CAH3175Y - 175Amp Circuit Breaker

CAH3175Y - 175Amp Circuit Breaker

If you're replacing a breaker in an existing electrical distribution system, matching the original specifications is often the first thing on the checklist. The CAH3175Y 175 Amp 3-Pole Molded Case Circuit Breaker is built for applications that require a 175 amp rating, three poles, and a 22kA interrupting capacity at 240VAC. With its non-interchangeable trip unit and line-side lugs included, it offers the configuration needed for many compatible CAH-frame installations.

Whether the job involves routine maintenance, a repair project, or replacing a failed breaker, having the correct fit can make all the difference. The CAH3175Y is designed for equipment built around this breaker style, helping maintenance teams and electricians avoid unnecessary modifications when working with existing systems. Its compact size and established CAH frame design make it a practical choice for facilities that continue to rely on proven electrical infrastructure.

In many commercial and industrial buildings, electrical equipment remains in service for years. When replacement components are needed, compatibility is just as important as the electrical rating itself. Built to last and intended for form, fit, and functional replacement, the CAH3175Y helps support the continued operation of compatible equipment while preserving the original system configuration.
