CAH2125 - 125Amp Circuit Breaker

CAH2125 - 125 Amp Circuit Breaker

The CAH2125 molded case circuit breaker is a 2-pole, 125 amp breaker designed for dependable overcurrent protection in 120/240VAC electrical distribution systems. Built on the CAH frame and rated for 40°C operation, this breaker features a non-interchangeable trip unit and includes both line- and load-side lugs for straightforward installation. With a 22kA A.I.C. interrupting rating at 120/240VAC, the CAH2125 is well-suited for protecting branch circuits and feeder applications in commercial and industrial panelboards. Its construction reflects the kind of durability you expect in legacy electrical systems—equipment that was built to last and designed to provide consistent circuit protection over time.

Whether you’re replacing an existing CAH frame breaker or maintaining an established power distribution system, the CAH2125 is engineered for proper form, fit, and function. It helps safeguard conductors and connected equipment from overloads and short circuits, helping reduce the risk of downtime and electrical damage in compatible systems.
