These Vacuum Interrupter Switches are designed to combine the total cost and operational benefits of fuseless, electronically controlled, re-settable overcurrent protection, and re-settable inrush restraint with the safety and maintenance benefits of a totally sealed, dead front, SF6 insulated device. They provide automatic three phase fault interruption with manual loadbreak and sectionalizing capabilities for distribution systems rated from 15kV to 27kV with up to 600A continuous current and 12kA symmetric fault interrupting.
The switches are well suited for the replacement of existing oil fuse cutouts or conventional fuse protection in vault locations or wherever economical overcurrent protection is required. Additional features include:
Non-flammable SF6 gas insulating media
Vacuum bottle interrupter technology
Re-settable, fuseless protection
Selectable trip levels
Numerous protection curves
Remote or SCADA operation
Loadbreak switching capability
Time-delayed closing operation
Auxiliary Power Plug
Control Power Transformer Switch
Dual Voltage Operation
