BQD250 - 50Amp Circuit Breaker

BQD250 - 50Amp Circuit Breaker

The Siemens BQD250 is a 50-amp, 2-pole breaker for 480VAC circuits. You’ll often find it in panelboards, branch circuits, and lighting systems where protection from overloads and short circuits is needed. Its thermal magnetic trip reacts to both gradual overloads and sudden faults, keeping wiring and equipment safe without causing unnecessary interruptions.

It’s compact and panelboard-ready, with low-tab connections that make wiring simple. It’s a reliable choice in offices, schools, warehouses, healthcare facilities, retail locations, and industrial plants where consistent 50-amp protection is important.
