Description
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 880V
to 2800V
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
ensure secure wire contacts.
See BA/BB Series Device Ratings and Specifications Table
for part number and brand information.
