CAH2125X - 125Amp Circuit Breaker

CAH2125X - 125Amp Circuit Breaker

Finding the right replacement circuit breaker isn't just about matching the amp rating—it's about making sure the breaker fits the application and performs as intended within the existing electrical system. The CAH2125X is a 125 Amp, 2-pole molded case circuit breaker designed for installations that require a Type CAH breaker with a 22kA interrupting capacity at 120/240VAC. Whether you're maintaining commercial equipment, servicing an industrial facility, or replacing a failed breaker in an existing distribution system, having the correct specifications can save valuable time and help keep projects moving forward.

Built with a non-interchangeable trip unit and supplied with load-side lugs, the CAH2125X is intended for applications where maintaining original equipment requirements is important. Its compact footprint and standard CAH configuration make it a practical solution for facilities that depend on proven electrical infrastructure. Designed for operation in environments up to 40°C (104°F), this breaker provides the form, fit, and function needed for compatible systems while supporting safe and dependable circuit protection. Built to last, it remains a trusted choice for maintenance teams, electrical contractors, and facility managers responsible for keeping electrical distribution systems operating properly.
