CA2125 - 125Amp Circuit Breaker

CA2125 - 125 Amp Circuit Breaker

The CA2125 molded case circuit breaker is a 2-pole, 125-amp thermal-magnetic breaker designed for dependable overcurrent protection in 120/240VAC electrical distribution systems. Built on the CA frame platform, this breaker features a non-interchangeable trip unit calibrated for 40°C operation, making it well-suited for standard commercial and industrial environments. With a 10kA A.I.C. rating at 120/240VAC, the CA2125 provides the interrupting capacity required for many branch and feeder circuit applications. Line and load-side lugs are included, supporting straightforward installation and secure conductor termination. Designed for proper form, fit, and function in compatible legacy panelboards and distribution equipment, this unit helps maintain system integrity while meeting applicable electrical standards.
