BQCH3B040 - 40Amp Circuit Breaker

BQCH3B040 - 40Amp Circuit Breaker

If you're searching for a BQCH3B040, you're probably looking to replace an existing breaker or match the specifications of equipment already in service. This 40 amp, 3-pole bolt-on molded case circuit breaker is designed for applications that require a BQCH frame and a 14kA interrupting rating at 480VAC. When the frame type, amperage, and mounting style match what's already installed, finding the right replacement becomes much simpler.

This breaker is also HACR rated, making it suitable for heating, air conditioning, and refrigeration applications where that rating is required. With a 40°C ambient rating, it can be used in a variety of operating environments. Whether you're replacing a failed breaker, completing routine maintenance, or tracking down the correct part for an existing installation, the BQCH3B040 is built to last and designed for equipment that calls for these exact specifications.
