B380H - 80Amp Circuit Breaker

B380H - 80Amp Circuit Breaker

The Siemens B380H circuit breaker is built for commercial and industrial electrical systems that need reliable protection without overcomplicating the job. Rated at 80 amps and designed for 240VAC systems, this 3-pole breaker helps protect your equipment and electrical distribution systems from overloads and short circuits that can lead to downtime or damaged components.

As part of the Siemens BLH series, the B380H uses a thermal magnetic trip mechanism that responds to both overload conditions and fault currents. Its 22kA interrupting capacity makes it a good fit for applications where higher fault-current protection is needed. The bolt-on mounting design provides a secure connection in compatible panelboards and switchboards, while the compact size helps make installation and replacement work easier. 

The Siemens B380H is commonly used in commercial buildings, industrial facilities, HVAC equipment, and three-phase electrical systems where dependable circuit protection is important for everyday operation.
