摘要:
The invention relates to an electromagnetic switching device, in particular a contactor, comprising a switching device housing (2) and a plug-in module which can be inserted into the latter and which contains a coil form (12) for a coil. A tripping element (60) is mounted on a housing section (40) of the plug-in module (4). Said element is designed to mechanically actuate the contact unit (30) of an electric switch (24) for producing an economy connection. The switch (24) is mounted on a support structure (printed-circuit board (22)) that is located in the plug-in module (4), with a supporting contour (70) of said switch adjoining a bearing contour (72) of the housing section (40).
摘要:
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.
摘要:
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.
