An overcurrent circuit breaker is arranged inside an approximately cube-shaped, two-part insulating housing (1), comprising a chassis section (2) and a locking section (3). Located between the parallel side walls (4, 5) of the housing sections (2 , 3) is a switchgear with a contact bridge (13) , the movement of which is guided parallel to the side walls (4, 5). Essentially, it extends in longitudinal direction at a right angle to the side walls (4, 5) and while in the on position between two fixed contacts (14, 15) that are fastened inside the housing and are positioned on both sides of the movement plane for the switchgear. The fixed contacts (14, 15) are flat pieces akin to a knife blade. They fit against the side walls (4, 5) and respectively form a contact point (16, 17) with their narrow, knife-blade type edges facing the contact bridge (13). With their rear sides (18, 19) opposite the contact points (16, 17), the fixed contacts (14, 15) fit against a flank wall (12) of housing (1). As a result of this, the fixed contacts (14, 15) are positioned especially space-saving in the corners of housing (1).
