Model Composition and Meaning：
Load Break Switch Closing Operation
Insert the operating handle into the lower hole of the closing operation shaft (bottom right corner) and rotate 180° clockwise. The mechanism drives the contacts to quickly perform the load switch closing operation.
Load Break Switch Opening Operation
Rotate the operating handle 180° counterclockwise to complete the operation.
Load Break Switch Earthing Operation
Insert the operating handle into the earthing operation shaft hole (top right corner) and rotate 180° clockwise. The mechanism drives the contacts to quickly perform earthing closing. To perform the earthing switch opening operation, simply insert the operating handle into the earthing operation shaft and rotate 180° counterclockwise.
