The CA1-B0-34-650-321-C is a C-Series hydraulic-magnetic circuit breaker designed for high amperage and voltage applications with a compact form factor. This single-pole breaker is rated for 50 amperes at 480 VAC (50/60 Hz) or 125 VDC maximum, employing a series trip (current) mechanism for reliable overcurrent protection. The breaker features a unique arc chute design that enables high interrupting capacities of up to 10,000 amps, making it suitable for demanding industrial and marine environments. It is available with a recessed off rocker actuator and 1/4-20 threaded stud terminals. Common applications include marine systems, renewable energy installations, generators, welders, industrial automation, and commercial food equipment where robust circuit protection is essential.
