Product FAQs
5 answers
Can the Eaton FDC3110L replace an older Westinghouse FDC3110L?
Yes. Eaton acquired the Westinghouse distribution equipment business in the 1990s. The current Eaton Cutler-Hammer FDC3110L is an exact, direct replacement for the legacy Westinghouse breaker with the same catalog number.
Is the FDC3110L suitable for reverse feed applications?
Yes. Eaton Series C F-frame thermal magnetic circuit breakers are suitable for reverse feed use because they do not have specific line and load directional restrictions.
What is the difference between Eaton FD, HFD, and FDC circuit breakers?
These prefixes indicate the interrupting capacity of the Series C F-frame breakers. FD is the standard rating, HFD is the high interrupting rating, and FDC provides the extra-high interrupting capacity, which is rated at 100kA at 480VAC for this model.
Is the FDC3110L HACR rated?
Yes. All Eaton Series C F-frame circuit breakers are HACR rated for use with heating, air conditioning, and refrigeration equipment.
Can the trip unit on the FDC3110L be swapped to change the amperage?
No. The FDC3110L features a non-interchangeable trip unit. The thermal and magnetic trip functions are fixed at the factory and cannot be modified or replaced in the field.
