A multi-pole plug assembly, in which the positions of a first contact element and a second contact element can be exchanged by means of a turning device is disclosed. The first and second contact elements can be different in terms of their plugging compatibility, for example, in that they are configured as contact pins of different diameters. In addition or alternatively, the first contact element can be connected to an outer conductor, and the second contact element can be connected to a protective conductor or a neutral conductor. The plug assembly can be embodied as a four-pole plug and configured in such a way that the first and second contact pins can adopt the positions 3h and 6h (or vice versa) in relation to a distinctive nose. Within the scope of DIN Standard EN 60309-2, two electrically similar configurations can be realized in this way.
