Abstract: The present disclosure relates to an arc extinguishing chamber (170) for a switching device (100) comprising an arcing contact unit (160, 150, 140) and a main contact unit (165, 130, 120), each of the contact units including a movable contact (150, 130) and a stationary contact (140, 120), the arc extinguishing chamber (170) comprising a plurality of arc splitters (172) disposed with a distance to each other, each of the arc splitters (172) including a pair of arms and the plurality of arc splitters is arranged to form a passage (P) for the movable arcing contact, wherein the passage has a height. The height of the passage is adapted such that, when a current is switched off/ interrupted, the separation distance (h) of the arc contacts is longer than the one (H) of the main contacts and the movable arcing contact moves within the passage during the most part of the separation distance (h).

Abstract: 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).
