Modular circuit breaker 1P C 16A 4.5kA VA 47-29 SIMPLE-mod-03 ERA B0039220

Circuit breaker is a contact switching device capable of switching, conducting, and disconnecting currents under normal conditions in the circuit, as well as switching, conducting for a rated (set) time, and automatically disconnecting currents under 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 units: main contact system, arc suppression system, trip device drive, and trip units. VA47-29 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.
