CAH3225X - 225Amp Circuit Breaker

CAH3225X - 225 Amp Circuit Breaker

The CAH3225X molded case circuit breaker is a 225-amp, 3-pole breaker designed to provide dependable overcurrent protection in commercial and industrial electrical distribution systems. Built on a CAH frame and rated for 22kA interrupting capacity at 240VAC, this breaker is well-suited for maintaining and servicing existing panelboards and switchgear that require a properly matched, form-fit-function replacement. Engineered for operation at 40°C, the CAH3225X features a non-interchangeable trip unit and includes load-side lugs for secure conductor termination. Its solid construction and precise ratings make it a practical solution for electricians, facility managers, and maintenance teams who need a breaker built to last and aligned with established system specifications. By matching amperage, frame type, and interrupting capacity requirements, the CAH3225X helps maintain system integrity while supporting safe and code-compliant electrical protection.
