BQD120 - 20Amp Circuit Breaker Description
BQD120 - 20Amp Circuit Breaker
Looking for a BQD120? You're probably replacing an existing breaker or confirming a part number before starting a job. This 20 amp, single-pole Siemens circuit breaker is part of the BQD series and is rated for 277VAC with a 14kA interrupting capacity. If those specifications match what's already installed, you're on the right track.
The BQD120 uses a thermal-magnetic trip unit and is designed for compatible Siemens panelboard applications. It's commonly found protecting lighting and branch circuits in commercial buildings where 277-volt systems are used.
Whether you're servicing a school, office building, warehouse, healthcare facility, or retail property, matching the original breaker is often the easiest way to keep a project moving. The BQD120 is built to last and intended for equipment that requires a 20 amp, 1-pole, 277VAC breaker with a 14kA interrupting rating.
