Problems solved by technology
In this case, the status of the protective device is signaled via an additional auxiliary switch installed on the protective device, however, the voltage at the switching device cannot be identified in this way
With such high wiring costs, these conventional solutions are not only time-consuming and costly, but also bury possible sources of failure during the wiring process

Embodiment Construction
[0024] figure 1 and figure 2 In each case an adapter 1 is shown with contact connections 2 for the evaluation unit and lugs 3 , by means of which the main current path can be tapped in the connection area of the switching device. For assembly, the adapter 1 is plugged onto the switching device, and in the embodiment shown, the fixing and contacting of the main current path is achieved by means of a screw connection. The two adapters 1 are shaped to match the different switching devices, see Figure 6 and Figure 7 . Both adapters 1 have three lugs 3 that can tap the three main current paths, wherein no changes need to be made on the switching device for tapping in the connection area. The evaluation unit can determine the state of the protective device connected upstream of the switching device by voltage measurement and can be connected to the contact connection device 2 for the evaluation unit (that is to say, different adapters 1 have the same contact for the evaluat...

The invention relates to an adapter for producing an electrically conductive connection between at least one main current path of a switching device and an evaluation unit for determining the state of a protective apparatus, which is connected upstream of the switching device. In order to make it possible to monitor a protective apparatus which is connected upstream of the switching device with minimum wiring complexity, the invention proposes an adapter for producing an electrically conductive connection between at least one main current path of a switching device and an evaluation unit for determining the state of a protective apparatus which is connected upstream of the switching device, wherein the adapter can be connected mechanically to the switching device and has contact interfaces for connection of the evaluation unit. As a result of the direct evaluation of the switching state of the protective organ on the switching device, the wiring which until now has been necessary for an additional auxiliary switch on the protective device is dispensed with, a possible fault source also being minimized with the wiring complexity.
