Abstract (en)

[origin: EP0255008A1] An automatic cut-out has an additional arc loop in the region of the contact point (41) which is formed by an arc conducting rail (16, 33) and an additional conducting rail (31), which are connected to one another by means of rectangular connecting lines (35, 36, 37) which connect essentially laterally adjacent to the arc conducting rail and are located essentially in the region of the switched-off position of the moving contact piece (20). In this way, after opening of the contact point (41) and commutation of the base of the arc from the moving contact piece (20) to the arc conducting rail (33, 16) currents are made to flow in each case parallel and in the same direction with respect to one another both in the additional conducting rail (31) as well as in the arc conducting rail (33, 16), by which means it is achieved that the base of the arc is accelerated into an arc quenching plate stack. <IMAGE>
