With a 45A rating and a 3‑pole configuration, it provides reliable overcurrent protection for demanding industrial equipment while supporting fast, field-friendly maintenance, retrofit, and replacement projects. When you need a trusted Eaton solution that aligns exactly with your panel specs, the FB3045 delivers.\u003c\/p\u003e \u003cp\u003eThis breaker is specified to match Eaton’s legacy and current panel architectures that require the FB3045 reference. The 3‑pole design ensures coordinated protection across all three phases, helping maintain balanced loads and predictable performance in motor drives, conveyors, pumps, and other three‑phase loads. Its bolt‑on mounting offers a secure, vibration-resistant connection ideal for environments where reliability matters most.\u003c\/p\u003e \u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 45A\u003c\/li\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\u003eMounting:\u003c\/strong\u003e Bolt-On\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWhy the Eaton FB3045 stands out\u003c\/h3\u003e\n\u003cp\u003eRather than a generic replacement, the FB3045 is purpose‑built for Eaton panel compatibility, reducing guesswork during retrofit or maintenance. Its bolt‑on design simplifies on-site installation and reduces downtime, while the 3‑pole arrangement provides synchronized trip protection across all phases—crucial for protecting motors and balanced 3‑phase systems from faults that could otherwise cause cascading outages.\u003c\/p\u003e \u003ch3\u003eIdeal use cases\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003ePanel upgrades and retrofits in industrial facilities requiring a 45A, 3‑pole, 600V breaker\u003c\/li\u003e \u003cli\u003eMaintenance replacements in service panels where exact FB3045 compatibility is specified\u003c\/li\u003e \u003cli\u003eNew installations or reconfigurations in three‑phase motor control circuits, conveyors, compressors, and pumps\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eInstallation and compatibility tips\u003c\/h3\u003e\n\u003cp\u003eAlways confirm fit and ratings before ordering. The part number, FB3045, is the best reference for compatibility with your Eaton panels and existing protection scheme. Before installation, verify that your system is designed for 600V, three‑phase operation and that bolt‑on mounting aligns with your panel’s mounting studs and bus configuration. Keep spares on hand for quick replacements to minimize downtime during routine maintenance or retrofit projects.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Eaton","offers":[{"title":"Default Title","offer_id":46427092353186,"sku":"FB3045","price":510.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/eaton-fb3045-circuit-breaker-45a-3-pole-600v-bolt-837.webp?v=1789671442","url":"https:\/\/www.ampstate.com\/products\/eaton-fb3045-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
