Product FAQs
6 answersCan I use the Eaton FDB2150L to replace an older Westinghouse FDB2150L?
Yes. Eaton acquired the Westinghouse distribution equipment line, and they share the exact same Series C F-Frame architecture. The FDB2150L is a direct, drop-in replacement for legacy Westinghouse and Cutler-Hammer breakers that share the same catalog number.
What does the "L" suffix in the FDB2150L catalog number indicate?
The "L" indicates that the circuit breaker is supplied with factory-installed line and load lugs. Breakers without this suffix may require you to purchase lug kits separately or are intended for different mounting configurations.
Is the FDB2150L circuit breaker suitable for reverse-feed applications?
Yes. Because it utilizes a standard thermal-magnetic trip unit without dedicated line and load directional markings, this F-Frame breaker is capable of being reverse fed in your distribution system.
Does the FDB2150L carry an HACR rating for HVAC equipment?
Yes, this Series C breaker is HACR rated. It is tested and approved to handle the specific inrush currents and operational demands of heating, air conditioning, and refrigeration circuits.
Can I adjust the trip settings on the FDB2150L?
No. This breaker features a non-interchangeable trip unit with fixed thermal and fixed magnetic (LI) settings. It will trip at a predetermined curve for its 150-amp rating and cannot be field-adjusted.
Can I install this 2-pole breaker in a 3-phase panelboard?
Yes, a 2-pole breaker like the FDB2150L can be installed in a 3-phase panelboard or enclosure, but it will only draw power from and protect two of the three phases. It is commonly used to feed single-phase loads derived from a 3-phase system.
