Lucy Electric Air Break Switch Disconnector

The Lucy Electric Rapier SAX Air Break Switch Disconnector range is compact and robust, providing a reliable, lightweight and flexible solution for network isolation and reinstatement. The Rapier AX Solid Blade air break switch disconnector is an evolution of the existing Rapier RX and AX air break switch disconnector. The tin plated multiple copper laminate strips have been replaced with 2 plated copper bars which form the main current path and also the moving female contact, this complete air break switch disconnector normally comprises of 3 single phase units ganged together with a common operating mechanism ensuring that all phases open and close at the same time.

The mounting base is common across all three voltage ranges – 12/15.5, 24 and 36 kV making design of mounting steelwork simpler.
