Abstract: An accessory device for a low-voltage switch is provided. The accessory device includes a power supply arrangement for providing a power supply to feed an electronic device onboard said switch, said power supply arrangement including a magnetic core, which forms a first magnetic circuit configured to be enchained with a primary winding conductor, and a first secondary winding conductor, which is wound around said magnetic core, and a current detection arrangement for providing detection signals indicative of a current flowing along said primary conductor. The magnetic core of said power supply arrangement and said current detection arrangement are arranged next to each other. Said accessory device includes one or more magnetic shield elements, which are interposed between said magnetic core and said current detection arrangement.

Abstract: An electronic device for low-voltage electrical installations is provided. The electronic device includes a first operational unit having a first insulating housing, a data processing arrangement accommodated in the internal volume of the first operational unit and configured to receive and process detection signals indicative of one or more physical quantities and provided by one or more sensors, a flexible belt of magnetic material having an intermediate portion and opposite first and second end portions, a power supply arrangement configured to feed the data processing arrangement by harvesting electric energy from a magnetic field generated by a current flowing along the current carrying conductor, and a second operational unit configured to couple mechanically, in a removable manner, the first and second end portions of the belt of magnetic material one to another to secure the electronic device to the current carrying conductor.
