Basic block for mounting of installation devices

An expansion connection module is disclosed for connecting to at least two coil connectors of an electromagnetic switching device, in particular a contactor. In at least one embodiment, the expansion connection module includes a housing; at least one fastening device for fixing the expansion connection module to the electromagnetic switching device or to a switchgear unit positioned adjacent to the electromagnetic switching device; at least two connection openings and at least two terminal blocks associated with the at least two connection openings for the purpose of connecting voltage supply lines; and at least two flexible leads for electrically connecting the terminal blocks of the expansion connection module to the at least two coil connectors of the electromagnetic switching device.

There is described a switching device whose disconnection cause can be identified, and a method for displaying the disconnection cause of a switching device. The switching device has a switch latch for mechanical activation of the switching device, a first tripper for overload protection, a second tripper for short-circuit protection, and a handle for activating the switch latch. The switching device is embodied in such a way that the handle is moved to a first position or a second position if the first tripper or second tripper is tripped, with the first position and the second position being different.

Switching device with switch latch

The invention relates to an electromagnetic switching device, in particular a contactor, comprising a switching device housing () and a plug-in module which can be inserted into the latter and which contains a coil form () for a coil. A tripping element () is mounted on a housing section () of the plug-in module (). Said element is designed to mechanically actuate the contact unit () of an electric switch () for producing an economy connection. The switch () is mounted on a support structure (printed-circuit board ()) that is located in the plug-in module (), with a supporting contour () of said switch adjoining a bearing contour () of the housing section ().
