CA3150Y - 150Amp Circuit Breaker

CA3150Y - 150 Amp Circuit Breaker

The CA3150Y molded case circuit breaker is a 150 amp, 3-pole breaker built for three-phase electrical distribution systems operating at 240VAC. Designed on a CA frame with a fixed, non-interchangeable trip unit, this breaker provides dependable overcurrent protection for feeders and branch circuits in commercial and industrial settings. With an interrupting capacity of 10kA at 240VAC, it is rated to handle fault conditions within its specified limits while maintaining proper circuit protection. Calibrated for 40°C ambient conditions, the CA3150Y is intended for standard operating environments commonly found in electrical rooms and industrial facilities. It includes line-side lugs for straightforward termination and is designed for proper form, fit, and functional replacement in equipment that requires a CA frame breaker. For applications where maintaining compatibility with existing infrastructure is critical, this unit supports continued operation without modification to the original system design. Like many molded case breakers of its class, it is built to last in demanding electrical applications.
