CHH3175H2 - 175Amp Circuit Breaker

CHH3175H2 - 175 Amp Circuit Breaker

The CHH3175H2 molded case circuit breaker is designed to provide dependable circuit protection in electrical distribution systems that require a 175-amp, 3-pole breaker within the CHH2 frame platform. Built with a non-interchangeable trip unit, this breaker delivers consistent overcurrent protection for conductors and connected equipment while maintaining compatibility with existing CHH2-series installations. Its 25kA interrupting capacity at 240VAC allows it to safely interrupt fault conditions in commercial and industrial power systems. The CHH3175H2 is commonly selected when maintaining or servicing established electrical panels where the correct frame type, amperage rating, and pole configuration are critical for proper fit and function. Molded case circuit breakers like this one are built to last and continue to be widely used in facilities that rely on proven electrical protection components.
