Eaton | FD4100 | Circuit Breaker | 100A | 4-Pole | 600V

Eaton FD4100 100A 4-Pole 600V circuit breaker is built to stand up to demanding electrical environments, delivering reliable overcurrent protection for 3-phase systems where a four-pole device with a neutral disconnect is required. Designed for maintenance, retrofit, and replacement projects, this breaker keeps power distribution safe and compliant without risking compatibility. Key specifications at a glance - Amperage: 100A - Poles: 4-Pole - Voltage: 600V - Part number: FD4100 - Application: suited for installations that require simultaneous disconnection of all poles in a 3-phase, 4-wire system Why the FD4100 stands out - Exact fit for Eaton panel boards and configurations that demand a 4-pole, 100A, 600V protection device - Four-pole design ensures complete isolation of all conductors in multi-wire, three-phase circuits, enhancing safety during maintenance and fault isolation - Part-number precision: using FD4100 as your reference minimizes guesswork and reduces the risk of mismatched replacements Best-use scenarios - Retrofit projects in existing Eaton systems where the original protection device is a 4-pole 100A, 600V model - Replacement of aging or failed breakers in commercial or light industrial panels that require exact Eaton compatibility - Service upgrades that necessitate maintaining the same trip rating and voltage class to avoid cascading changes in protection schemes Compatibility and installation notes - 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 - The FD4100 is the most reliable reference point for compatibility; cross-check the panel’s catalog number and listing to ensure seamless integration - Follow all safety guidelines and lockout/tagout procedures during any replacement or retrofit work Practical benefits and outcomes - Consistent protection: preserves the designed protection scheme across all poles, reducing the risk of partial isolation during faults - Operational continuity: reliable replacement option minimizes downtime when a 4-pole breaker is required - 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.
