Depending on the version, the load break switch and/or the earthing switch are operated manually or electrically.
Manual operation is achieved by means of a solid operating handle, which was designed in such a way that even cubicles placed against a wall can easily be switched. Very little strength is needed for the manual operation.

The opening and closing device of the load break switch and the earthing switch have been fitted in one drive mechanism. Both switches have their own, separate operating shaft. The operating shafts are mechanically interlocked to prevent unadapted switching operations. Hitting bolts connected to a shaft on the top of the fuse ensures that the load break switch opens, in case of fuse blowing.

On the front panel, there is a single line diagram, which indicates in a diagrammatical way the current flow and the various positions of the components of the concerned cubicle.
