    Abstract: A contact unit for a switching device includes: a first fixed contact; a second fixed contact; a contact bridge; a first movable contact and a second movable contact that are arranged at the contact bridge; a first arc extinguishing chamber, a second arc extinguishing chamber, and a third arc extinguishing chamber; and an arc guiding system. The first fixed contact is in contact with the first movable contact and the second fixed contact is in contact with the second movable contact in a switched-on state of the contact unit. The first fixed contact is free of contact with the first movable contact and the second fixed contact is free of contact with the second movable contact in a switched-off state of the contact unit. The first and the second arc extinguishing chamber and the arc guiding system in coordination with each other extinguish a first arc.

    Abstract: A switching device includes: a first fixed contact; a second fixed contact; a contact bridge; and a first movable contact and a second movable contact that are arranged at the contact bridge. The first fixed contact is in contact with the first movable contact and the second fixed contact is in contact with the second movable contact in a switched-on state of the switching device. The first fixed contact is free of contact with the first movable contact and the second fixed contact is free of contact with the second movable contact in a switched-off state of the switching device. A load current that flows through the contact bridge between the first movable contact and the second movable contact in the switched-on state has a curved path. A path of the load current flows through the contact bridge between the first movable contact and the second movable contact.

    Abstract: A switching device includes an arc extinguishing chamber, an orifice for outflow of the gases from the arc extinguishing chamber, and a multilayer wire cloth or fabric having at least a first wire layer and a second wire layer. The first wire layer and the second wire layer have a respective cloth or fabric structure including respective warp yarns and weft yams. The first and second wire layers are disposed in a stacked configuration in the orifice such that a weaving direction of the warp yams of the first wire layer is rotated by an angle in relation to a weaving direction of the warp yarns of the second wire layer, and a weaving direction of the weft yarns of the first wire layer is rotated by an angle in relation to a weaving direction of the weft yarns of the second wire layer.
