The BA and BB Series transient surge suppressors are heavy-duty industrial metal-oxide varistors (MOV) designed to provide surge protection for motor controls and power supplies used in oil-drilling, mining, transportation equipment and other heavy industrial AC line applications.
  • These UL-recognized varistors have similar package construction but differ in size and ratings.
  • The BA modelsa are rated from 130 to 880V M(AC) .
Both the BA and BB Series feature improved creep and strike capability to minimize breakdown along the package surface. This package design provides both complete electrical isolation of the disk subassembly, and rigid terminals to insure secure wire contacts. Remove 'a package surface' second occurance.
See BA/BB Series Device Ratings and Specifications table for part number and brand information.

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.

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.
