Switch operation performance
for today ... tomorrow ... the 2000's

Current-carrying parts
The AR Switch blades are formed from hard-drawn, high-conductivity copper for maximum current carrying capability. The leading edge of the Blade incorporates a copper-tungsten inlay, for fault closing performance. The stationary contacts are high-conductivity copper with phosphorous-bronze back-up springs to maintain optimum contact pressure and operating ease. The stationary contact also includes a copper-tungsten fault close tip. All current transfer points are silver to silver.

The hinged contact includes a stainless steel compression spring for optimum contact pressure, operating ease and terminal pad stability. All current transfer points are silver to silver.

Opening Sequence: Switch Blade and Interrupter
1 Switch blade in closed position	2 As switch blade is opened, current is trans-ferred to the Interrupter before the main con-tacts fully separate
3 Current is fully transferred to the Interrupter and arc interruption is accomplished by thermal interaction of the arc on the specifically designed arc trailer and liner within the interrupter	4 Switch is fully opened and the Interrupter self-resets
