V4 & V7 (Single-Gap Vacuum Interrupter)
The V4 and V7 vacuum interrupters are single-gap load-breaking devices that utilize vacuum bottle technology, where no gases are vented to the atmosphere.
The new single vacuum bottle design can break loads up to 2000 Amps at 48kV and 72.5 kV; where it now replaces the original V2 and V3 multi-vacuum bottle designs.
Vacuum bottle interrupters are not in the current path during the switch closing operation, and have no fault closing capabilities.
The mechanical and electrical life of the V4 and V7 vacuum interrupter is 5000 operations at full load.
