It is designed for use in load centers and lighting panels where bolt-on bus connections are required. The thermal-magnetic trip mechanism provides overcurrent and short-circuit protection in both residential and commercial electrical distribution systems. Licensed electricians install this breaker as part of branch-circuit protection schemes governed by the National Electrical Code. Its compact one-inch-per-pole footprint makes it well suited for high-density panelboard layouts.\u003c\/p\u003e\n\u003cp\u003eThe THHQB1120 is intended for residential and commercial load centers and lighting panels that accept bolt-on style breakers. It is part of the broader Q Line breaker family, which is available in one-, two-, and three-pole configurations. This breaker can also be ordered with auxiliary contact or shunt trip accessories, and it is available in configurations rated for HID lighting applications, giving installers flexibility across a range of branch-circuit protection needs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20-amp rating with 22kA interrupting capacity for reliable short-circuit protection\u003c\/li\u003e\n  \u003cli\u003eBolt-on design for secure bus connection in load centers and lighting panels\u003c\/li\u003e\n  \u003cli\u003eOne-inch-per-pole compact footprint supports high-density panel installations\u003c\/li\u003e\n  \u003cli\u003eQuick-make and Quick-break mechanism for fast, consistent trip response\u003c\/li\u003e\n  \u003cli\u003eCommon trip bar design ensures coordinated multi-pole operation across the Q Line family\u003c\/li\u003e\n  \u003cli\u003eEasy-to-spot trip indication simplifies fault identification during service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a bolt-on replacement or new-installation breaker for load centers and lighting panels that accept Q Line bolt-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 and all applicable local codes. De-energize the panel and verify the absence of voltage before removing or installing any circuit breaker. Confirm that the panel accepts bolt-on style breakers before installation, as bolt-on and plug-in breakers are not interchangeable. Torque all wire terminations to the value specified on the panel nameplate or breaker label.\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\u003eInterrupting Capacity\u003c\/strong\u003e: 22kA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Bolt-on\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Q Line\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 783164118247\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: THHQB1120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383147299122,"sku":"THHQB1120","price":194.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312672036.png?v=1782588679","url":"https:\/\/voomisupply.com\/products\/abb-thhqb1120-bolt-on-circuit-breaker-20a-1-pole","provider":"Voomi Supply","version":"1.0","type":"link"}
