BR350 - 50 Amp Circuit Breaker

BR350 - 50 Amp Circuit Breaker

If you're replacing a 50 Amp, 3-pole breaker in an Eaton Type BR panel, the BR350 is designed for that application. This thermal-magnetic circuit breaker is used in compatible Eaton Type BR loadcenters and is commonly installed on three-phase circuits serving HVAC equipment, pumps, compressors, motors, machinery, and other electrical loads that require a 50 Amp breaker.

Rated for 240V AC systems, the BR350 carries a 10 kAIC interrupting rating and accepts #14–4 AWG copper or aluminum conductors. You'll often find this breaker in commercial buildings, workshops, agricultural facilities, mechanical rooms, and light industrial environments where three-phase power distribution is required. For most electricians and facility maintenance teams, selecting the BR350 comes down to matching the panel series, amperage rating, and pole configuration already specified for the installation.

Where It Works Best

• The Eaton BR350 is commonly installed in commercial buildings, warehouses, workshops, agricultural facilities, mechanical rooms, and light industrial environments where three-phase circuit protection is required. You'll often see it protecting HVAC equipment, pumps, compressors, motor-driven machinery, control panels, and other electrical loads that require a 50 Amp, 3-pole breaker. It is also frequently used when replacing an existing breaker in a compatible Eaton Type BR loadcenter.
