CAH3150X - 150Amp Circuit Breaker

CAH3150X - 150Amp Circuit Breaker

When you're maintaining an existing electrical distribution system, finding the right replacement breaker is about more than matching the amperage. The CAH3150X 150 Amp 3-Pole Molded Case Circuit Breaker is designed for applications that require the specific ratings, dimensions, and configuration of a CAH-frame breaker. Whether you're replacing a failed unit during scheduled maintenance or sourcing a compatible breaker for an existing installation, having the correct fit can help reduce downtime and simplify the replacement process.

Rated at 150 amps with a 22kA interrupting capacity at 240VAC, the CAH3150X is built for use in commercial and industrial electrical systems where dependable circuit protection is essential. The breaker features a non-interchangeable trip unit and comes with load-side lugs included, making it suitable for installations that require these original specifications. Its compact footprint allows it to fit into compatible equipment without unnecessary modifications, helping electricians and maintenance teams keep projects moving efficiently. Like many molded case circuit breakers used in long-service electrical systems, the CAH3150X is built to last and designed to support the continued operation of compatible equipment.
