B380HH - 80Amp Circuit Breaker

B380HH - 80Amp Circuit Breaker

The Siemens B380HH circuit breaker is made for commercial and industrial electrical systems where dependable protection is a priority. Rated at 80 amps and built for 240VAC applications, this 3-pole molded case circuit breaker helps protect your electrical equipment and distribution systems from overloads and short circuits that can interrupt operations or damage connected components.

Part of the Siemens HBL series, the B380HH features a thermal magnetic trip mechanism that responds to both overload conditions and fault currents. Its 65kA interrupting capacity makes it well suited for applications where higher fault-current protection is required. The bolt-on mounting design provides a secure connection in compatible panelboards and switchboards, while the compact construction helps you make installation and replacement work more manageable.

The Siemens B380HH is commonly used in commercial buildings, industrial facilities, manufacturing equipment, HVAC systems, and other three-phase electrical distribution applications where reliable circuit protection is needed every day.
