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.

Power Dissipation Ratings
Should transients occur in rapid succession, the average power dissipation
required is simply the energy (watt-seconds) per pulse times the number
of pulses per second. The power so developed must be within the
specifications shown on the Device Ratings and Characteristics table for
the specific device. Furthermore, the operating values need to be derated
at high temperatures as shown in Figure 1. Because varistors can only
dissipate a relatively small amount of average power they are, therefore,
not suitable for repetitive applications that involve substantial amounts of
average power dissipation.

NOTE: If pulse ratings are exceeded, a shift of V N(DC) (at specified current) of more than 10% could result.This type of shift, which normally results in a decrease of VN(DC),
may result in the device not meeting the original published specifications, but it does not prevent the device from continuing to function, and to provide ample protection.
