HA Varistor Series

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."

See Ratings and Speciﬁcations Table for part number and

brand information.
