Powell-ESCO Company Phase Vacuum Fault Interrupter Switches combine the cost and operational benefits of fuseless, electronically controlled, re-settable overcurrent protection, and resettable inrush restraint with the safety and maintenance benefits of a totally sealed, dead front, SF6 insulated device. The switches are designed for 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. They are ideal for the replacement of existing oil fuse cutouts or conventional fuse protection in vault locations or wherever economical overcurrent protection is required. Other features include:
•Protection curve capability
•Inrush restraint
•Auxiliary power plug
•Time delay close
•Control power transformer switch
•Dual voltage operation
