SUBJECT: Technical Specifications for 5 kA, Normal-Duty
Distribution 4.5 kV and 5 kV VariSTAR® MOV Disks
Technical Data
TD-231
APPLICATION
The VariSTAR MOV (Metal Oxide Varistor) disks described in this Technical Data sheet are for
use as active elements in IEC 5 kA and ANSI Normal-Duty Distribution Class Surge Arresters,
when applied in an appropriately designed arrester.
Polymer Housed Arrester Designs:
Use the glass collared AV5NG series VariSTAR disks, when applying disks to a polymer housed
arrester, where the dielectric strength of the material in direct contact with the disks exceeds the
dielectric strength of air.
Porcelain Housed Arrester Designs:
Option 1.
Use the glass collared AV5NG series VariSTAR disk together with an Epoxy Film Tape, as
described in technical data sheet TD-241, when applying disks in a porcelain housed arrester,
where the material in direct contact with the VariSTAR disks is equal to the dielectric strength of air.
Option 2.
Use the epoxy collared AV5NE series VariSTAR disks, when applying disks in a porcelain
housed arrester, where the dielectric strength of the material in direct contact with the disks is
equal to the dielectric strength of air.
Electrical properties for AV5NG and AV5NE series VariSTAR disks are otherwise identical.

Note: For individual disk reference
only. Not for ordering.
STORAGE AND HANDLING
The VariSTAR MOV disks are packaged on wooden pallets and
secured for ocean container shipment. The pallet/boxes shall be
stored indoors until the purchaser’s acceptance test. Once
opened, the disks shall be stored in a dry and clean environment to
avoid moisture or other contaminants to collect on the disk surface.
The MOV disk should not be handled with bare hands. A latex or
other non-fibrous glove should be used to prevent contaminants
from compromising the collar of the disk.
