Over And Under Voltage Relay Protective Device V-protector Protector Vp-40a



Digital display self recovery over-voltage protector is mainly used for photovoltaic grid connected,household and similar low-voltage distribution lines. It can automatically disconnect when there is overvolatage,under voltage or voltage loss in the line,and can automatic detection of wire voltage.It is a protector that canautomatically closed when the line of electricity back to normal.


  1. The over voltage and under voltage protection threshold is adjustable,which is convenient for the user to set the voltage protection range in real time according to the power consumption environment.
  2. It can cut off the line in time when the over voltage occurs,and automatically connect the line after delay when the line is restored to normal without manual operation.
  3. Display range of effective voltage 70-400V
  4. With stand lightning surge voltage:5KV
