CA2125X - 125Amp Circuit Breaker

CA2125X - 125 Amp Circuit Breaker

The CA2125X molded case circuit breaker is a 2-pole, 125 amp breaker designed for dependable overcurrent protection in 120/240VAC electrical distribution systems. Built on a CA frame with a non-interchangeable trip unit, this breaker provides consistent thermal-magnetic protection for branch and feeder circuits in commercial and industrial panels. Rated at 10k A.I.C. at 120/240VAC, the CA2125X is engineered to interrupt fault currents safely while maintaining proper coordination within existing electrical systems. Designed for operation in environments up to 40°C, it includes load-side lugs for secure conductor termination, helping streamline installation and replacement in compatible panelboards and distribution equipment. Constructed as a molded case circuit breaker, the CA2125X is built to last and intended to provide reliable circuit protection where proper ratings and specifications are required.
