EA Series 12KV-40KV
The EA series of air insulated HV Relays is provided for higher
continuous and momentary currents, yet is still within a compact
size for 12KV to 40KV PK test in air. It has higher opening
and closing forces which minimize contact resistance and closing
bounce. Where no HV current interrupting rating is required,
it is widely used 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.
When supplied with the
optional 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. As on most
Ross HV Relays, one, two, or more sets of SPDT 15A, 250V AC and
1/2A, 125V DC auxiliary contacts are optionally available, if
required. Other auxiliary contact ratings are available. |
