CAH3125W - 125Amp Circuit Breaker

CAH3125W - 125 Amp Circuit Breaker

The CAH3125W molded case circuit breaker is a 3-pole, 125 amp breaker designed for dependable overcurrent protection in commercial and industrial power distribution systems. Built on the CAH frame and rated for 22kA interrupting capacity at 240VAC, this breaker is engineered to provide consistent thermal-magnetic protection in applications operating at up to 40°C. Its non-interchangeable trip unit ensures fixed, factory-set protection characteristics, making it a straightforward form, fit, and functional replacement for compatible CAH frame installations. With no lugs installed, it allows flexibility in meeting specific termination requirements. Designed to last and manufactured to meet established industry standards, the CAH3125W supports safe operation and continuity in existing electrical infrastructure.
