BQ3D030 - 30Amp Circuit Breaker

BQ3D030 - 30 Amp Circuit Breaker

The BQ3D030 is a 30-amp, 3-pole bolt-on molded case circuit breaker designed for use in 240VAC three-phase electrical systems. Built on the BQ frame platform, it provides reliable overcurrent protection in compatible panelboards and load centers. With a 10kA interrupting rating at 240VAC and a 40°C calibration, this breaker is suited for standard commercial and industrial operating conditions. The bolt-on design helps ensure a secure connection to the bus bar, making it a practical choice when maintaining or servicing existing electrical distribution equipment. It is also HACR rated, allowing it to be used in heating, air conditioning, and refrigeration circuits where permitted by code. When replacing a breaker, matching the frame type, amperage, voltage, and interrupting capacity is critical. The BQ3D030 is designed for proper form, fit, and functional compatibility in panels that accept BQ frame breakers, helping maintain system integrity without modification.
