BQ2C040 - 40Amp Circuit Breaker

BQ2C040 - 40Amp Circuit Breaker

The Challenger BQ2C040 is a 2-pole, 40-amp molded case circuit breaker designed for you to use in compatible Type BQ panelboards and load centers. Rated for 120/240 VAC, it features a common-trip design that disconnects both poles during overload and short-circuit conditions.

A 40-amp, 2-pole breaker is commonly used on dedicated circuits serving air conditioners, heat pumps, water heaters, pumps, compressors, and other 240-volt equipment. The bolt-on mounting configuration provides a secure connection within the panel, while its HACR rating allows use in heating, air conditioning, and refrigeration applications. Designed to match the form, fit, and function of original Type BQ breakers, the BQ2C040 is a practical replacement for maintaining existing electrical systems. Built to last, it remains a dependable option for keeping your compatible equipment in service.
