ABSTRACT:
The disclosure relates to an electrical breaker device with double movement of its contact systems. An auxiliary gear is designed for driving the second contact systems such that the holding means for holding the rack and pinion gear and the guiding means for slide guiding and slide contacting the auxiliary-gear-driven arcing contact piece are constructed integrally in a monoblock. Embodiments, among others, relate to: a pusher guide slide bearing recessed in the arcing contact piece that is driven by the auxiliary gear; a minimal configuration of the toothed rack drive with only one cogwheel; and a limit stop for defining an end position for the auxiliary-gear-driven arcing contact piece. Advantages, among others, are: auxiliary gear with reduced number of parts, and simplified mounting and adjustment.
