CA3125Y - 125Amp Circuit Breaker

CA3125Y - 125 Amp Circuit Breaker

The CA3125Y circuit breaker is a 3-pole, 125 amp molded case circuit breaker designed to provide dependable overcurrent protection in commercial and industrial electrical distribution systems. Built on a CA frame with a non-interchangeable trip unit, this breaker is rated for 10kA A.I.C. at 240VAC and calibrated for operation at 40°C, making it suitable for standard operating environments. It includes line-side lugs for secure conductor termination and straightforward installation. Designed for proper form, fit, and function within compatible panelboards and switchboards, the CA3125Y is engineered to deliver consistent circuit protection in systems that require this specific configuration and rating.

This breaker is built to last and intended for use where maintaining the original equipment specifications is critical. Whether replacing an existing CA frame breaker or maintaining legacy electrical infrastructure, the CA3125Y provides the ratings and configuration required for reliable branch or feeder circuit protection.
