A direct current circuit breaker has a first to fifth node. A first breaker is arranged between the first node and the fourth node, and a second breaker is arranged between the fourth node and the third node. A parallel circuit of a commutator device is arranged parallel to an energy absorber between the fourth node and the fifth node, and a switch is arranged in series to the parallel circuit. A series circuit containing a semiconductor switch and a resistor is arranged between the second node and the third node. |
