1 / 6 page November 2003 Supersedes 11/02 Page 1 of 6 File Ref: 235 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.
