It is designed for residential and light commercial load centers where reliable overcurrent protection is required. The THHQL series is a thermal-magnetic breaker, meaning it trips on both sustained overloads and short-circuit faults. Licensed electricians install this breaker in panelboards during new construction, service upgrades, or branch circuit replacements. Its compact plug-on design allows straightforward installation without specialty tools.\u003c\/p\u003e\n\u003cp\u003eThe THHQL2120 fits residential and light commercial panelboards that accept THHQL-series plug-on breakers. It is a common choice for 240-volt branch circuits serving appliances such as HVAC equipment, dryers, water heaters, and subpanels. The two-pole configuration handles a single 240-volt circuit or two 120-volt circuits sharing a common disconnect. It is suited for indoor panel installations where the load demands a 20-amp double-pole breaker.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20-amp double-pole thermal-magnetic overcurrent protection\u003c\/li\u003e\n  \u003cli\u003e120\/240-volt AC rating for residential and light commercial branch circuits\u003c\/li\u003e\n  \u003cli\u003e22kAIC interrupting rating for fault current protection\u003c\/li\u003e\n  \u003cli\u003ePlug-on design for compatible load center installation\u003c\/li\u003e\n  \u003cli\u003eThermal-magnetic trip mechanism responds to both overload and short-circuit conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation breaker for panelboards accepting THHQL-series two-pole plug-on 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. Always de-energize and lock out the main disconnect before working inside a panelboard. Verify that the load center is listed as compatible with THHQL-series breakers before installation. Do not exceed the breaker or panel ampacity ratings for the circuit being protected.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 20 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 120\/240 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity\u003c\/strong\u003e: 22,000 amps (22kAIC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78316411749\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: THHQL2120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383417864498,"sku":"THHQL2120","price":295.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312676105.jpg?v=1782595942","url":"https:\/\/voomisupply.com\/products\/abb-thhql2120-two-pole-circuit-breaker-20a-120-240v","provider":"Voomi Supply","version":"1.0","type":"link"}
