A functional module for a switch device control is disclosed. In at least one embodiment, the functional module includes&#x2014;a communication unit having a communication interface for communicating with at least one further functional module and/or at least one coupling module,&#x2014;a control unit connected to the communication unit and designed to receive signals transmitted from the at least one further functional module and/or the at least one coupling module to the communication unit and to transmit switch commands via the communication unit to the at least one further functional module and/or the at least one coupling module,&#x2014;a first control current interface for the electric connection to a first switch device or an external energy supply unit, and&#x2014;a second control current interface for supplying control current to the at least one further functional module and/or the at least one coupling module.

Function module and coupling module for a switch device control and system for switch device control

A recording device is for recording the switch state of an electromagnetic switch device. In at least one embodiment, the recording device includes a housing, in which a plunger is movably mounted. The plunger may be moved between two mechanical end positions, wherein the end positions of the plunger correspond to the switch states of the electromagnetic switch device. A sensor device is arranged in the housing by which it may be recorded in which of the end positions the plunger is and from which a corresponding electrical signal may be emitted. The sensor device is designed to be able to record the position of the plunger without contacting the plunger.

A switching device switches at least one current phase between responsive current phase input and responsive current phase output, wherein the switching device is suitable for switching electrical current of a power circuit of an electric motor. The switching device further includes a first communication system interface for a first communication system, a second communication system interface for a second communication system, and a selecting unit for selecting whether the switching device is a master or slave in relation to the second communication system.

Switching device and system with switching device

A switching device comprising switching means for switching at least one current phase between responsive current phase input and responsive current phase output, the switching device being suitable for switching electrical current of a power circuit of an electric motor, further comprises a first communication system interface for a first communication system, a second communication system interface for a second communication system, and a selecting unit adapted to select whether the switching device is a master or slave in relation to said second communication system.

Switching device and a system comprising the same

There is described a method and a system for monitoring a protective apparatus, which is connected upstream of a switching device and is connected to the switching device via at least one main current path. The wiring complexity for monitoring of the protective apparatus is minimized. This is achieved by virtue of the fact that the sate of the protective apparatus is determined by a tap of the at least one main current path at or in the switching device by means of an evaluation unit. As a result of this direct evaluation of the switching state of the protective organ on the switching device, the wiring which until now has been required for an addition auxiliary switch on the protective device is dispensed with a possible fault source also being minimized along with the wiring complexity. For this purpose, the proposed solution is also independent of the physical design (branch-oriented or row-oriented, distance between the devices) in a switchgear cabinet.
