B330H - 30Amp Circuit Breaker

B330H - 30Amp Circuit Breaker

The Siemens B330H circuit breaker is designed for your three-phase electrical systems that require dependable protection and higher interrupting capacity. Rated at 30 amps for 240V applications, this Type BLH breaker helps protect your electrical equipment, wiring, and panels from overloads and short circuits in commercial and industrial settings. Its 22kA interrupting rating makes it a good fit for systems with higher available fault current levels. The thermal magnetic trip mechanism responds to both overload conditions and sudden faults to help maintain safe electrical operation and reduce the risk of equipment damage. The bolt-on mounting style provides a secure connection in compatible Siemens panelboards and distribution equipment. Its compact size also works well in electrical panels where installation space may be limited.
