BQ2C100 - 100Amp Circuit Breaker

BQ2C100 - 100Amp Circuit Breaker

The Challenger BQ2C100 is a 2-pole, 100-amp molded case circuit breaker designed for use in compatible Type BQ panelboards and load centers. Rated for 120/240 VAC, it provides branch circuit protection for larger electrical loads and features a common-trip design that disconnects both poles during overload and short-circuit conditions.

In many installations, a 100-amp, 2-pole breaker is used for subpanel feeds, large HVAC equipment, electric heating systems, pumps, compressors, and other high-demand 240-volt applications. The bolt-on mounting design provides a secure connection within compatible panels, while the HACR rating allows use in heating, air conditioning, and refrigeration systems. Whether you're replacing a failed breaker or maintaining an existing Type BQ electrical system, the BQ2C100 offers the ratings and configuration needed to match the original equipment. Built to last, it remains a practical solution for keeping legacy electrical systems operating safely and efficiently.
