Product FAQs

6 answers
Can I use the FD2100 to replace an older Westinghouse FD2100?

Yes. Eaton acquired the Westinghouse molded case circuit breaker line. The Eaton Series C FD2100 is a direct replacement for the legacy Westinghouse FD2100.

What is the difference between the FD2100, FDB2100, and HFD2100?

These breakers share the same physical F-Frame footprint but have different interrupting ratings at 480VAC. The FDB2100 is rated at 14kAIC, the FD2100 at 35kAIC, and the HFD2100 at 65kAIC.

What equipment is compatible with the FD2100 breaker?

This breaker is designed for use in Eaton and Cutler-Hammer Series C panelboards, switchboards, and motor control centers. It mounts directly to the chassis using a bolt-on connection.

Are the trip settings adjustable on the FD2100?

No. This breaker features a fixed thermal and fixed magnetic trip unit. It does not offer adjustable dials for long-time or instantaneous pickup settings.

Can the FD2100 be used in DC circuits?

Yes, this thermal magnetic breaker is rated for 250VDC applications with an interrupting capacity of 10kAIC.

What wire sizes do the standard lugs on the FD2100 accept?

The standard line and load lugs accommodate 14 AWG to 1/0 AWG copper or aluminum conductors.

    175amp molded case circuit breaker

    The breaker we purchased was as advertised. The breaker fit perfectly. We purchased reconditioned breaker and it seems to be working properly, accordingly to the golf course maintenance team that supervises the irrigation system.

    Next day shipping came quickly even though the 4th of July was coming.

    I wish it came with new installations hardware but that isn’t a deal breaker.
