Abstract:
A switching device suitable for DC operation includes at least a pair of contacts having a first and second contact, wherein at least one of the two contacts is mobile and the two contacts are in contact with one another in a switched-on state and are not in contact with one another in a switched-off state, having an arc driver arrangement which generates a magnetic field at least in the region of the pair of contacts, and comprising a first arc guiding arrangement by which an arc which is produced between the contacts is guided in a first current direction to a quenching device for quenching the arc, wherein a second arc guiding arrangement is provided, by means of which an arc which is produced between the contacts is guided in a second current direction, which is opposite the first current direction, to said quenching device for quenching the arc.
