Westinghouse Voltrap Voltage Suppressor

Hello,
need help with datasheet for Westinghouse Voltrap Voltage Suppressor S02AA36AC.
Looks like this: http://www.maraindustrial.com/cart/electrical/westinghouse-s04de09cc-voltrapvoltage-suppressor.html
Can't find datasheet, or replacement, or where to buy.
Thank you.

 

These Selenium Suppressors were made by Westinghouse and the Data sheet archive may be found at www.datasheetarchive.com\selenium. Note that the entire line of suppressors was acquired by CKE Rectifier Corp. which may or may not still be in business. The company was storing the selenium scrap pieces in large drums as it was considered a hazardous substance and could not be disposed of in a landfill. These suppressors were useful in supression of DC arcing and were available in many sizes and energy ratings.
