Operating at up to 600VAC, the Eaton FDC3100 delivers dependable long-time and instantaneous (LI) protection for industrial networks. This 3-pole, 100A molded case circuit breaker is a core component of the Series C F-Frame family. The unit mount design allows integration into Eaton switchboards, panelboards, and F-Frame enclosures. Featuring load side lugs, it replaces older FD3100 units requiring higher interrupt capacity. It features a 100kAIC rating at 480V and reverse feed capability.

Product FAQs
6 answers
What enclosures and panelboards are compatible with the FDC3100?
This breaker is designed for use in Eaton Series C panelboards, switchboards, motor control centers, and F-Frame enclosures.
What does the C in the FDC frame designation mean?
In Eaton Series C F-Frame nomenclature, the C indicates an extra-high interrupting capacity or current-limiting breaker. The FDC3100 provides up to 200kAIC at 240VAC and 100kAIC at 480VAC, which is significantly higher than standard FD or HFD models.
Can the FDC3100 be reverse fed?
Yes. Standard thermal-magnetic Series C F-Frame breakers like the FDC3100 do not have line and load markings and are suitable for reverse feed applications.
Can this breaker replace older Westinghouse FDC3100 models?
Yes. Eaton acquired the Westinghouse distribution equipment line. The modern Eaton or Cutler-Hammer FDC3100 is a direct replacement for older Westinghouse breakers with the exact same catalog number.
Is the FDC3100 suitable for DC applications?
Yes, it is rated for up to 250VDC with an interrupting capacity of 22kAIC. When used in DC systems, multiple poles may need to be wired in series depending on the specific voltage and grounding configuration.
Are the physical dimensions of the FDC3100 different from standard FD breakers?
No. All 3-pole Series C F-Frame breakers, including FD, HFD, and FDC models, share the exact same physical dimensions and mounting footprint.
