CHH3175H2 - 175Amp Circuit Breaker

CHH3175H2 - 175Amp Circuit Breaker

When your CHH2 breaker needs to be replaced, it’s usually not about changing anything—it’s about matching what’s already installed so the system stays consistent. The CHH3175H2 is a 175 Amp, 3-pole molded case circuit breaker used in existing CHH2 electrical systems where a direct replacement is required to keep the original setup intact.

This breaker is rated for 240VAC three-phase applications, where all three poles work together to disconnect power. It’s commonly used in feeder circuits, distribution panels, and other parts of commercial and industrial systems that are already built around CHH2 equipment. In most cases, the panel is staying in service, so the replacement needs to fit without changes to layout or wiring.

Most of the time, this breaker is installed during maintenance or repair work. If your existing unit is already a CHH2-series 175 Amp, 3-pole breaker, the CHH3175 typically drops into the same space and maintains the original configuration.

Like other molded case breakers used in established electrical systems, it’s intended for service in properly maintained equipment and is built to last in everyday industrial and commercial use.
