Abstract

A system for short-circuiting or grounding low-voltage and/or medium-voltage installations. The system includes at least one fault detection unit for detecting an arc and at least one signal-processing unit for processing signals from the at least one fault detection unit. The signal-processing unit is or can be connected to the fault detection unit for signal transmission. The system further includes at least one control unit which is or can be connected to the signal-processing unit for signal transmission, an electrical energy storage device in or on the control unit, and at least one fast-switching switching element having a mechanical energy store.
