HA Series transient surge suppressors are industrial hgh energy metal-oxide varistors (MOVs). They are designed to provide secondary surge protection in the outdoor and servie 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”.
