CAH2225 - 225Amp Circuit Breaker

CAH2225 - 225 Amp Circuit Breaker

The CAH2225 molded case circuit breaker is a 2-pole, 225-amp solution designed to provide dependable overcurrent protection in 120/240VAC electrical distribution systems. Built on the CAH frame platform, this breaker features a non-interchangeable trip unit calibrated for consistent performance in environments rated up to 40°C. With a 22kA A.I.C. interrupting capacity at 120/240VAC, the CAH2225 is engineered to safely interrupt fault currents within its rating, helping protect conductors, panelboards, and connected equipment from damage due to overloads or short circuits. This molded case circuit breaker is designed for form, fit, and functional replacement in compatible legacy electrical systems utilizing the CAH frame type. It includes both line- and load-side lugs, simplifying installation and ensuring proper conductor termination. Built with durable internal components and a solid molded case housing, the CAH2225 is constructed to last under normal operating conditions when applied within its specified ratings. For maintenance professionals, facility managers, and electrical contractors seeking a direct replacement breaker with matching electrical characteristics, this unit delivers the necessary compatibility and protection required for continued system operation.
