25 kV relays

November 2005 Operator Interfaces, Switches & Relays

Gigavac's new G20 is a sealed single pole, single throw normally open (SPST-NO) 28 kV, 110 A vacuum relay. Its new G22 is almost identical to its G20, but rated 25 kV, 65 A and has tungsten contacts for hot switching lower current loads. This relay type is generally used in wafer fabrication equipment, aerospace radar and ECM, and airport lighting systems.

The G20 and G22 are both 96 mm tall and 38 mm wide. Both come with screw terminals for easy connections as well as through-panel mounting that keeps the high voltage and control circuits far apart - to eliminate cross talk and any chance of high voltage shorts to the coil circuit.

The new G20 and G22 coil voltages are 12; 26,5; 115 V d.c. or customised; and there is also Gigavac's changeable coil feature that allows users to change the coil even after the relay has been installed. Most popular models are in stock with special orders available within four weeks.
