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.)

STORAGE AND HANDLING NOTES:
1.Arrester blocks should be stored in a moisture free environment at all times.
2.Use caution during handling to prevent damage or chipping of edges of the arrester blocks.
CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
