CAH3175Y - 175Amp Circuit Breaker

CAH3175Y - 175 Amp Circuit Breaker

The CAH3175Y circuit breaker is a 3-pole, 175-amp molded case circuit breaker designed for reliable overcurrent protection in commercial and industrial electrical distribution systems. Built on the CAH frame and rated for 22kA interrupting capacity at 240VAC, this breaker is engineered to provide dependable protection against overloads and short circuits in 40°C ambient conditions. It features a non-interchangeable trip unit and includes line-side lugs, making it well-suited for direct replacement in compatible legacy panels and switchgear. Designed for long-term service, the CAH3175Y delivers the form, fit, and function required to maintain system integrity without modification to existing equipment layouts.

With a solid molded case construction and a ship weight of approximately 4.13 lbs., this breaker is built to handle demanding electrical environments while maintaining consistent performance under rated conditions. Whether you’re maintaining existing infrastructure or restoring power distribution equipment to proper working order, the CAH3175Y provides the ratings and compatibility required for safe, code-aligned installations.
