CAH3150X - 150Amp Circuit Breaker

CAH3150X - 150 Amp Circuit Breaker

The CAH3150X molded case circuit breaker is a 150-amp, 3-pole breaker designed for reliable circuit protection in commercial and industrial electrical distribution systems operating at up to 240VAC. Built on the CAH frame platform, this breaker features a non-interchangeable trip unit calibrated for consistent overcurrent protection at 40°C. With a 22kA interrupting capacity at 240VAC, the CAH3150X is engineered to safely interrupt fault conditions while maintaining proper coordination within compatible panelboards and distribution equipment. Its molded case construction is built to last, helping protect conductors and connected equipment from overloads and short circuits in demanding environments. Load-side lugs are included, supporting secure conductor terminations and straightforward installation in systems designed for CAH frame breakers.

Whether you’re maintaining an existing facility or replacing a unit within a legacy distribution setup, the CAH3150X provides the form, fit, and function required for proper system operation—without modification to compatible equipment.
