It is designed to protect branch circuits and feeder circuits from overcurrent and short-circuit faults in commercial and industrial electrical distribution systems. The THHQB series follows a bolt-on mounting configuration compatible with matching load centers and panelboards. Licensed electricians and electrical contractors handle installation and replacement of this device under NEC guidelines.\u003c\/p\u003e\n\u003cp\u003eThis circuit breaker is suited for use in commercial buildings, light industrial facilities, and multi-family residential applications where a robust, high-interrupt-capacity overcurrent protective device is required. The 70-amp rating makes it a common choice for sub-panel feeds, HVAC equipment disconnects, and larger branch circuit protection. Its 22kA interrupting rating addresses fault conditions found in service-entrance and feeder-level applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e70-amp continuous current rating for branch and feeder circuit protection\u003c\/li\u003e\n  \u003cli\u003e22kA short-circuit interrupting capacity for high-fault-current environments\u003c\/li\u003e\n  \u003cli\u003e3-pole configuration for three-phase distribution systems\u003c\/li\u003e\n  \u003cli\u003eMolded case construction provides durable, self-contained overcurrent protection\u003c\/li\u003e\n  \u003cli\u003eTHHQB series bolt-on design for secure panel mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit MCCB for panelboards and load centers accepting THHQB-series 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 (NEC) and applicable local codes. De-energize the panel and verify absence of voltage before removing or installing the breaker. Confirm the bus bar rating and panel compatibility before installation. Do not exceed the breaker ampere rating when sizing conductors and loads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmpere Rating\u003c\/strong\u003e: 70 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupt Capacity\u003c\/strong\u003e: 22kA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 3\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: 78316411864\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: THHQB32070\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383058923826,"sku":"THHQB32070","price":1231.7,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312676147.jpg?v=1782586906","url":"https:\/\/voomisupply.com\/products\/abb-thhqb32070-circuit-breaker-70a-22ka-3-pole","provider":"Voomi Supply","version":"1.0","type":"link"}
