CA3150W - 150Amp Circuit Breaker

CA3150W - 150 Amp Circuit Breaker

The CA3150W circuit breaker is a 3-pole, 150 amp molded case circuit breaker designed for dependable overcurrent protection in commercial and industrial power distribution systems. Built on a CA frame with a non-interchangeable trip unit, this breaker is rated for 10kA interrupting capacity at 240VAC, making it suitable for protecting branch circuits and feeders where moderate fault currents are present. Engineered for operation at 40°C, the CA3150W is a direct form, fit, and function replacement option for compatible legacy panelboards and switchgear assemblies. With no lugs installed, it provides flexibility for field-configured terminations based on your specific installation requirements. Designed with durability in mind, this molded case breaker delivers consistent protection for systems that demand dependable circuit interruption and long service life.
