CAH3175X - 175Amp Circuit Breaker

CAH3175X - 175Amp Circuit Breaker

When a breaker needs to be replaced, finding the correct match can save a lot of time in the field. The CAH3175X 175 Amp 3-Pole Molded Case Circuit Breaker is built for systems that require a 175 amp, 3-pole breaker with a 22kA interrupting rating at 240VAC. For electricians and maintenance teams working with existing equipment, matching the original specifications is often the easiest way to keep a project moving and avoid unnecessary modifications.

This breaker features a non-interchangeable trip unit and comes with load-side lugs installed, making it a good fit for compatible CAH-frame applications. Whether you're replacing a breaker during scheduled maintenance or responding to an unexpected outage, having the right ratings and connection configuration helps simplify the job. Its compact size also makes it suitable for equipment designed around this breaker style.

In many facilities, electrical distribution equipment remains in service for years. That's why replacement components are often chosen based on compatibility as much as electrical ratings. Built to last and intended for form, fit, and functional replacement, the CAH3175X helps keep existing systems operating without changing the original design.
