CAH2125Y - 125Amp Circuit Breaker

CAH2125Y - 125 Amp Circuit Breaker

The CAH2125Y molded case circuit breaker is a 2-pole, 125 amp unit designed to provide dependable overcurrent protection in 120/240VAC electrical distribution systems. Built on the CAH frame platform, this breaker features a non-interchangeable trip unit calibrated for consistent thermal-magnetic protection at 40°C. With a 22kA A.I.C. rating, it is well-suited for commercial and industrial applications where reliable short-circuit interruption is required. The CAH2125Y includes line-side lugs for secure conductor terminations and is engineered for proper form, fit, and function within compatible panelboards and switchgear assemblies. Designed for long service life in demanding environments, this breaker supports safe system operation and code-compliant installations.

Whether you’re maintaining existing electrical infrastructure or replacing a compatible unit in a legacy distribution system, the CAH2125Y delivers the ratings and configuration required to match original equipment specifications without unnecessary modification.
