B350H - 50Amp Circuit Breaker

B350H - 50Amp Circuit Breaker

The Siemens B350H 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 your circuits and connected equipment from overloads and short circuits that can cause equipment damage or unexpected downtime. This Type BLH breaker uses a thermal magnetic trip design that responds to both overload conditions and fault currents. With a 22kA interrupting rating, it is designed for applications where higher fault-current protection is needed. The bolt-on mounting style provides a secure fit in compatible panelboards and electrical distribution equipment, while the compact design helps conserve panel space. The Siemens B350H is commonly used in HVAC systems, machinery, control panels, and electrical distribution systems where dependable low-voltage circuit protection is required.
