CAH2225Y - 225Amp Circuit Breaker

CAH2225Y - 225 Amp Circuit Breaker

The CAH2225Y molded case circuit breaker is a 225 amp, 2-pole breaker designed to provide dependable overcurrent protection in 120/240VAC electrical distribution systems. Built on the CAH frame platform, this unit features a non-interchangeable trip unit calibrated for consistent thermal-magnetic protection at 40°C. With a 22kA A.I.C. rating at 120/240VAC, the CAH2225Y is well-suited for commercial and industrial panelboards, switchboards, and distribution equipment where reliable interruption capacity is essential. It includes factory-installed line-side lugs for secure conductor termination, helping streamline installation and ensuring proper fit within compatible legacy systems. Constructed as a molded case circuit breaker, it is built to last and engineered to meet the practical demands of everyday electrical protection.

Whether you’re maintaining existing infrastructure or replacing a breaker with matching frame and ratings, the CAH2225Y provides the correct form, fit, and function required for compatible CAH frame applications.
