  • Additional arm coupling to provide larger gap between arms.
  • A built-in differential pressure switch operates the timer when the electrode force is correct.
  • All transformers are coated with F class insulation material.
  • Test are made using 4000 volts.
  • To be used with arms item 7401/7402/7403/7404/7405/7406/7407.
