The PA Series of transient surge suppressors are metal-oxide varistors (MOVs) featuring a rigid base mount package construction, and are useful in applications which are subject to vibration.
  • The UL and CSA recognized varistors are available in a wide range of operating voltages, from 130V to 660 V V M(AC)RMS .
  • The base-mount package has a quick-connect tab terminal that provides a fast, secure lead attach.
  • The mounting base forms the second electrical connection, usually chassis ground.
Meeting rigid NEMA standards, PA series varistors have a creep and strike distance capability that minimizes breakdown along the package surface.

pdficon 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.
pdficon 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.
pdficon 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.
