CA3175W - 175Amp Circuit Breaker

CA3175W - 175 Amp Circuit Breaker

The CA3175W molded case circuit breaker is a 3-pole, 175 amp breaker designed to provide dependable overcurrent protection in commercial and industrial electrical distribution systems. Built on a CA frame and rated for 10kA at 240VAC, this breaker is engineered for consistent thermal-magnetic protection in applications operating at up to 40°C. With a non-interchangeable trip unit, the CA3175W maintains fixed trip characteristics to help ensure stable and predictable circuit protection. This unit is supplied without lugs installed, allowing qualified professionals to configure terminations according to project requirements. Designed to meet the demands of existing panel and switchgear installations, the CA3175W offers the proper form, fit, and function required for maintaining legacy electrical systems.
