Description
Designed for industrial distribution, the Eaton FB3010 is a 10A, three-pole molded case circuit breaker. It features a fixed thermal-magnetic trip mechanism and includes line and load lugs. This legacy component is an exact replacement for older Westinghouse panelboards and motor control centers. It eliminates retrofitting by substituting the discontinued FDB3010 and FD3010 models. Rated for 600VAC, it incorporates AB De-Ion arc extinction to safely clear electrical faults.Specifications

Product FAQs
6 answersWhat types of enclosures or panels are compatible with the FB3010?
The FB3010 is an F-Frame molded case circuit breaker designed primarily for use in legacy Westinghouse panelboards and Motor Control Centers.
Can the FB3010 be used in direct current (DC) applications?
Yes, this breaker is rated for DC systems. It provides an interrupting capacity of 10kA at 250VDC.
Are the trip settings on the FB3010 adjustable?
No, this breaker features a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous (LI) protection without field adjustability.
What wire sizes and materials are compatible with the FB3010 lugs?
The standard lugs on this breaker accept wire gauges from 14 AWG up to 2 AWG. They are rated for both copper (Cu) and aluminum (Al) conductors.
How is the FB3010 installed into a panelboard?
It utilizes a bolt-on connection. The breaker must be bolted directly to the panelboard bus, which provides a secure and reliable mechanical and electrical connection compared to plug-on designs.
Is the FB3010 still manufactured by Westinghouse?
Westinghouse circuit breakers were acquired by Eaton Cutler-Hammer. The FB3010 is now considered a legacy F-Frame breaker, but it remains available for maintaining and expanding existing Westinghouse and Eaton systems.
