Product FAQs

6 answers
Can I use the Eaton FDB3030 to replace an older Westinghouse FDB3030 breaker?

Yes, the Eaton or Cutler-Hammer FDB3030 is a direct drop-in replacement for legacy Westinghouse FDB3030 circuit breakers. They share the exact same physical dimensions, mounting, and F-Frame design.

What types of equipment are compatible with the FDB3030?

This Series C F-Frame breaker is designed for installation in Eaton panelboards, switchboards, motor control centers, and dedicated F-Frame enclosures.

Does the FDB3030 include both line and load lugs?

By standard configuration, this bolt-on breaker is supplied with load side lugs only. The line side is designed to bolt directly to the panelboard bus.

Is the FDB3030 rated for HVAC or lighting applications?

Yes, this breaker is HACR rated for heating, air conditioning, and refrigeration equipment. Because it is in the 10 to 30 amp range, it is also rated for HID (High Intensity Discharge) lighting applications.

Can the FDB3030 be reverse fed?

Yes, Eaton Series C F-Frame circuit breakers like the FDB3030 are suitable for reverse feed applications.

What does the non-interchangeable trip unit mean for the FDB3030?

It indicates that the thermal-magnetic (LI) trip elements are fixed and factory sealed. The trip unit cannot be removed or swapped to change the amperage or trip curve of the breaker.

    Breaker was as expected.
