Abstract: An arrangement automatically configures a magnetic drive. The arrangement contains a vacuum switching device having a movable contact and a fixed contact, and a magnetic drive having two coils which are switched in parallel or in series. The magnetic drive, when switched on, exerts an attractive force on an armature and moves the armature. A transmission mechanism is configured to translate a movement of the armature into a movement of the movable contact towards the fixed contact. An actuating device is provided for the magnetic drive, which actuating device can be configured to an input voltage. The magnetic drive has controllable switching devices for the coils, and a configuration device is configured to measure the input voltage and to configure the actuating device to the measured input voltage, and to connect the coils by use of the controllable switching devices depending on the measured input voltage.
