Abstract:
An electrical switching device including at least a nominal contact arrangement, the nominal contact arrangement at least a first nominal contact with a plurality of nominal contact fingers forming a finger cage concentric with respect to a longitudinal axis (z), and at least a mating second nominal contact. An arcing contact arrangement including a first arcing contact and a mating second arcing contact. An arcing contact finger including at its free end a first impact area in which a first contacting to the second arcing contact occurs when closing, the electrical switching device. The first impact area is formed by a first planar surface arranged at an inclination angle (α) larger than zero degrees with respect to the longitudinal axis (z).
