CAH2175W - 175Amp Circuit Breaker

CAH2175W - 175 Amp Circuit Breaker

The CAH2175W is a 2-pole, 175 amp molded case circuit breaker designed for dependable overcurrent protection in commercial and industrial electrical distribution systems operating at 120/240VAC. Built on the CAH frame, this breaker features a non-interchangeable trip unit calibrated for consistent thermal-magnetic protection at a standard 40°C ambient temperature. With a 22kA A.I.C. rating, the CAH2175W is engineered to interrupt fault currents within its specified rating, helping protect conductors and connected equipment from damage due to overloads and short circuits. This model is supplied without lugs installed, allowing compatibility with existing hardware configurations where applicable. Designed to meet the form, fit, and function requirements of legacy CAH-frame panelboards and switchgear, the CAH2175W provides a direct replacement solution for maintaining existing electrical systems.
