CAH3175 - 175Amp Circuit Breaker

CAH3175 - 175Amp Circuit Breaker

Keeping your electrical distribution system running smoothly often comes down to having the right replacement components when they're needed. The CAH3175 175 Amp 3-Pole Molded Case Circuit Breaker is designed for applications that require a 175-amp, 3-pole circuit breaker with a 22kA interrupting capacity at 240VAC. For maintenance teams, electricians, and facility managers working with existing equipment, matching the original breaker specifications is an important part of preserving system compatibility and minimizing unnecessary modifications.

Built with a non-interchangeable trip unit and supplied with line-side and load-side lugs, the CAH3175 is intended for use in compatible commercial and industrial electrical systems. Its compact CAH frame design helps it fit within existing equipment layouts, making it a practical choice for repair projects, planned maintenance, and equipment replacements. Designed to help protect your electrical circuits from overloads and short-circuit conditions, this molded case circuit breaker provides the ratings and configuration required for many established power distribution systems.

Electrical equipment is often expected to remain in service for decades, which is why properly matched replacement breakers continue to play such an important role in facility maintenance. The CAH3175 is built to last and offers a dependable form, fit, and functional replacement solution for compatible installations where maintaining the original system design is a priority.
