CA3125W - 125Amp Circuit Breaker

CA3125W - 125 Amp Circuit Breaker

The CA3125W circuit breaker is a 3-pole, 125 amp molded case circuit breaker designed for dependable overcurrent protection in commercial and industrial power distribution systems operating at up to 240VAC. Built on the CA frame platform, this breaker features a non-interchangeable trip unit calibrated for operation in 40°C ambient conditions, helping protect conductors and connected equipment from overloads and short circuits. With a 10kA interrupting capacity at 240VAC, the CA3125W is engineered to meet the functional demands of legacy electrical panels and distribution equipment where form, fit, and rating compatibility are critical. No lugs are installed, allowing qualified professionals to configure terminations according to project requirements. Constructed to withstand everyday electrical stresses, this breaker is built to last and provide consistent circuit protection in properly rated systems.
