The switches are designed to switch on and off under load sections of the electrical circuit of alternating three-phase current 400 and 630 A frequency of 50-60 Hz, rated voltage up to 10 kV, as well as to ensure safe work on the disconnected section with the help of stationary earthing switches. VNA is used in complete transformer substations (KTP), cabinets of complete switchgear (KRU), as well as single-sided service chambers (CSR).
