Abstract: Electrical switching device having a housing, at least two switching chambers within the housing with contacts to interrupt at least one current path, an arc extinguishing device for each switching chamber, and at least one guide channel within the housing, which directs the arc gas exiting the arc extinguishing device towards at least one of the exhaust openings to allow the arc gases to exit the housing, whereby each switching chamber has a guide channel, and whereby the guide channels of the different switching chambers are separated from each other.

Abstract: A switching device includes at least a first current path and a second current path, each of which have a first connection and a second connection, whereby the first connections are arranged on the first side of the switching device and the second connections on the second side of the switching device, each current path has at least one contact pair, that has a first contact and a second contact, whereby at least the second contact is arranged on a contact member that is movable to the first contact and whereby in the switched-on status of the switching device, both the contacts are in contact with each other, each contact pair has at least one extinguishing device, whereby the extinguishing devices of both the current paths are arranged in a direction from the first connections to the second connections, behind one another and at least partly covering each other.

Abstract: A polarity-independent switching device for carrying and disconnecting high DC currents has a gastight, encapsulated, electrically insulating housing which can be filled with an insulating gas, and at least one pair of contacts disposed in the housing and made up of a fixed contact and a mobile contact. The two contacts are in contact with each other in a switched-on state of the switching device and are not in contact in a switch-off state of the switching device. An arc driver arrangement is included which generates a magnetic field at least in the region of the pair of contacts, as well as a first arc routing arrangement with which an arc produced between the contacts is guided in a first current direction to a quenching area arranged at a distance from the contacts.

Abstract: A contactor for DC operation includes a first and a second contact that are fixed contacts and a contact bridge that has a third and a fourth contact. The contact bridge, in a closed position, provides a tactile contact between a first contact pair, which comprises the first and the third contact, and between a second contact pair, which comprises the second and the fourth contact. The contact bridge is movable via a guide along a direction of movement. A magnet arrangement is configured to generate an electromagnetic force on an electric arc, which arises on opening the contacts. The contact bridge has at least one recess, which is arranged between the guide and the third contact. The recess is configured to provide an opening at the contact bridge through which the arc, generated at the third contact, is deflected in the direction of movement of the contact bridge.

Abstract: An electromagnetic switching device with a multipart housing. The magnet core of the switching device, including the coil, is accommodated in one of the housing parts. Identical connecting modules are provided for each outer terminal of the device. These connecting modules can be slipped on on the top side of the housing part in which the magnet core is accommodated, in the area of the four corners of said housing part. A blank module is configured externally in the same way and can be slipped on on the corner of the housing part which is not occupied by a connecting module.
