With a 70A rating and a compact 2-pole configuration, this breaker provides reliable overcurrent protection for heavy-duty equipment while ensuring both hot legs shut off together for safer, more predictable trips.\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e QB70\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eCurrent rating:\u003c\/strong\u003e 70 A\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 2\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVoltage rating:\u003c\/strong\u003e 240 V\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eThe two-pole design is key for 240V circuits, guaranteeing simultaneous disconnection of both live conductors during an overload or short-circuit event. This reduces arc exposure and protects downstream equipment, making the QB70 ideal for industrial feeders, motor circuits, conveyor lines, and critical panel protections where dependable shutdowns matter most.\u003c\/p\u003e \u003cul\u003e \u003cli\u003eFits 240V applications in manufacturing facilities, warehouses, and large workshops\u003c\/li\u003e \u003cli\u003eSuitable as a protective device in industrial control panels and distribution panels\u003c\/li\u003e \u003cli\u003eProvides clear, immediate interruption when electrical irregularities occur, helping minimize damage to connected machinery\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWhy choose the Industrial QB70? It pairs a straightforward, robust protection mechanism with a dedicated 70 A capacity, tailored for mid- to high-demand 240V circuits. Its 2-pole construction delivers safer operation by interrupting both hot legs, reducing the risk of residual voltage on sensitive loads. For installations upgrading existing equipment or planning new builds, the QB70 offers a dependable, easy-to-specify solution that aligns with typical industrial power distribution needs.\u003c\/p\u003e \u003cp\u003ePractical tips for use: verify compatibility with your panel and enclosure, ensure proper mounting, and replace only with the same part number to preserve protection characteristics. For facilities running heavier electrical loads on 240V systems, the QB70 provides a clear, reliable line of defense against overloads and short circuits, helping keep production running smoothly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Industrial","offers":[{"title":"Default Title","offer_id":46423071096994,"sku":"QB70","price":510.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/industrial-qb70-70a-2-pole-240-v-circuit-breaker-860.webp?v=1789267243","url":"https:\/\/www.ampstate.com\/products\/industrial-qb70","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
