B350 - 50Amp Circuit Breaker Description
B350 - 50Amp Circuit Breaker
The Siemens B350 circuit breaker is designed to protect your three-phase electrical systems in commercial and industrial applications. Rated at 50 amps and 240VAC, this molded case circuit breaker helps protect circuits and equipment from overloads and short circuits that can damage electrical systems or interrupt operation. This Type BL breaker uses a thermal magnetic trip design that responds to both overload conditions and fault currents. The bolt-on mounting style provides a secure fit in compatible panelboards and distribution equipment, while the compact design helps conserve panel space. With a 10kA interrupting rating, the Siemens B350 is commonly used in HVAC systems, control panels, machinery, and general electrical distribution applications where dependable low-voltage circuit protection is needed.
