CA3225X - 225Amp Circuit Breaker

CA3225X - 225 Amp Circuit Breaker

The CA3225X circuit breaker is a 225 amp, 3 pole molded case circuit breaker designed for dependable overcurrent protection in commercial and industrial power distribution systems. Built on the CA frame platform, this breaker features a non-interchangeable trip unit calibrated for operation at 40°C, making it suitable for standard ambient electrical room conditions. With a 10k A.I.C. rating at 240VAC, the CA3225X provides the interrupting capacity required to help protect conductors and equipment from damage caused by overloads and short circuits. It includes load-side lugs for secure conductor termination and is engineered for proper form, fit, and function in compatible panelboards and distribution equipment originally designed for CA frame devices. These breakers were built to last and continue to serve as reliable solutions for maintaining existing electrical systems.
