AS Series

High Energy Metal-Oxide Arrester Blocks

The AS Series of Arrester blocks is primarily designed to be

used as the surge suppression element within a lightning

arrester assembly. These arrester blocks provide the high

peak surge current and energy ratings required for the

protection of high voltage AC power utility distribution

systems. Typically, these devices are placed within a special

arrester housing provided by the customer, and stacked to

achieve the necessary continuous working voltage ratings

for the specific application. (See the CA or NA series of

Varistor discs for lower voltage and energy applications.)
