1. A device combination for protecting electrical networks against overvoltages or overcurrents, comprising an essentially U-shaped base and at least one plug-in module, which can be plugged or pushed onto the base, wherein the base has connection terminals for connecting to the respective network and also has plug-in contacts, which are connected to the connection terminals and are complementary to mating plug-in contacts or contact tongues of the plug-in module, and the plug-in module has a housing which accommodates one or more lightning and/or overvoltage arresters, and the mating plug-in contacts or contact tongues pass through a floor side of the housing, comprising:
means for changing the position and the distance between the plug-in contacts and mating plug-in contacts or contact tongues from a working position, with a closed, surge-current-resistant electrical connection between the plug-in module and base, to an idle position, in which the plug-in contacts and mating plug-in contacts or contact tongues are located in an isolation/disengagement position, with a distance between them corresponding to a necessary electrical separation distance and necessary creepage distances and clearances, the plug-in module nevertheless still being retained or fixed on the base,
wherein the plug-in module is rotatable or pivotable, wherein a selection can be made between the working position and the idle position by pivoting or rotating the plug-in module.
