Arrangement and method for automatically configuring a magnetic drive

An arrangement for automatically configuring a magnetic drive, the arrangement comprising:

• a vacuum switching device having a movable contact and a fixed contact;
• a magnetic drive having a magnetic armature and two coils being connectable in parallel or in series, wherein said magnetic drive is configured, in a switched-on state, to exert an attractive force on said magnet armature and to move said magnet armature, said magnetic drive further having controllable switching devices for said coils;
• a transfer mechanism configured to translate a movement of said magnet armature into a movement of said movable contact toward said fixed contact;
• an actuator for said magnetic drive, said actuator configured for an input voltage;
• and
• a configuration device configured to measure the input voltage and to configure said actuator for the input voltage measured, and to connect said coils in parallel or in series by means of said controllable switching devices depending on the input voltage measured, said configuration device is configured to connect said coils in parallel for the input voltage of 90 V to 150 V and to connect the coils in series for the input voltage of 180 V to 250 V.
