B280H - 80Amp Circuit Breaker

B280H - 80Amp Circuit Breaker

The Siemens B280H circuit breaker is built for your electrical systems that need dependable 80 amp overcurrent protection with a higher interrupting rating than standard breakers. Designed for 120/240VAC applications, this 2-pole breaker helps protect your circuits, panels, and connected equipment from overloads and short circuits in commercial, residential, and light industrial environments. Its 22 kA interrupting capacity makes the B280H a good fit for systems with higher available fault current, where added protection is important. The thermal magnetic trip design responds to both long-term overloads and sudden fault conditions, helping reduce the chance of damage to electrical equipment and wiring. The bolt-on mounting style also provides a secure fit in compatible Siemens panelboards and load centers, making installation and replacement work more straightforward.
