Due to the representational architecture of an electrical installation arrangement 8, a good overview of the processes within the relevant installation, but above all also of the status of the installation and the individual branches, can be achieved at a central or decentralized location. Due to the good overview of the electrical installation assembly 8 can be compensated by selectively switching off individual protection devices on the
- the individual protection switching devices are each assigned a priority level. As a result, for example, a protective switching device to which a safety-critical consumer is connected, a high
- a switch-off command is transmitted from the control and / or control unit 13 via the data interfaces 6 of the individual devices to the protection device 1. Subsequently causes the trigger 4 of the protective device 1, an opening of the switching contacts 2, 3 of the protective device 1, wherein such the electrical load 10 out of service is taken.
- the electrical switching path 20 of the protective switching device 1 is closed by the switching unit 23 of the protective switching device 1, wherein a deceleration command from the control and / or control unit 13 via the first to decommission the electrical load 10 Data interface 6 is transmitted to the protection device 1, wherein subsequently the electrical switching path 20 of the
- Protective device 1 is separated by the turn-off unit 22 of the protective device 1 and so the electrical load 10 is taken out of service.
