Rated at 40A, this breaker is designed for maintenance, retrofit, and replacement projects where exact specifications matter and reliable fault protection is non-negotiable. Built to integrate with Eaton systems and compatible panels, the FDC4040L delivers consistent performance when uptime and safety are paramount.\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 40A\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 4-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 FDC4040L\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWhy this configuration matters: a 4-pole design is well-suited for 3-phase systems with a neutral, allowing comprehensive protection across all conductors and simplifying panel wiring during upgrades or replacements. The FDC4040L is a precise reference point for compatibility, making it a trusted choice when you need to match an existing Eaton installation or when a project specification calls for Eaton-branded components.\u003c\/p\u003e \u003cp\u003eThoughtful use scenarios include upgrading legacy 4-pole assemblies in 600V distribution panels, replacing a failed 40A breaker in manufacturing or processing lines, and retrofitting control cabinets to meet updated electrical standards. When ordering, rely on the part number FDC4040L as your best-fit reference to ensure a seamless fit with your current equipment and any panels that specify this Eaton model.\u003c\/p\u003e \u003cp\u003ePractical installation notes: verify fit and ratings before ordering, and match the exact part number to maintain system integrity. This focused approach helps you avoid mismatches and ensures your circuit protection aligns with your existing electrical architecture, improving safety, reliability, and long-term performance.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Eaton","offers":[{"title":"Default Title","offer_id":46426172915874,"sku":"FDC4040L","price":2010.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/eaton-fdc4040l-circuit-breaker-40a-4-pole-600v-805.webp?v=1789527297","url":"https:\/\/www.ampstate.com\/products\/eaton-fdc4040l-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
