Abstract
Switching device () for operating at least one load, comprising at least one switching unit (), which switches a tapped current phase (L) to a load (---) connectable to the switching unit () to supply said load with current and which has a measurement unit (C;C;C) which measures a current phase progression of the at least one current phase (L); a local control unit (), which after receiving a control command from an external control system () actuates a semiconductor switch (B;B;B) of the switching unit () in such a way that the semiconductor switch (B;B;B) switches at a zero of the current phase (L) measured by the measurement unit (C;C;C), and a local monitoring unit (), which evaluates the current phase progression, measured by the measurement unit (C;C;C), of the at least one current phase (L) to detect an operational deviation from a normal current supply to the associated load (---) connected to the switching unit (), and reports any detected operational deviation.
