Abstract
An apparatus for switching in a DC voltage mains has a switching device for interrupting the flow of current in at least one line of the DC voltage grid. The switching device is connected into the line of the DC voltage grid by way of a first and a second connection. An attenuation member absorbs energy from the applied terminal voltage. The attenuation member has a first and a second node that are electrically connected via an attenuation element, an electrical connection from the first node to the first connection via a first controlled or uncontrolled switching element, and an electrical connection from the first node to the second connection via a second controlled or uncontrolled switching element.
