CA3125X - 125Amp Circuit Breaker Description
CA3125X - 125 Amp Circuit Breaker
The CA3125X circuit breaker is a 3-pole, 125-amp molded case circuit breaker designed to provide dependable overcurrent protection in 240VAC distribution systems. Built on the CA frame platform and rated for 10kA interrupting capacity at 240VAC, this breaker is engineered for consistent performance in commercial and industrial electrical panels requiring reliable branch or feeder circuit protection. Featuring a non-interchangeable trip unit calibrated for 40°C operation, the CA3125X delivers stable thermal-magnetic protection in environments where steady load management and short-circuit protection are critical. Load-side lugs are included, helping ensure proper conductor termination and secure installation. Designed for durability and long service life, this breaker is manufactured to meet the practical demands of legacy power distribution systems where exact form, fit, and function matter.
