It provides overcurrent and short-circuit protection in residential, commercial, and light industrial electrical distribution systems. The THHQB series is designed for installation in compatible load centers and panelboards where reliable branch-circuit protection is required. Licensed electricians install this breaker as part of service panel work, branch circuit additions, or equipment protection upgrades. The 100A rating makes it suitable for high-draw branch circuits and subpanel feed applications.\u003c\/p\u003e\n\u003cp\u003eThe THHQB21100 is suited for use in load centers and distribution panels requiring a 2-pole breaker with a 100A continuous rating. Its 22kA interrupt rating supports installations where available fault current demands a higher-rated protective device. Typical applications include commercial tenant buildouts, residential service upgrades, and industrial feeder protection where panel space and fault current levels must both be addressed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e100A continuous current rating for high-demand branch and feeder circuits\u003c\/li\u003e\n  \u003cli\u003e22kA interrupting capacity for installations with elevated available fault current\u003c\/li\u003e\n  \u003cli\u003e2-pole configuration for 240-volt branch circuit protection\u003c\/li\u003e\n  \u003cli\u003eTHHQB series design for compatibility with supported panelboard and load center applications\u003c\/li\u003e\n  \u003cli\u003eProvides both overcurrent and short-circuit protection in a single device\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-fit 2-pole miniature circuit breaker for panelboards and load centers that accept the THHQB breaker series.\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 and lock out the panel before removing or installing any breaker. Verify that the available fault current at the installation point does not exceed the 22kA interrupting rating of this device. Confirm panelboard compatibility with the THHQB series before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 100 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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: THHQB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78316413498\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: THHQB21100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383769891122,"sku":"THHQB21100","price":185.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678513.jpg?v=1782606913","url":"https:\/\/voomisupply.com\/products\/abb-thhqb21100-miniature-circuit-breaker-100a-22ka","provider":"Voomi Supply","version":"1.0","type":"link"}
