BQD150 - 50Amp Circuit Breaker

BQD150 - 50Amp Circuit Breaker

The Siemens BQD150 is a 50-amp, single-pole breaker that protects circuits from overloads and short circuits. It fits neatly in panelboards and works in tight spaces. The thermal magnetic trip responds to both slow overloads and sudden faults, keeping your wiring and equipment safe without unnecessary shutdowns. Rated for 277VAC with a 14 kAIC interrupting capacity, the BQD150 is commonly used in lighting panels, control panels, and low-voltage systems. Its molded case is sturdy, and low-tab connections make installation quick and simple. Electricians and maintenance teams trust it for everyday protection that keeps your systems running smoothly.
