<p>A power switch installation has a power switch which contains a pole unit and a switch drive, the disconnecting functions being ensured by driving the complete power switch or by rotating the pole unit relatively to the switch drive or by a separate disconnecting switch. In the power switch, the pole unit is designed, relatively to the switch drive (SA), as a separate pole module which can be axially moved on the insertable cartridge (EC) by the force transmission module (KM) of the switch drive (SA), so that the disconnecting function for the power switch installation is ensured by interrupting the load current circuits. Such power switch installations are used to switch off the energy supply, preferably of industrial plants.</p> |
