BJ3225 - 225 Amp Circuit Breaker

BJ3225 - 225 Amp Circuit Breaker

The Eaton BJ3225 is a 225A, 3-pole thermal magnetic circuit breaker used as a main breaker in compatible Eaton BJ-series loadcenters. Rated for 240V AC systems, it features a common-trip design, plug-on mounting, and a 10 kAIC interrupting rating.

If you're matching an existing BJ-series installation, the BJ3225 is designed for loadcenters rated 150 amps or greater and accepts copper or aluminum conductors from #2 AWG to 300 kcmil. It is commonly used for breaker replacement, panel maintenance, and service equipment repairs where a 225A, 3-pole BJ-frame breaker is specified. Like many Eaton breakers installed throughout North America, it was built for long-term service when properly installed and maintained.
