Its three‑pole design is particularly important in environments with balanced loads across three phases, where coordinated tripping reduces risk to equipment and personnel.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eWho this is for\u003c\/strong\u003e: Maintenance teams, retrofit projects, and replacement efforts in industrial facilities, manufacturing lines, and commercial power distribution setups that run on 415V three‑phase networks and require a 400A protective device.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eHow it compares to other options\u003c\/strong\u003e: When you need protection for a three‑phase circuit at 415V with a 400A capacity, a three‑pole unit like this Westinghouse model offers coordinated phase protection that single- or two‑pole breakers cannot provide. It’s specifically chosen when panel compatibility and spec fidelity are paramount, reducing downtime and the risk of mismatches during upgrades or service work.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003ePractical tips\u003c\/strong\u003e: Before purchasing, verify your panel’s model and the 315C043G23 designation to ensure a perfect match. When installing, follow standard electrical safety procedures and consult your panel’s labeling to confirm recommended breakers for your configuration. Keeping a spare compatible unit on hand can significantly shorten service windows during planned maintenance or retrofits.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Westinghouse","offers":[{"title":"Default Title","offer_id":46427328053410,"sku":"315C043G23","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\/westinghouse-315c043g23-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
