BQCH2B070 - 70Amp Circuit Breaker

BQCH2B070 - 70Amp Circuit Breaker

If you're looking for a BQCH2B070, you're likely replacing a breaker that's already in service or matching the requirements of existing equipment. This 70 amp, 2-pole bolt-on molded case circuit breaker is designed for systems that use a BQCH frame and require a 14kA interrupting rating at 480VAC. When the original equipment calls for those specifications, having the right breaker helps keep the installation consistent without changing the setup that's already in place.

The bolt-on mounting design allows the breaker to be installed in compatible equipment, while the 2-pole configuration is commonly used where both poles need to disconnect together. You'll often find breakers like this in commercial buildings, manufacturing facilities, warehouses, schools, and other properties that depend on electrical distribution equipment every day.

The BQCH2B070 is also HACR rated, making it suitable for heating, air conditioning, and refrigeration applications where that rating is specified. Rated for operation in 40°C ambient conditions, it can be used in a wide range of commercial and industrial environments. Whether you're replacing a failed breaker during maintenance or tracking down the correct part for an existing system, this breaker is built to last and designed to match the requirements of compatible equipment.
