Three Phase Vacuum Fault Interrupter [2010-10-09]

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
•Inrush Restraint
•Auxiliary Power Plug
•Control Power Transformer Switch
•Dual Voltage Operation
