Embodiment Construction

[0025] The drawing shows a simplified representation of an exemplary embodiment of a pluggable device combination according to the invention for protection against grid overvoltages or overcurrents. The pluggable device combination includes an approximately U-shaped device base 1 and a plug-in module 2 that can be inserted into the device base 1 . The device base 1 has a base housing 3 with a recess 4 for receiving a plug-in module 2 . In addition, in the two legs of the device base 1 there are connected terminals (not shown here), for example screw terminals, for connecting conductors of the network to be protected. The connecting terminals are electrically conductively connected to the plug contacts, via which the plug-in module 2 can be electrically connected to the device base 1, for which purpose the connecting plug-contacts corresponding to the plug-in contacts are removed from the plug housing of the plug-in module 2. 5 out. As is customary in the prior art, the plug ...

Abstract

The presnet invention relates to a plug-in appliance combination with an appliance base and a plug-in module. The appliance base has a base housing with a recess for receiving the plug-in module, a linkage terminal for a conductor of a power grid to be protected, and a plug-in contact. The plug-in module has a plug housing, A protective element arranged in the plug-in housing, and a linkage plug-in contact corresponding to the plug-in contact. In the apparaut combination, unlocking and replacement of the plug-in module are executed thereby. At least one recess delimiting wall of the appliance base is provided with a flexible locking arm, at least one end side of the plug housing is provided with a locking recess, an unlocking element is arranged on the end side, wherein in the fully plugged state of the plug-in module in the recess, the locking arm is not deflected in a first, lower position of the unlocking element, so that the free end of the locking arm in the detent recess; engages, during the locking arm is deflected in a second, upper position of the unlocking element so that the free end of the latching arm does not extend into the locking recess.

Description

technical field [0001] The invention relates to a pluggable device combination (Gerötekombination) for protection against grid overvoltages or overcurrents, with a device base and at least one plug-in module that can be plugged onto the device base, wherein the device base The socket has a base housing with recesses for receiving the plug-in modules, connection terminals for the conductors of the electrical network to be protected, and plug contacts connected to the connection terminals. The plug-in module has a plug housing; a protective element arranged in the plug housing, in particular a lightning current and / or overvoltage conductor; and coupling plug contacts corresponding to the plug contacts. Background technique [0002] Of particular importance for the operational reliability of electrical installations, machines and installations is a long-term, defined supply of energy. For example, in order to prevent the downtime of equipment or equipment parts or to keep the ...
