CAH2125Y - 125Amp Circuit Breaker

CAH2125Y - 125Amp Circuit Breaker

When you're maintaining existing electrical equipment, finding the right replacement breaker isn't about chasing the newest technology—it's about matching the original specifications and keeping the system operating as intended. The CAH2125Y is a 125 Amp, 2-pole molded case circuit breaker designed for applications that require a Type CAH breaker with a 22kA interrupting rating at 120/240VAC.

Whether you're replacing a failed breaker during a maintenance shutdown or sourcing parts for ongoing facility upkeep, having the correct amperage, pole configuration, and interrupting capacity can help simplify the process. Its compact molded case design and 40°C rating make it suitable for a wide range of installations that rely on Type CAH circuit protection.

Electrical systems in manufacturing plants, schools, office buildings, healthcare facilities, and municipal properties often remain in service for many years. That's why matching the original breaker specifications is critical. The CAH2125Y was built for exactly that purpose—providing the form, fit, and function required for compatible equipment while delivering dependable circuit protection where it's needed most.
