BQCH1B020 - 20Amp Circuit Breaker

BQCH1B020 - 20 Amp Circuit Breaker

The BQCH1B020 circuit breaker is a 1-pole, 20-amp molded case circuit breaker designed for dependable overcurrent protection in commercial and industrial distribution panels using the BQCH frame type. Rated at 14kA interrupting capacity at 277VAC, this bolt-on breaker is built to help protect branch circuits from overloads and short circuits while maintaining proper fit and function within compatible panelboards. With its HACR rating and 40°C calibration, the BQCH1B020 is well-suited for applications involving heating, air conditioning, and refrigeration equipment, as well as standard lighting and receptacle circuits. Its bolt-on mounting style ensures a secure mechanical and electrical connection in panel assemblies designed for BQCH series breakers. Built to last and manufactured to meet industry standards, this breaker offers a reliable solution for maintaining existing electrical systems and replacing worn or damaged units with the correct form, fit, and function.
