BQD6350 - 50Amp Circuit Breaker

BQD6350 - 50Amp Circuit Breaker

When you're working with a 347/600VAC distribution system, having the right breaker in place matters. The Siemens BQD6350 is a 3-pole, 50-amp molded case circuit breaker commonly used in commercial and industrial panelboards where three-phase power distribution is part of everyday operations. From lighting systems and feeder circuits to HVAC equipment and general power distribution, this breaker is designed for applications that require a Siemens BQD series breaker with a 50-amp rating.

The BQD6350 features a thermal-magnetic trip unit and a 10kA interrupting capacity, making it suitable for many standard power distribution applications.

You'll often find the BQD6350 in schools, office buildings, healthcare facilities, warehouses, manufacturing plants, and municipal properties operating on 347/600VAC electrical systems. For facilities already using Siemens panelboards, it provides a straightforward way to maintain compatibility while supporting the ongoing needs of the electrical distribution system.
