The CA3-B0-22-650-12A-D is a 3-pole hydraulic-magnetic circuit breaker designed for high-amperage and high-voltage applications in industrial, marine, and renewable energy systems. This breaker is rated for 50 A continuous current with a maximum voltage of 480 VAC (50/60 Hz) or 125 VDC, employing a series trip (current) mechanism for reliable overcurrent protection. The device features a unique arc chute design that enables interrupting capacities up to 10,000 amps, making it suitable for demanding electrical environments. It is available with a recessed off rocker actuator and 1/4-20 threaded stud terminals (6-32 x 0.195 inches mounting). Common applications include marine power distribution, datacom/telecom systems, generators, welders, and industrial automation equipment where compact yet robust protection is required.
