    Abstract: The invention relates to a heavy-duty circuit breaker which can be filled with a quenching gas and which contains a first displaceable arcing contact piece (1), a second displaceable arcing contact piece (2), a drive for driving the first arc contact piece (1) and an auxiliary drive (3) for driving the second arc contact piece (2). A light arc (4) is, optionally, present between the arc contact pieces. The heavy-duty circuit breaker comprises a heating chamber (11) for temporally storing quenching gas which is heated by the arc (4), and an insulating nozzle (5), which is constricted on the cross-section (6) in order to guide a quenching gas flow, which is connected to the heating chamber (11) by means of a channel (7). The constriction of the cross-section (6) is at least partially closed by a damn by one of the two arc contact pieces (2) which may also be displayed as a damn contact piece. The auxiliary drive (3) is embodied in such a manner that during a switching off step the direction of displacement of the second arc contact pieces (2) are reversed from a counter direction to the same direction of the two arc contact pieces (1, 2), when the constriction of the cross-section (6) is no longer at least partially closed by the damn contact piece (2). Advantageously, the mechanism is a mechanism (3) which is driven by the driven.
