Item Description
Ross Engineering Corp. HAF71NC100ACUW high-voltage vacuum relay contactor, rated 70 KV, built around a Westinghouse vacuum interrupter bottle (type WL-23318). Ross Engineering of Campbell, California builds high-voltage relays, contactors, and voltage dividers for power test and transmission work.
Vacuum relays and contactors in this class switch high-voltage circuits in power utility test labs, high-voltage test sets, X-ray and radar transmitters, capacitor banks, and induction heating equipment. The vacuum interrupter extinguishes the arc as the contacts part, which is what lets a device this size make and break at 70 KV without the contact erosion an air-break device would suffer.
The record covers three units; the photographed unit carries nameplate HAF71NC100ACUW, serial 40219-2, P/N 80117. Legacy catalog reference RH7G4902E21B20 is retained in the title for cross-reference.
Used, sold as-is. Sold as-is, surplus from King Surplus inventory in Del Rio, Texas. Same-day shipping on orders before 3:00 PM CT.
