Product FAQs
5 answersWhat equipment is compatible with the FB3025 breaker?
The FB3025 is a bolt-on F-frame breaker designed specifically for legacy Westinghouse CDP and FDP panelboards. It can also be installed in compatible Westinghouse motor control centers.
What is the modern replacement for the obsolete FB3025?
The FB3025 is a legacy component. When upgrading or replacing this unit, panel builders typically cross-reference it to the Eaton Series C FDB3025 or FD3025 molded case circuit breakers, which share the same F-frame footprint.
Is the FB3025 suitable for DC circuits?
Yes, this thermal-magnetic breaker carries a DC rating of 10kA at 250VDC, making it suitable for substantially non-inductive DC applications.
Does the FB3025 feature interchangeable trip units?
No, the FB3025 is built with a fixed thermal-magnetic trip unit. The trip elements are factory sealed and non-interchangeable, meaning the entire breaker must be replaced if different trip characteristics are required.
What are the wire gauge limits for the FB3025 terminals?
The standard lugs accommodate 14 AWG to 1/0 AWG conductors. These terminals are dual-rated for either copper or aluminum wiring.
