What is the performance of Rollarc R400/R400D contactor at 0 bar relative?

Although it is not normal condition to have gas leakage with Rollarc contactor, however, the contactor still keeps at 0 bar of SF6 pressure the following performances:
  • The nominal performance.
  • The capacity to break once at least 2,2 kA at 7.2 kV.
  • The capacity to withstand at least 80 % of the insulating level.
This allows the user/operator in event of gas leakage to plan for the shut-down & further inspection operations thus minimizing the impact on service continuity that might be caused.
