Abstract: An anchoring assembly for enclosures that includes at least one laminar screen, which has at least one rigid wire, and at least one post, for supporting the screen with vertical orientation. The assembly has at least one pin provided with a head and with a shank, the shank being configured to be inserted into a hole in the post. The assembly further includes at least one clamp that has a recess configured to receive the shank with interference. The rigid wire can be clamped in the clamp. The assembly also includes at least one at least partially threaded stem, which can be screwed into a female thread which is provided inside the pin, with consequent mutual tightening of the clamp.

Abstract: Accessory device for a low or medium voltage switching device including an outer housing, first electrical connection means adapted to electrically connect the accessory device with an auxiliary power line and first mechanical connection means adapted to mechanically connect the accessory device with a mechanical support component of the switching device. The accessory device includes a power line communication unit electrically connectable with the auxiliary power line through the first electrical connection means and adapted to communicate with outer electronic equipment electrically connected with the auxiliary power line by transmitting and receiving communication signals along the auxiliary power line.

Abstract: An accessory device for an electronic protection relay comprising: a first communication port for communication with one or more electronic devices of the electronic protection relay or operatively connected with the electronic protection relay; a second communication port for communication with one or more computerized units through the Internet; a first processing means to manage the operation of the accessory device, the first processing means being operatively coupled with the first and second communication ports. The accessory device is configured to execute a data-gathering procedure (DGP), in which the accessory device polls one or more electronic devices, which are in communication with the accessory device through the first communication port, and receives grid data (D), which are related to the operation of an electric power distribution grid including the electronic protection relay, from the electronic devices in response to the polling.

Abstract: A communication network for a low-voltage switchboard comprising three types of communication bus. The first communication bus is designed to provide a first communication channel with at least one electronic protection device. A second communication bus is designed to provide a second communication channel with said electronic protection device. At least one third communication bus (13) is designed to provide a third communication channel between said at least one protection and control unit and one or more additional electronic modules (6A, 6B, 6C, 6E, 6F). The second communication bus is associated with a second, higher user access level than the first user access level associated with said first communication bus.
