With a 3-pole design and a 600V rating, this unit is engineered to safeguard your three-phase systems and keep critical equipment running smoothly.\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3-Pole\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 600V\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e RLM3400L\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Westinghouse\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eCompatibility note:\u003c\/strong\u003e The part number is the best reference for compatibility—confirm fit and ratings before ordering.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWhy this matters in real-world setups: a 3-pole breaker protects all conductors in a three-phase circuit, helping to prevent unbalanced loads and potential damage to motors, drives, and control gear. The 600V rating ensures reliable performance in industrial and commercial electrical environments where higher voltage distribution is in play. This is not just a drop-in part—it’s a deliberate choice to preserve your system’s protection scheme with the exact specifications your panels expect.\u003c\/p\u003e \u003cp\u003eIdeal use scenarios include:\u003c\/p\u003e\n\u003cul\u003e \u003cli\u003eMaintaining existing three-phase protection in service panels during routine maintenance.\u003c\/li\u003e \u003cli\u003eRetrofitting older installations to restore proper trip protection without changing the overall panel architecture.\u003c\/li\u003e \u003cli\u003eReplacing worn or failed breakers in compatible Westinghouse configurations to minimize downtime and ensure consistent protection profiles.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eHow to verify compatibility and ensure safe replacement:\u003c\/p\u003e\n\u003cul\u003e \u003cli\u003eUse the part number RLM3400L as the primary reference when checking catalogs, schematics, or service documentation.\u003c\/li\u003e \u003cli\u003eMatch the panel’s voltage rating (600V) and the three-pole arrangement to avoid mismatches in protection and wiring schemes.\u003c\/li\u003e \u003cli\u003eBefore purchase, cross-check any panel-specific requirements or approved breaker families to guarantee seamless interchangeability.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003ePractical considerations for installers and facility managers: this Westinghouse breaker is designed to integrate into systems that rely on precise, reliable three-phase protection. By selecting the exact RLM3400L model, you preserve the original protection logic, simplify future maintenance, and reduce the risk of compatibility issues during retrofits or replacements. If you’re building or upgrading a distribution panel that uses Westinghouse components, this 3-pole, 600V unit offers a confident path to continued safe operation and predictable performance.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Westinghouse","offers":[{"title":"Default Title","offer_id":46427400175778,"sku":"RLM3400L","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-rlm3400l-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
