Summary: | An electrical switching device includes: a main contact arrangement including a fixed contact and a movable contact, a plurality of splitter plates, each having a loop structure, the splitter plates being coaxially stacked with respect to their loop structure to form a stack, wherein one splitter plate is a first outermost plate and another splitter plate is a second outermost plate, a first arc runner electrically connected to the second outermost plate and a second arc runner electrically connected to the first outermost plate, the first and second arc runners being configured to direct a main arc from the main contact arrangement to the stack to thereby split the main arc into a plurality of secondary arcs between the splitter plates, and a first drive coil electrically connected to the second arc runner and to the movable contact or to the first arc runner and to the fixed contact. |
