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.

Abstract: A system for short-circuiting or grounding low-voltage and/or medium-voltage installations. The system includes at least one fault detection unit for detecting an arc and at least one signal-processing unit for processing signals from the at least one fault detection unit. The signal-processing unit is or can be connected to the fault detection unit for signal transmission. The system further includes at least one control unit which is or can be connected to the signal-processing unit for signal transmission, an electrical energy storage device in or on the control unit, and at least one fast-switching switching element having a mechanical energy store.

Abstract: Disclosed is a switching device comprising a vacuum tube and an adjustable drive for opening and closing the contacts of the switching device. The switching device also comprises a sensor for detecting physical properties of the operating site of the switching device. The detected physical property adapts the adjustable drive for opening and closing the contacts to the operating site.
