A connecting system includes an electromagnetic switchgear, especially contactor, and a connector. In at least one embodiment, the system makes it easier to connect auxiliary and control lines. For this purpose, the connecting system, in at least one embodiment, includes at least one electromagnetic switchgear, especially a contactor. The switchgear includes a plurality of auxiliary contact connections and a coil connection terminal block. The coil connection terminal block is configured in such a manner that the coil connections lie in a plane with at least one auxiliary contact connection. The connecting system also includes, in at least one embodiment, a connector for simultaneously contacting the coil and auxiliary contact connections of one or more switchgears which connections lie in one plane. The connector has an internal wiring for electrically interconnecting the coil and/or auxiliary contact connections.

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.

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. The electromagnetic switching device also has an actuating apparatus having an actuating element which interacts with the moving contact element and can be moved between an operating position and a safe position. 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.

A method and a device for secure operation of a switching device including at least two main contacts which can be switched on and off and include contact pieces and a displaceable contact bridge, and a control magnet having a displaceable anchor. The method may include producing an electric control signal to release a contact breaking device when the control magnets are switched on and off. The emitted control signal lies outside the ON state of the switching contact during the regular operation of the switching device and releasing the contact breaking device in defective operation of the switching device if the switching contact remains in the ON state when the control magnets are switched on or off. The switching contact may connect through the control signal to release the contact breaking device.

In a the method for adjusting thermal overload cutouts, after a synchronization of bimetallic strips and optionally a preadjustment of a cutout mechanism, the bimetallic strips are acted upon by current for a specific time, at the end of which the actual adjustment procedure takes place. In this, a residual cutout distance still remaining between the bimetallic strips and a mechanical shutoff point is reduced by zero by an apparatus. This adjustment method eliminates repeat testing with time-consuming cooldowns.
摘要:
A method and a device for the secure operation of a switching device are disclosed, including at least one main contact which can be switched on and off and which includes contact pieces and a displaceable contact bridge, and also at least one control magnet which includes a displaceable anchor. The anchor acts upon the contact bridge when it is switched on or off such that the corresponding main contact is opened and closed. In at least one embodiment, the method includes: a) the displaceable contact bridge of the at least one main contact recognizes when an opening point has been exceeded after being switched off, and b) the additional operation of the switching device is interrupted, according to a predetermined duration of time, when the opening point is not exceeded.

A method and a device are disclosed for the secure operation of a switching device including at least two main contacts which can be switched on and off and which include contact pieces and a displaceable contact bridge, and at least one control magnet which includes a displaceable anchor. The anchor acts upon the contact bridge when switched on and off such that the corresponding main contact is opened or closed. A switching contact, which has an on and off state corresponding to the closing and opening position of the anchor, is provided. In at least one embodiment, the method includes the following steps: a) an electric control signal which is used to release contact breaking device is produced when the control magnets are switched on and off. The control signal is emitted such that it lies outside the ON state of the switching contact during the regular operation of the switching device and b) the contact breaking device are released in the defective operation of the switching device if the switching contact remains in the ON state when the control magnets are switched on or off, wherein the switching contact connects through the control signal in order to release the contact breaking device.
