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”.

Features:
  • RoHS compliant and Lead–free 
  • Wide operating voltage range
     VM(AC)RMS
     110V to 750V
  • Two disc sizes available 32mm and 40mm
  • High energy absorption capability WTM = 170J to 1050J
  • High peak pulse current capability, ITM = 25,000A to 40,000A
  • Rigid terminals for secure mounting
  • Available in trimmed version for through hole board mounting Designation "HC"
  • No derating up to 85ºC ambient

HA Series transient surge suppressors are industrial high energy Metal-Oxide Varistors (MOVs)...

AN9768 Transient Suppression Devices and Principles

This application note discusses the two major categories of transient suppressors: a) those that attenuate transients, thus preventing their propagation into the sensitive circuit; and b) those that divert transients away from sensitive loads and so limit the residual voltages.

AN9769 An Overview of Electromagnetic and Lightning Induced Voltage Transients

This application note is an overview of the sources and nature of various transient overvoltages, and the problems that may result.

EC608 Considerations for Selecting Littelfuse MOVs and Fuses for Industrial Motor Applications

This application note discusses the first level considerations for applying both Littelfuse Industrial AC Line Metal Oxide Varistors and associated AC line Fuses with a motor protection example.

pdf icon Combining GDTs and MOVs for Surge Protection of AC Power Lines Application Note

This application note illustrates how to design high performance, cost-effective surge protection for equipment connected to AC power lines. The role of gas discharge tube (GDT) surge arresters specifically designed for AC power line protection is also be discussed.
