CA2125W - 125Amp Circuit Breaker

CA2125W - 125 Amp Circuit Breaker

The CA2125W molded case circuit breaker is a 2-pole, 125 amp breaker designed for dependable circuit protection in 120/240VAC electrical distribution systems. Built on the CA frame platform and rated for 10kA A.I.C. at 120/240VAC, this breaker provides essential overcurrent protection for branch and feeder circuits in commercial and industrial applications. Engineered for use in 40°C environments, the CA2125W features a non-interchangeable trip unit, helping maintain consistent trip characteristics aligned with original equipment specifications. If you’re maintaining or servicing an existing CA frame panel or distribution system, this breaker is designed for proper form, fit, and function compatibility within its intended configuration. Constructed as a molded case circuit breaker (MCCB), the CA2125W is built to last and intended for long-term service in legacy systems where matching frame type, amperage, and interrupting capacity is critical. Please note that no lugs are installed, allowing flexibility for applications requiring specific lug configurations.
