CAH3125 - 125Amp Circuit Breaker

CAH3125 - 125Amp Circuit Breaker

When it's time to replace a breaker, getting the right match is usually the priority. The CAH3125 125 Amp 3-Pole Molded Case Circuit Breaker is commonly used in existing commercial and industrial electrical systems where the original equipment specifications need to stay the same. For maintenance teams, electricians, and facility managers, finding a breaker with the correct ratings and configuration can help you avoid unnecessary changes and keep a project moving forward.

The CAH3125 features a 125-amp rating, a 3-pole design, and a 22kA interrupting capacity at 240VAC. It comes with both line-side and load-side lugs installed and uses a non-interchangeable trip unit.

Electrical equipment is often expected to stay in service for many years, and replacement parts need to work within the system that's already in place. That's why many maintenance projects focus on compatibility first. Built to last and intended for form, fit, and functional replacement, the CAH3125 helps support your existing power distribution equipment without requiring modifications to the original setup.
