CAH2125W - 125Amp Circuit Breaker

CAH2125W - 125Amp Circuit Breaker

If you're replacing an existing breaker, matching the original specifications is usually the first priority. The CAH2125W is a 125 Amp, 2-pole molded case circuit breaker commonly found in commercial and industrial electrical systems where the breaker type, ratings, and physical dimensions need to remain consistent with the equipment already in service.

This Type CAH breaker is rated 22kA at 120/240VAC and features a non-interchangeable trip unit. It is supplied without lugs installed, which can be helpful in applications where connection hardware is selected separately based on the equipment requirements. For maintenance personnel and electricians, details like interrupting capacity, pole count, and connection configuration are often what determine whether a breaker is the right fit for the job.

You'll find breakers like the CAH2125W in manufacturing facilities, warehouses, schools, office buildings, healthcare campuses, and municipal properties. In many of these environments, electrical systems remain in operation for years, making compatible replacement components an important part of routine maintenance. Built to last, the CAH2125W continues to be used in applications where maintaining the original system design is important.
