingle-phase 120\/240 volt rated for residential and light commercial panels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for residential and light commercial load centers accepting THQL-series 2-pole 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 applicable local codes. Always de-energize the panel and verify absence of voltage with a meter before handling any breaker or bus connection. Do not install a breaker into a panel that is not rated for THQL-series devices. Confirm the panel's main breaker is off and that the new breaker is fully seated on the bus bar before restoring power.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoles\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 120\/240 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 783164012910\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: THQL2120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383811440946,"sku":"THQL2120","price":28.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312673554.png?v=1782608065","url":"https:\/\/voomisupply.com\/products\/abb-thql2120-2-pole-circuit-breaker-20a-120-240v","provider":"Voomi Supply","version":"1.0","type":"link"}
