摘要： The present disclosure relates to switching device (1, 100, 200) for breaking an electric current comprising a main contact carrier (65, 165, 265), a movable main contact (30, 130, 230) and a stationary main contact (20, 120, 220), wherein the movable main contact (30, 130, 230) is attached to the main contact carrier (65, 165, 265), an arcing contact carrier (60, 160, 260), a movable arcing contact (50, 150, 250) and a stationary arcing contact (40, 140, 240), wherein the movable arcing contact (50, 150, 250) is attached to the arcing contact carrier (60, 160, 260) and the stationary arcing contact (40, 140, 240) is arranged in parallel with the stationary main contact (20, 120, 220), and an actuating unit (10, 110, 210) for actuating the main and arcing contact carriers (65, 165, 265; 60, 160, 260) from an open position to close position or vice versa at a 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 (90, 190, 290) and a first gear (80, 180, 280) for actuating the arcing contact carrier (60, 160, 260) so that, when interrupting the current, a separation distance between the arcing contacts (50, 150, 250; 40, 140, 240) is longer than a separation distance between the main contacts (30, 130, 230; 20, 120, 220).
