Abstract

An overcurrent circuit breaker arranged inside an approximately cube-shaped, two-part insulating housing, having a chassis section and a locking section. Located between the parallel side walls of the housing sections is a switchgear with a contact bridge, the movement of which is guided parallel to the side walls and which extends in essentially longitudinal direction at a right angle to the side walls and while in the on position between two fixed contacts that are fastened inside the housing and are positioned on both sides of the movement plane for the switchgear. The fixed contacts are flat pieces akin to a knife blade and fit against the side walls and, respectively, form a contact point with their narrow, knifeblade type edges facing the contact bridge. With their rear sides opposite the contact points, the fixed contacts fit against a flank wall of housing. As a result of this, the fixed contacts are positioned in an especially space-saving manner in the corners of housing.
