Abstract: An electromagnetic switching device includes an electromagnetic drive device and at least one electrical contact that, when a starting current is applied to the drive device, can be transferred by the drive device from a disconnect position (contact opened) into a bridging position (contact closed). When the switching device is fully installed, the contact can be blocked in the disconnect position and can be mechanically blocked in the disconnect position by an arresting element that can be connected to the switching device. As a result, the contact remains in the disconnect position even when the starting current is applied to the drive device.

The switchgear includes a pre-mounted structural component provided with a holder and a screw with a washer assembly which is held by the holder and forms, together with a connection part, a clamping point for a conductor connection created by means of a ring shoe lug. The holder can be displaced between an open position and a closed position of the clamping point, and is subjected to the action of a spring element that holds it in the open position when the clamping point is released.

Abstract: An electromagnetic switching device includes an electromagnetic drive apparatus and has a moving contact element which can be operated by this drive apparatus. The moving contact element can be switched between a bridging position, which connects a pair of stationary contacts, and a disconnected position, which disconnects the stationary contacts.

In the operating position, the moving contact element can be switched by the electromagnetic drive apparatus between the bridging position and the disconnected position. Further, by movement of the actuating element to the safe position, the moving contact element can be blocked from moving from the bridging position to the disconnected position, and can be blocked in the disconnected position.

Abstract: In a vacuum contactor, the armature is initially deflected from an armature rest position through an initial movement distance, and then through a driving movement distance to an armature operating position when a pull-in current is applied to a drive coil. An operating element is deflected from an element rest position to an element operating position by the armature only while the latter is passing through the driving movement distance. This makes it possible to achieve a good tripping characteristic of the vacuum contractor.

Abstract: A device in which a triggered switching device (1), for example a contactor, may be maintained in its ON position even if the power supply is interrupted. The invention includes a mechanical locking system having a pawl (11), which is held in a bearing (12). When the switching device (1) is triggered, the pawl (11) engages under the loading of spring force in a recess (5) in a contact carrier (4). It is possible via an unlocking device (7) to actuate an angle lever (16) which pivots the pawl (11) and releases the contact carrier (4). Unlocking can also be performed by hand via an ON-OFF indicator (23) of a second contact carrier (8). The bearing (12) may be shape-coded to ensure that it is installed properly oriented in the openings (13, 14) of the side walls (3, 6) of the switching device (1) and the locking device (7).

Abstract: A switchgear unit comprising two switching devices (1, 2) which are provided with a reversing combination, which switchgear unit is of simple design and allows easy assembly and disassembly by the customer. The reversing combination comprises an assembly which is composed of a support (3) and an anchor (4) and is inserted into slots (7, 8) in connecting side walls (5, 6) of the switching devices (1, 2). The anchor (4) prevents the contact carriers (10) of the switching devices (1, 2) from being released at the same time and, when one of the switching devices (1 or 2) is switched on, prevents the contact carrier (10) of the other switching device (2 or 1) from being released.
