Vacuum circuit breakers MZW20-12A are three-phase high-voltage vacuum circuit breakers, for outdoor installation, designed for switching electrical circuits under normal and emergency conditions in three-phase alternating current networks with a frequency of 50 Hz with a rated voltage of up to 10 kV.
It is used for switching three-phase electrical circuits with a rated voltage of 12 / 13.8 / 15/24 kV, as well as for automatically disconnecting these circuits during short circuits and overloads.
It is also widely used as a safety and control device in traction substations, industrial and mining enterprises, in urban and rural distribution networks.
