The NBS mitigates this safety hazard, from the offneutral position, by utilizing a current limiting resistor to lower the circulating current within the regulator series winding.

The NBS offers two standard disconnect methods: By-Pass and Open Gap which ensures proper switching with a spring toggled switching mechanism. All units are fully assembled, factory adjusted and ready to install on single or dual crossarms with either hookstick or reciprocating controls.

Features:
Eliminates Regulator Switching Outages
Safe Off-Neutral Switching
Protects Personnel and Equipment
50 Years of Field Applications
Unmatched Safety Performance
Built for Reliability - US Made


 

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 46 kV - 69 kV (48 kV - 72.5 kV) ; where it now replaces the original V2 and V3 multi-vacuum bottle designs. The V4 and V7 only weighs 16 pounds and approxinately 18 inches long.  Vacuum bottle interrupters are not in the current path during the switch closing operation, and have no fault closing capabilities. The V4 and V7 vacuum interrupter is rated for 5000 operations.
