Product FAQs
6 answersCan I use the Eaton FDB3090L to replace an older Westinghouse FDB3090L?
Yes. Eaton acquired the Westinghouse distribution equipment line. The current Series C F-frame breakers are direct replacements for legacy Westinghouse models sharing the same catalog number.
What does the L suffix in the FDB3090L catalog number indicate?
The L indicates that the breaker is factory-equipped with both line and load side lug terminals. These lugs accept 14 to 1/0 AWG copper or aluminum wire.

This unit mount breaker is designed to bolt directly into compatible Eaton Series C panelboards, switchboards, and motor control centers.

Yes, in addition to its AC ratings, this breaker is rated for up to 250VDC with an interrupting capacity of 10 kAIC.
Can the trip settings on the FDB3090L be adjusted in the field?
No. This breaker features a non-interchangeable thermal magnetic trip unit with fixed long-time and fixed instantaneous trip functions.
