The 3‑pole design is ideal for three‑phase distribution, providing balanced protection across all phases and helping prevent partial system faults that can disrupt operations. With 240V rating, it’s built to handle typical industrial loads while maintaining dependable trip performance under short-circuit or overload conditions.\u003c\/p\u003e \u003ch3\u003eWho is this for?\u003c\/h3\u003e\n\u003cp\u003eElectrical maintenance teams, contractors, and panel builders working on Siemens-compatible panels will find this unit a precise match for existing QJ or equivalent configurations. It’s an excellent choice for upgrading or replacing aging breakers that require the exact 70A, 3‑pole, bolt-on form factor to restore full system protection.\u003c\/p\u003e \u003ch3\u003eHow to use and install\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, confirm fit and ratings against your panel. The part number QJ23B070HA01 is the best reference for compatibility—use it to verify mounting, trip characteristics, and overall fit within your enclosure. This breaker is intended for professional installation; always de-energize equipment and follow safety protocols, or consult a qualified electrician, when performing panel work.\u003c\/p\u003e \u003cp\u003eIn practice, this breaker supports reliable operation in scenarios such as motor circuits, feeders, and branch protections that require a sturdy, high-current, 3‑phase disconnect. When paired with appropriate busbars and enclosures, it helps maintain safe, efficient power distribution with minimal downtime during maintenance or upgrades.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":46427423670434,"sku":"QJ23B070HA01","price":510.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/master_generic_ad06fdd7-931c-4a09-bfbe-d05329579cd6.png?v=1765492978","url":"https:\/\/www.ampstate.com\/products\/siemens-qj23b070ha01-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
