Interrupter device for interrupting a direct current

An interrupter device for interrupting a direct current between a direct current source and an electrical device, the interrupter device comprising:

• a semiconductor switch;
• and
• a mechanical switch that has a first fixed contact, a second fixed contact, and a contact bridge that is adapted to be moved between a first position and a second position, wherein in the first position, the first fixed contact and the second fixed contact are electrically contacted via the contact bridge, and in the second position, the contact bridge is spaced apart from the first fixed contact and the second fixed contact,
• wherein the contact bridge and the first fixed contact are electrically contacted to the semiconductor switch, which blocks current when the contact bridge is in the first position, and
• wherein a control input of the semiconductor switch is connected to the mechanical switch such that an arc voltage generated as a result of an arc across the switch connects the semiconductor switch so as to conduct a current when the contact bridge is moved into the second position.
