Product FAQs

8 answers
What is the difference between the FDB2150, FD2150, and HFD2150?

These breakers share the same physical dimensions and F-Frame footprint but have different interrupting ratings. The FDB2150 is rated at 14kAIC at 480VAC, the FD2150 is rated at 35kAIC at 480VAC, and the HFD2150 is rated at 65kAIC at 480VAC.

Can I use the Eaton FDB2150 to replace an older Westinghouse FDB2150?

Yes, Eaton acquired the Westinghouse and Cutler-Hammer breaker lines. The current Eaton FDB2150 is a direct, drop-in replacement for legacy Westinghouse and Cutler-Hammer FDB breakers.

What is the modern Power Defense equivalent for the FDB2150?

Does the mounting orientation of the FDB2150 affect its performance?

No, Eaton Series C F-Frame breakers can be mounted in horizontal or vertical orientations without affecting their thermal-magnetic trip characteristics.

Are lugs included with the FDB2150, and what wire sizes do they accept?

Standard load-side lugs are typically included and accept 4 AWG to 4/0 AWG copper or aluminum wire.

Is the FDB2150 rated for use in DC circuits?

Yes, this breaker is rated for up to 250VDC with an interrupting capacity of 10kAIC, making it suitable for specific direct current applications.
