The part number MA3125 is the most reliable reference for compatibility, ensuring the breaker matches your panel’s bus configuration and overall protection scheme. With a 3‑pole design and a 125A rating, it’s well-suited for distributing balanced current across three phases in commercial or light industrial environments.\u003c\/p\u003e \u003cp\u003eImportant compatibility note: Confirm fit and ratings before ordering. The MA3125 should be used in systems that require a 3‑phase, 125A protection device within a 600V maximum rating. Using the exact part number as your compatibility reference minimizes downtime and reduces the risk of mismatches in panel replacements.\u003c\/p\u003e \u003cp\u003eIdeal use cases include:\u003c\/p\u003e\n\u003cul\u003e \u003cli\u003eRetrofits to bring older panels up to current 3‑phase protection standards\u003c\/li\u003e \u003cli\u003eReplacements for aging or malfunctioning breakers in commercial or light industrial facilities\u003c\/li\u003e \u003cli\u003eMaintenance projects where consistent trip thresholds across all three phases are essential\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003ePractical tips for a smooth upgrade: have the panel model and current wiring configuration on hand, verify the MA3125’s footprint and mounting arrangement aligns with your enclosure, and keep an on-hand stock of MA3125 units for rapid, planned maintenance. By aligning with the correct part number, you ensure reliable performance and safer electrical operation across your three-phase system.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Westinghouse","offers":[{"title":"Default Title","offer_id":46424425169058,"sku":"MA3125","price":310.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/westinghouse-ma3125-circuit-breaker-125a-3-pole-600v-382.webp?v=1789357432","url":"https:\/\/www.ampstate.com\/products\/westinghouse-ma3125-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
