High Energy Industrial

BA/BB Varistor Series

The BA and BB Series transient surge suppressors are heavy-duty

industrial metal-oxide varistors (MOVs) 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 models are rated from 130 to

880VM(AC) . The BB models from 1100 to 2800VM(AC) .

Both the BA and BB Series feature improved creep and strike capability

to minimize breakdown along the package surface, a package design

that provides complete electrical isolation of the disc subassembly, and

rigid terminals to insure secure wire contacts.

See BA/BB Series Device Ratings and Specifications table for part

number and brand information.
