Abstract (en)

[origin: EP1764811A1] The device has an arc chute (24) with two parallel flanges placed on sides of a longitudinal mid-plane. The chute has a bottom arcing horn (34) electrically connected to a stationary contact part (20) and extends close to a rear wall. The horn receives an arc root when an arc extends from a stationary contact strip (36) towards the inside of the chute. The chute has a stack of separators (78) with notches extending in the mid-plane and regenerating separators (79) that are placed in a parallel manner and comprise metallic surfaces which cover half of the notches.
