EA Series Latching 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. 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. |
