CA3-B0-22-620-221-R is a hydraulic-magnetic circuit breaker from Carling Technologies' C-Series, designed for applications requiring higher amperage and voltage handling capability in a compact package. Based on the part number coding, this unit features a 20 amp current rating and utilizes stud 10-32 terminals. The C-Series employs a unique arc chute design allowing for interrupting capacities up to 10,000 amps, with thermoset glass-filled polyester half shell construction for increased mechanical and electrical strength. The wiping contacts mechanical linkage with two-step actuation provides high contact pressure and longer contact life. This circuit breaker is suitable for industrial and commercial applications where reliable overcurrent protection is required.
