HIGH VOLTAGE RELAYS – EA Series Latching 12kV-40kV

Details

The EA series of air insulated HV relays is provided for higher continuous and momentary currents, yet is still within a compact size. It has higher opening and closing forces which minimize contact resistance and closing bounce. It is widely used (where no HV current interrupting rating is required) for high power load and tap selection, circuit isolation, and grounding or shorting. It has standard, weld resistant, silver plated, easily renewable copper alloy contacts. Also optionally available with special heavy duty arcing contacts of Tungsten alloy, this series is excellent for closing in on high capacitor discharge and momentary fault currents with long life capability in these applications. As on most Ross HV relays, two or more sets of SPDT auxiliary contacts are optionally available, if required.
