BQCH2B040 - 40Amp Circuit Breaker

BQCH2B040 - 40Amp Circuit Breaker

When an electrical system requires a replacement breaker that matches existing equipment specifications, having the right fit matters. The BQCH2B040 is a 40 amp, 2-pole bolt-on molded case circuit breaker designed for applications that require a BQCH frame breaker with a 14kA interrupting rating at 480VAC. Whether you're performing routine maintenance, replacing a failed breaker, or restoring a system to its original configuration, this breaker provides the ratings and physical characteristics needed for compatible installations.

Its bolt-on design helps create a secure connection within approved electrical equipment, while the 2-pole configuration allows protection across two conductors in a single device. The HACR rating makes it suitable for heating, air conditioning, and refrigeration applications where that designation is required. Designed for operation in ambient temperatures up to 40°C (104°F), the BQCH2B040 is commonly found in commercial facilities, industrial environments, and other electrical distribution systems that depend on dependable circuit protection. Built to last, this breaker is intended to provide a form, fit, and functional replacement solution for compatible equipment without requiring changes to the existing setup.
