AS Series Data Sheet January 1998 File Number 2492.4 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.) Features • Provided in Disc Form for Unique Packaging by Customer • Electrode Finish Enables Pressure Contact for Stacking Application • Available Disc Sizes: 32mm, 42mm and 60mm Diameter • No Follow Current • High Surge Current Capability • Conforms to IEC 99-4 and ANSI/IEEE C62.11 Industry Standards • Characterized for Lightning Arrester Parameters [ /Title (AS Series) /Subject (High Energy MetalOxide Arreste r Blocks ) /Autho r () /Keywords (TVS, Transient Suppression, Protection, Arreste r, Lightning Protection, Applications • Lightning Protection of Electrical AC Distribution Transformers and Systems • Arrester Assemblies of the Porcelain Polymeric, “Under-oil” and Metal Clad Variety d de n e – mm ns o g c i e s s tR Ha De s w No e d rie rN ue Se t o n t i F en nt uc m o d e c o c Pr Dis epla n e R Be No h t Wi Packaging AS SERIES OBSOLETE PART 8-3 1-800-999-9445 or 1-847-824-1188 | Copyright © Littelfuse, Inc. 1998 AS Series Absolute Maximum Ratings Rated Voltage AC Voltage Range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

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.
