Designed for maintenance, retrofit, and replacement projects, this breaker keeps power distribution safe and compliant without risking compatibility. Key specifications at a glance\n- Amperage: 100A\n- Poles: 4-Pole\n- Voltage: 600V\n- Part number: FD4100\n- Application: suited for installations that require simultaneous disconnection of all poles in a 3-phase, 4-wire system Why the FD4100 stands out\n- Exact fit for Eaton panel boards and configurations that demand a 4-pole, 100A, 600V protection device\n- Four-pole design ensures complete isolation of all conductors in multi-wire, three-phase circuits, enhancing safety during maintenance and fault isolation\n- Part-number precision: using FD4100 as your reference minimizes guesswork and reduces the risk of mismatched replacements Best-use scenarios\n- Retrofit projects in existing Eaton systems where the original protection device is a 4-pole 100A, 600V model\n- Replacement of aging or failed breakers in commercial or light industrial panels that require exact Eaton compatibility\n- Service upgrades that necessitate maintaining the same trip rating and voltage class to avoid cascading changes in protection schemes Compatibility and installation notes\n- Before ordering, verify that the panel and its labeling support a 4-pole, 100A, 600V device and that the FD4100 form factor matches your equipment\n- The FD4100 is the most reliable reference point for compatibility; cross-check the panel’s catalog number and listing to ensure seamless integration\n- Follow all safety guidelines and lockout\/tagout procedures during any replacement or retrofit work Practical benefits and outcomes\n- Consistent protection: preserves the designed protection scheme across all poles, reducing the risk of partial isolation during faults\n- Operational continuity: reliable replacement option minimizes downtime when a 4-pole breaker is required\n- Long-term reliability: engineered by Eaton to align with their panel systems, supporting predictable performance and easier maintenance planning If you’re planning a maintenance, retrofit, or replacement project that requires a precise, four-pole, 100A breaker for 600V service, the Eaton FD4100 delivers the compatibility, safety, and durability you expect from a trusted protection device. Confirm fit and ratings with the panel’s documentation, and use the FD4100 part number as your definitive reference to ensure a correct, hassle-free match.\u003c\/div\u003e","brand":"Eaton","offers":[{"title":"Default Title","offer_id":46427393720482,"sku":"FD4100","price":2105.0,"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\/eaton-fd4100-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
