CAH3150 - 150Amp Circuit Breaker

CAH3150 - 150 Amp Circuit Breaker

The CAH3150 molded case circuit breaker is a 150-amp, 3-pole breaker designed for dependable overcurrent protection in commercial and industrial electrical distribution systems. Built on the CAH frame and rated at 22kA interrupting capacity at 240VAC, this breaker is engineered to provide reliable protection against overloads and short circuits in 40°C environments. With a non-interchangeable trip unit and included line- and load-side lugs, the CAH3150 is configured for secure installation and consistent operation. It is well-suited for maintaining and servicing existing electrical systems that require a direct, form-fit-function replacement within the CAH series. Designed for durability and long-term service, the CAH3150 molded case circuit breaker supports safe, code-compliant electrical distribution while helping protect conductors, panels, and connected equipment from damage caused by overcurrent conditions.
