Abstract
A switching apparatus is disclosed for switching a current, formed using a phase conductor and a switch arranged in the phase conductor, for the purpose of switching a transmission of current via the phase conductor. In addition, the switching apparatus includes a circuit for deriving a test current from the phase conductor via a ground conductor; a sensing apparatus for detecting the test current and an evaluation apparatus for evaluating the detected test current. A control apparatus is used to control closing of the switch arranged in the phase conductor. The evaluation apparatus is configured to detect a zero crossing for an alternating current and the control apparatus is set up to prompt closing of the switch arranged in the phase conductor in accordance with the time of the zero crossing. An embodiment reduces abrasion or wear on the switch as a result of short-circuit currents during switching-on.
