BQD280 - 80Amp Circuit Breaker

BQD280 - 80Amp Circuit Breaker

The Siemens BQD280 is a 70-amp, 2-pole circuit breaker built for 480/277VAC systems. It protects your panelboards, branch circuits, and lighting systems from overloads and short circuits. The thermal magnetic trip reacts to both slow overloads and sudden faults, keeping wiring and equipment safe without causing unnecessary interruptions.

Designed for panelboard mounting, the BQD280 is compact and straightforward to install, with low-tab connections that make wiring simple. Rated for 14 kAIC, it handles fault currents safely.
