BQCH1B070 - 70Amp Circuit Breaker

BQCH1B070 - 70Amp Circuit Breaker

The BQCH1B070 is a 70 amp, single-pole bolt-on molded case circuit breaker used in electrical systems that require a BQCH frame breaker with a 14kA interrupting rating at 277VAC. If you're replacing an existing breaker, matching the original specifications is usually the most important part of the job. This model is intended for installations where those ratings and dimensions are already part of the system design.

You'll often find the BQCH1B070 in commercial buildings, schools, warehouses, manufacturing facilities, and other properties that rely on compatible electrical distribution equipment. It's commonly used in lighting panels, HVAC equipment, refrigeration systems, control panels, and branch circuits where a 70 amp single-pole breaker is required. The bolt-on mounting design helps ensure a secure installation in equipment built for this breaker style.
