CHH3175 - 175Amp Circuit Breaker

CHH3175 - 175Amp Circuit Breaker

When you’re replacing a breaker in an existing CHH system, it usually comes down to one thing—matching what’s already in the panel so everything stays consistent. The CHH3175 is a 175 Amp, 3-pole molded case circuit breaker used in CHH-series installations where the original setup is still in place and the goal is a straightforward replacement.

The non-interchangeable trip unit is factory set, meaning there are no field-adjustable parts inside the breaker. That keeps things simple during replacement—especially when the existing equipment is already standardized around CHH components.

Most of the time, this breaker shows up during maintenance work. If the original unit is a CHH-series 175 Amp, 3-pole breaker, the CHH3175 typically drops into the same space and keeps the panel layout unchanged.

Like many molded case breakers used in long-running electrical systems, it’s intended for use in properly maintained equipment and is built to last in service over time.
