The CA2-B0-46-640-11D-C is a C-Series hydraulic-magnetic circuit breaker designed for overcurrent protection in high amperage and voltage applications. This device is configured as a two-pole unit with a handle actuator and a series trip circuit. It is rated for 40A and operates at 50/60Hz with a long time delay characteristic and high-inrush tolerance, making it suitable for circuits with initial current surges. The breaker features 10-32 stud terminals for secure connections and is designed for mounting with ISO M3 x 5mm inserts, including barriers for applications with voltages of 300V or higher. As part of the robust C-Series, it is well-suited for demanding environments such as marine systems, renewable energy, military equipment, and industrial automation.
