It is a plug-in device designed for connection to residential and commercial load centers and lighting panels. The THHQL1120 measures one inch wide per pole, making it a compact fit in standard panel configurations. It uses a Quick-make\/Quick-break mechanism for consistent, reliable operation and features easy-to-spot trip indication so technicians can identify a tripped breaker at a glance. Licensed electricians install this breaker during new construction, panel upgrades, and branch circuit replacements.\u003c\/p\u003e\n\u003cp\u003eThe THHQL1120 is suited for residential and light commercial applications where a plug-in, single-pole breaker is required in a Q Line compatible load center or lighting panel. Its compact one-inch-per-pole profile allows efficient use of panel space. The breaker can be ordered with auxiliary contact and shunt trip accessories for applications requiring remote monitoring or tripping capability. It is also available in configurations for HID lighting applications. This breaker fits into broader Q Line installations that may include 1, 2, and 3 pole breaker combinations within the same panel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThermal-magnetic trip mechanism provides overcurrent and short-circuit protection\u003c\/li\u003e\n  \u003cli\u003eQuick-make\/Quick-break mechanism ensures fast, reliable switching action\u003c\/li\u003e\n  \u003cli\u003eOne-inch-wide-per-pole compact design maximizes panel space efficiency\u003c\/li\u003e\n  \u003cli\u003eEasy-to-spot trip indication allows rapid visual identification of tripped state\u003c\/li\u003e\n  \u003cli\u003eCommon trip bar design for consistent multi-pole coordination across Q Line family\u003c\/li\u003e\n  \u003cli\u003eCompatible with auxiliary contact and shunt trip accessories for expanded functionality\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for plug-in connection to Q Line compatible load centers and lighting panels in residential and commercial installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the panel and verify the absence of voltage before handling any breaker or wiring. Confirm the load center is rated for Q Line plug-in breakers before installation. Do not exceed the breaker ampere rating for the connected branch circuit conductors.\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\/240 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrip Type\u003c\/strong\u003e: Thermal-magnetic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Plug-in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Per Pole\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 783164117394\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: THHQL1120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383787422002,"sku":"THHQL1120","price":44.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312671925.png?v=1782607464","url":"https:\/\/voomisupply.com\/products\/abb-thhql1120-single-pole-circuit-breaker-20a-120-240v","provider":"Voomi Supply","version":"1.0","type":"link"}
