CAH3175W - 175Amp Circuit Breaker

CAH3175W - 175Amp Circuit Breaker

When you're maintaining an existing electrical distribution system, finding the right replacement breaker isn't just about matching the amperage. The CAH3175W is a 175 amp, 3-pole molded case circuit breaker designed for applications where proper fit, electrical ratings, and compatibility with existing equipment are essential. Featuring a 22kA interrupting rating at 240VAC and a non-interchangeable trip unit, this breaker helps maintain the original design characteristics of compatible systems without unnecessary modifications.

Built for use in commercial and industrial environments, the CAH3175W provides dependable circuit protection against overloads and short circuits while fitting into installations that require a CAH-frame breaker. Its compact design makes it suitable for a variety of switchgear, panel, and distribution applications where space and equipment compatibility matter. With no lugs installed, connection hardware can be selected according to the specific requirements of the installation. Like many molded case breakers used in long-serving electrical systems, the CAH3175W was built with durability in mind and remains a practical solution for maintaining existing infrastructure.
