If you’re replacing an aging breaker in a Westinghouse-compatible panel or upgrading a feeder from a lower capacity, this 125A, 3-pole unit is purpose-built to slot into the same footprint and interface with the same bus connections as the original equipment.\u003c\/p\u003e \u003ch3\u003eWhy it matters\u003c\/h3\u003e\n\u003cp\u003eUsing the exact Westinghouse 504C336G17 reference reduces the risk of misfit and compatibility issues that can happen with generic substitutes. The 125A rating gives you a balanced protection for high-demand loads while preserving selectivity within the panel’s overall protection scheme. The 415V rating ensures you stay within the electrical system’s voltage envelope, delivering reliable performance in regional power configurations that rely on 3-phase power.\u003c\/p\u003e \u003ch3\u003ePractical tips for installation and use\u003c\/h3\u003e\n\u003cp\u003eBefore purchasing, verify that your panel supports 3-pole breakers and a 415V nominal supply, and that the panel’s labeling aligns with the 504C336G17 part number. When replacing an existing breaker, document the original amperage, pole count, and voltage rating to confirm you’re maintaining the system’s protection philosophy. During installation, follow standard electrical safety practices and local codes, and test the circuit after re-energizing to confirm proper operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Westinghouse","offers":[{"title":"Default Title","offer_id":46427315929250,"sku":"504C336G17","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-504c336g17-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
