The DA and DB Series transient surge suppressors are heavy-duty industrial metal-oxide varistors designed to provide surge protection for motor controls and power supplies used in oil-drilling, mining, and transportation equipment.
  • These UL-recognized varistors have identical ratings and specifications but differ in case construction to provide flexibility in equipment designs.
  • DA series devices feature rigid terminals to insure secure wire contacts.
  • Both the DA and DB series feature improved creep and strike distance capability to minimize breakdown along the package surface design that provides complete electrical isolation of the disc subassembly.

Features:
  • High energy absorption capability
    WTM up to 1050J
  • Wide operating voltage range
    VM(AC)RMS 130V to 750V
  • Screw terminals (DA Series),quick connect push-on connectors (DB Series)
  • Case design provides complete electrical isolation of disc subassembly
  • 40mm diameter disc
  • No derating up to 85ºC ambient
  • RoHS compliant

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.
