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.
