Metal-Oxide Varistors (MOVs)
Industrial High Energy Terminal Varistors > HA Series
HA Varistor Series
RoHS
Description
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 MOVs 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."

Example - For an 8/20 µs Current Waveform:

Should transients occur in rapid succession, the average power
dissipation 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 above. 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.
