High Energy Industrial
HA Varistor Series
HA Series transient surge suppressors are industrial high energy
metal-oxide varistors (MOVs). They are designed to provide secondary
surge protection in the outdoor and service entrance environment
(distribution panels) of buildings, and also in industrial applications for
motor controls and power supplies used in the oil-drilling, mining, and
transportation fields.
The design of the HA Series of metal oxide varistors provide rigid
www.DatetarmShineaelst4fUor.csocmrew mounting. Also available in a clipped lead version
for through hole board placement or to accommodate soldered leads -
designation “HC”.
See Ratings and Specifications table for part number and brand information.
