CAH3100Y - 100Amp Circuit Breaker

CAH3100Y - 100 Amp Circuit Breaker

The CAH3100Y circuit breaker is a 3 pole, 100 amp molded case circuit breaker designed for dependable circuit protection in commercial and industrial power distribution systems. Built on the CAH frame, this breaker delivers 22kA A.I.C. at 240VAC, making it suitable for applications where reliable interruption capacity is essential. Engineered for operation at 40°C, the CAH3100Y features a non-interchangeable trip unit and comes equipped with line-side lugs for secure conductor termination.

For facilities maintaining or servicing existing CAH-frame distribution equipment, this breaker provides the correct form, fit, and function replacement, helping ensure compatibility with established panelboards and switchgear assemblies. Molded case circuit breakers like the CAH3100Y are built to last, offering consistent thermal-magnetic protection against overloads and short circuits in three-phase systems.
