Abstract
In the case of an electrical switching installation having a plurality of switches for each phase, for example an earthing switch (1), a disconnector (2) and a circuit breaker (3), at least one of the switches, for example the earthing switch, has a motor drive (10) and a detachable mechanical coupling (5) which transmits the drive movement. The coupling (5) can be disengaged by operation of the disconnector (2) when it is being connected, so that, when the disconnector (2) is being connected, the earthing switch (1) cannot be moved into the earthing position, and this prevents high-voltage potential being connected to the earth potential. <IMAGE>
