Rated for a continuous current of \u003cb\u003e400 amperes\u003c\/b\u003e at \u003cb\u003e250 volts\u003c\/b\u003e, this molded case circuit breaker ensures reliable system performance while managing heavy electrical loads commonly encountered in commercial and large facility environments. Its robust construction supports a maximum fault interruption capacity of \u003cb\u003e200,000 amperes\u003c\/b\u003e, allowing the equipment to safely clear dangerous short-circuit conditions without damaging upstream infrastructure or compromising the physical integrity of the broader electrical network and connected machinery. Technicians installing this component in equivalent service panels must ensure the enclosure accepts the \u003cb\u003eQMQB\u003c\/b\u003e frame specification to guarantee proper fit, secure mounting, and continued functionality for heavy-duty branch circuit implementations found within standard maintenance schedules for electrical systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"FPE","offers":[{"title":"New","offer_id":51691078517038,"sku":null,"price":1264.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_596ca66b-fb1a-42e5-8c12-e62d62f059a1.jpg?v=1769879904","url":"https:\/\/plgautomation.com\/products\/federal-pacific-electric-qmqb4032h-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
