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
terminals for screw 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.

Power Dissipation Ratings
Should transients occur in rapid succession, the average power dissipa-
tion required is simply the energy (watt-seconds) per pulse times the
number of pulses per second. The power so developed must be within
the specifications shown on the Device Ratings and Specifications table
for the specific device. Furthermore, the operating values need to be
derated at high temperatures as shown in Figure 1. Because varistors
can only dissipate a relatively small amount of average power they are,
therefore, not suitable for repetitive applications that involve substantial
amounts for average power dissipation.
