IEC Withdrawable Vacuum Contactor-Fuse Combination Truck
Product safety features
The contactor is prevented from closing and a panel indication is provided when:
- Fuse blown and or Fuse not fitted
- Additional interlock options are available to interface with the panel if appropriate panel designs are incorporated such that:
- The truck is prevented from being racked in if:
- The front door is open
- The earth switch is ON - The earth switch cannot be switched ON if the truck is in the Service Position
- The panel door cannot be opened if the truck is in the Service Position
