Circuit breaker 1p C 16A 4.5kA VA47-63 PRO ERA B0059407

Circuit breaker - a contact switching device capable of switching, conducting, and disconnecting currents under normal conditions in the circuit, as well as switching, conducting, and automatically disconnecting currents during rated abnormal conditions in the circuit, such as short-circuit currents. Circuit breakers can be single-pole, two-pole, three-pole, or four-pole and have the following structural components: main contact system, arc suppression system, trip unit drive, and trip units. VA47-63 circuit breakers are designed to protect distribution and group circuits with various loads: electrical appliances, lighting - switches with characteristic B; motors with small inrush currents (compressor, fan) - switches with characteristic C; motors with large inrush currents (lifting mechanisms, pumps) - switches with characteristic D.
