Product FAQs

5 answers
Can the Eaton FDB2020 replace an older Westinghouse FDB2020?

Yes. Eaton acquired the Westinghouse distribution equipment division. The current Eaton or Cutler-Hammer FDB2020 is a direct, exact replacement for legacy Westinghouse FDB2020 circuit breakers.

What is the difference between Eaton FDB, FD, and HFD circuit breakers?

The prefix designates the interrupting capacity of the Series C F-frame breaker. The FDB is the standard tier, rated at 14kAIC at 480VAC. FD models offer a higher interrupting capacity, and HFD models provide the highest interrupting ratings in the F-frame family.

Is the FDB2020 suitable for reverse feed applications?

Yes. Eaton Series C F-frame thermal magnetic circuit breakers, including the FDB2020, are suitable for reverse feed use.

What equipment is compatible with the FDB2020 breaker?

This F-frame breaker is designed for bolt-on installation in Eaton Series C panelboards, switchboards, and motor control centers. It is also backward compatible with legacy Cutler-Hammer and Westinghouse enclosures designed for F-frame breakers.

Is the FDB2020 HACR rated?

Yes. All Eaton Series C F-frame circuit breakers carry an HACR rating, making them suitable for heating, air conditioning, and refrigeration applications.

    Breaker was as expected.

    Breaker was clean, you could not tell it was used.
