Switches are intended to replace the AVM series circuit breakers in operation and are manufactured based on the VA50-41 and VA50-43 series switches. The switches are used in AC electrical circuits with a rated voltage of up to 660 V at a frequency of 50 or 60 Hz for conducting current in normal mode and disconnecting during short circuits and overloads, as well as for infrequent (up to 10 times per day) operational switching of these circuits. The series is included in the list of domestic products according to RF Decree No. 719 (Ministry of Industry and Trade register).
