Abstract: An aim of an embodiment of the invention is to better use the time forecast for switching off an overload protection device. For this purpose, the determination of a trigger-release time reserve is related to a corresponding evaluation. In such a manner, it is possible, for example to dynamically determine whether a desired process can be carried out in the total length thereof or automatically disjointed, thereby making it possible to generate corresponding warning signals.

Abstract: A plug-in connection system is disclosed which is economical to produce, is compact, is easy to handle and/or which connects to a module in an electrically reliable manner. A plug-in connection device includes locking hooks which are provided includes locking hooks which are provided with unlocking elements. As a result, the locking hooks can be maintained in an unlocked position such that the plug-in connection can be released in a simplified manner. The unlocking elements may project in an essentially non vertical manner over the housing of the connection device or in an extrinsically vertical manner over the housing of the connection device. The total space required for the plug-in connection system is reduced, thereby ensuring that the module is connected in an electrically reliable manner.
