Description

The switches are designed to work as part of switchgear in networks of three-phase alternating current frequency of 50 Hz, rated voltage of 6 or 10 kV with isolated or grounded through arc-quenching reactor or resistor neutral. Overall and connection dimensions of switches allow to install them in complete switchgear (CSR, switchgear switchgear), when replacing circuit breakers that have served their time (retrofit), as well as for use as a means of switching in reclosers and other devices.
