3p D 4A 6kA VA47-63 PRO VA63-3P04D6 Era B0063223 miniature circuit breaker

Circuit breaker is an electromechanical switching device capable of making, carrying, and breaking currents under normal circuit conditions, as well as making, carrying for a specified time, and automatically breaking currents under specified abnormal circuit conditions, such as short-circuit currents. Circuit breakers can be single-, two-, three-, or four-pole and have the following structural components: main contact system, arc extinguishing system, trip mechanism drive, and trip elements. 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 (hoists, pumps) - switches with characteristic D.
