    In the case of large short-circuit currents, the gas between the arcing contacts (1) and (7) is heated by the arc energy. Thus, the pressure in the heating volume (11) increases. When the current passes through zero, the gas flows back from the heating volume (11) through the nozzle (9) and quenches the arc. The valve (3) of the contact cylinder
