Abstract
A switching device unit is disclosed for switching at least two operating states of at least one consumer to an at least two-phase electrical supply system by way of switching elements. At least one embodiment of the invention specifies a switching device unit which has as simple a construction as possible and is as cost-effective and compact as possible. For this purpose, the switching device unit contains circuits for operational switching of the consumer, for implementing the tripping function for protection against overload and short circuits, wherein these circuits are integrated in such a way that the switching device unit, in particular in terms of its function as a compact reversing starter, can have a standardized width in order to be installed in a space-saving manner on a top-hat rail in a switchgear cabinet and in order to be operated.
