Abstract
A switching device for breaking an electric current including a main contact carrier, movable and stationary main contacts, the movable contact attached to the main contact carrier, an arcing contact carrier, a movable and stationary arcing contacts, the movable arcing contact attached to the arcing contact carrier and the stationary arcing contact arranged in parallel with the stationary main contact, and an actuating unit for the main and arcing contact carriers between open and close position at an actuating distance, wherein there are separation distances between the stationary and movable contacts of the main and arcing contact units respectively when the current is interrupted. The switching device further includes a first rack and a first gear for actuating the arcing contact carrier so that, when interrupting the current, a separation distance between the arcing contacts is longer than a separation distance between the main contacts.
