Metal-Oxide Varistors (MOVs) Industrial High Energy Terminal Varistors > HA Series RoHS 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 designationHC Agency Approvals See Ratings and Specifications Table for part number and brand information.
