The CA1-B2-46-450-121-C is a C-Series single-pole hydraulic-magnetic circuit breaker designed for overcurrent protection. It features a series trip circuit with a current rating of 5.0A and operates at 50/60Hz. This model incorporates a long time delay with high-inrush tolerance, making it ideal for protecting circuits with significant start-up currents. The breaker is configured with a single-pole, double-throw (S.P.D.T.) auxiliary switch, 10-32 stud terminals, and a handle actuator. Its robust design is suitable for applications such as marine systems, renewable energy, and industrial automation.
