Abstract:
1. A device for limiting leakage currents for an electrical apparatus, the device being connectable, individually, to a three-phase supply network and a single-phase supply network as a source that supplies the electrical apparatus with electrical power, the device comprising: circuitry including: wherein first electrodes of the second through fourth capacitors are connected together and to the third switch, second electrodes of the second through fourth capacitors are respectively connected to the first through third power supply lines, two of the first through third power supply lines are respectively connected to the first and second switches, and each of the first and second switches is connected to the first capacitor, wherein the circuitry is configured to wherein, in a case that the device is identified as being connected to the three-phase supply network, the third switch is closed, and wherein, in a case that the device is identified as being connected to the single-phase supply network, one of the first and second switches is closed.
