CAH2225X - 125Amp Circuit Breaker

CAH2225X - 125 Amp Circuit Breaker

The CAH2225X molded case circuit breaker is a 225 amp, 2-pole breaker designed for use in 120/240VAC distribution systems requiring dependable overcurrent protection. Built on the CAH frame platform, this breaker features a non-interchangeable trip unit calibrated for consistent thermal-magnetic performance at 40°C. With a 22kA interrupting rating at 120/240VAC, the CAH2225X is well-suited for commercial and industrial panelboards where proper fault interruption capacity is critical for safety and code compliance. This unit includes load-side lugs for secure conductor termination, helping streamline installation and ensuring proper fit within compatible assemblies. Like other molded case circuit breakers in its class, it is built to last and engineered for reliable, long-term service in demanding electrical environments.

Whether you’re maintaining an existing power distribution system or replacing a breaker within a CAH frame assembly, the CAH2225X provides the correct form, fit, and function required for legacy equipment compatibility.
