High Voltage Switches




Earth Switch ES-230 and ES-24 Series





REMO-HSE 120kV Earth Switch
120 kV or 150 kV High Voltage Earth Switch
Especially designed for electrostatic applications.



Technical Data



  • High voltage earth switch in a sealed brass case filled with insulation oil
  • Compact design
  • High voltage will be disconnected from ground as soon as the control voltage is connected
    After switching off the control voltage the high voltage is connected to ground via e.g. 430 MOhm first and then shorted with delay.
    Advantage: lower endangering of adjoining electronic systems.
  • Dry plug-in connector, greasing not necessary
  • Vertical mode of operation; switch closes under gravity.
