Can Rollarc R400/400D contactor break short circuit currents?

Rollarc SF6 contactor has been tested for short circuit breaking currents as below: 
  • 10kA at 7.2kV 
  • 8kA at 12kV 
Thus the contactor can break short circuit current values up to this limit; in case it was necessary to obtain a higher value of breaking current, it is common to either combine the Rollarc contactor with upstream fuses with adequate breaking capacity or to use a circuit breaker properly sized according to the application.
