CAH2175Y - 175Amp Circuit Breaker

CAH2175Y - 175 Amp Circuit Breaker

The CAH2175Y molded case circuit breaker is a 2-pole, 175 amp unit designed for dependable overcurrent protection in 120/240VAC electrical distribution systems. Built on the CAH frame with a non-interchangeable trip unit, this breaker is engineered for consistent thermal-magnetic protection in commercial and industrial panelboards and switchboards operating at 40°C. With a 22kA A.I.C. interrupting rating at 120/240VAC, the CAH2175Y is well-suited for applications requiring reliable fault interruption capacity in legacy and existing power distribution systems. Line-side lugs are included, supporting secure conductor terminations and streamlined installation. Constructed as a durable molded case circuit breaker built to last, this unit provides the form, fit, and function required for direct replacement within compatible CAH frame assemblies.
