CA3150X - 150Amp Circuit Breaker

CA3150X - 150 Amp Circuit Breaker

The CA3150X is a 3-pole, 150 amp molded case circuit breaker built on the CA frame platform and rated 10kA at 240VAC. It’s designed for dependable overcurrent protection in three-phase electrical systems commonly found in commercial and industrial facilities. With a factory-set, non-interchangeable trip unit calibrated at 40°C, this breaker delivers consistent protection that aligns with its original design specifications. Load-side lugs are included, making conductor termination straightforward in compatible installations. If you’re maintaining or servicing equipment that requires a CA frame breaker with these exact ratings, the CA3150X provides the proper form, fit, and function needed to keep the system operating as intended.
