CAH2150X - 150Amp Circuit Breaker

CAH2150X - 150 Amp Circuit Breaker

The CAH2150X circuit breaker is a 2-pole, 150 amp molded case circuit breaker designed for reliable overcurrent protection in 120/240VAC electrical distribution systems. Built on the CAH frame with a non-interchangeable trip unit, this breaker provides consistent thermal-magnetic protection in commercial and industrial panelboards and load centers requiring a 22kA interrupting capacity. Engineered for operation at 40°C, the CAH2150X is well suited for demanding environments where dependable circuit protection and proper fit within existing equipment are critical. Load-side lugs are included, supporting straightforward installation and secure conductor termination. As part of a long-standing molded case breaker platform, this unit is built to last and intended to provide safe, code-aligned protection in compatible legacy systems.
