BJ3175 - 175 Amp Circuit Breaker

BJ3175 - 175 Amp Circuit Breaker

The Eaton BJ3175 is a 175A, 3-pole thermal magnetic circuit breaker for compatible Eaton BJ-series loadcenters. Rated for 240V AC systems, it is used as a main breaker in electrical distribution equipment requiring a 175-amp, three-pole configuration.

This breaker features a common-trip design, plug-on mounting, and a 10 kAIC interrupting rating. It accepts copper or aluminum conductors ranging from #2 AWG to 300 kcmil and is intended for use in loadcenters rated 150 amps and above. The BJ3175 is UL 489 listed and is frequently used for your breaker replacement, panel repairs, and service equipment maintenance where a compatible BJ-frame main breaker is required. Built to last, it continues to be used in many existing Eaton electrical systems.
