Operating lever for earthing switch:
•
With the operating lever, the switching process at the feeder earthing switch can only be executed in
turning direction.
•
The turning movement into the opposite direction has a freewheel and does not move the feeder
earthing switch; the operating lever works like a ratchet spanner.
•
The feeder earthing switch is operated either clockwise or counter-clockwise according to the
switching function.

To use the operating lever, two instruction labels show the turning direction for the corresponding
switching function.
