BQD245 - 45Amp Circuit Breaker

BQD245 - 45Amp Circuit Breaker

The Siemens BQD245 is a 45-amp, 2-pole circuit breaker built for 480VAC electrical systems. It’s commonly used in panelboards, branch circuits, and lighting systems to protect wiring and equipment from overloads and short circuits. Its thermal magnetic trip reacts to slow overloads and sudden faults, keeping your circuits safe without interrupting normal operations unnecessarily.

Compact and panelboard-ready, the BQD245 is easy to install, and its low-tab connections make wiring simple. You’ll find it in offices, schools, healthcare facilities, warehouses, retail locations, and industrial plants where consistent 45-amp protection keeps systems running smoothly.
