BQ2C100 - 100Amp Circuit Breaker

BQ2C100 - 100 Amp Circuit Breaker

The BQ2C100 is a 2-pole, 100-amp bolt-on molded case circuit breaker designed for dependable overcurrent protection in 120/240VAC electrical distribution systems. Built on the BQ frame platform and rated at 10kA A.I.C., this breaker is well-suited for commercial and light industrial panelboard applications where form, fit, and function must match existing equipment. Its bolt-on mounting configuration provides a secure mechanical and electrical connection to the panelboard bus, helping maintain system integrity. HACR rated and calibrated for operation at 40°C, the BQ2C100 is built to last and intended for use in legacy systems requiring a compatible BQ frame replacement.
