BQD6250 - 50Amp Circuit Breaker

BQD6250 - 50Amp Circuit Breaker

The Siemens BQD6250 is a 2-pole, 50-amp molded case circuit breaker designed for use in 347/600VAC electrical distribution systems. Commonly found in commercial and industrial installations, this breaker helps protect your circuits and connected equipment from overloads and short circuits while providing the dependable performance expected from Siemens circuit protection products.

Built with a thermal-magnetic trip unit, the BQD6250 responds to both sustained overload conditions and higher fault currents. That makes it a practical choice for panelboards serving lighting systems, feeder circuits, and other distribution equipment where reliable overcurrent protection is essential. Its panelboard-mount design and compact footprint also make it well suited for new installations, system upgrades, and replacement projects.

Whether you're installing it in a commercial building, manufacturing facility, school, healthcare facility, or office complex, this breaker provides the protection needed to help keep electrical systems operating safely and efficiently.
