B350HH - 50Amp Circuit Breaker

B350HH - 50Amp Circuit Breaker

The Siemens B350HH circuit breaker is designed for commercial and industrial electrical systems that require higher fault-current protection. Rated at 50 amps and 240VAC, this 3-pole molded case circuit breaker helps protect your wiring and connected equipment from overloads and short circuits that can lead to equipment damage or downtime. This Type HBL breaker uses a thermal magnetic trip mechanism that responds to overloads and fault conditions. Its 65kA interrupting rating makes it suitable for applications where higher available fault current protection is needed. The bolt-on mounting design provides a secure fit in compatible panelboards and electrical distribution equipment, while the compact design helps you conserve panel space. The Siemens B350HH is commonly used in manufacturing facilities, HVAC systems, motor control equipment, and commercial power distribution systems where dependable low-voltage circuit protection is important for daily operation.
