Plug-in terminals - Are plug-in terminals of the same quality as screw terminals?

Yes, the Niko plug-in terminals undergo a whole battery of tests. These tests have shown that the terminal stays within the limits of the standard in the event of heating because of voltage drop. Because of this, the Niko plug-in terminals have a long life span. Moreover, the wire is fixed tightly. Because the terminal release is at the front of the mechanism, it is impossible for the wire to push the release and accidentally come loose.
