Abstract
A disconnecting device for interrupting a direct current between a direct current source and an electric apparatus, having a current-conducting mechanical switch, a power electronics unit connected thereto, and an energy store which is charged by an arcing voltage generated on the switch by an arc as the switch is being disconnected. A pulse generator that is connected to the energy store triggers at least one semiconductor switch of the power electronics unit in such a way that the power electronics unit short-circuits the switch and the arc is extinguished.
