Provided herein is a label structure for tagging a product item. The label structure includes a first graphic pattern having a first number of pixels and printed on a first portion of the label structure; a second graphic pattern having a second number of pixels and printed on a second portion of the label structure, the second graphic pattern forming an optical code readable by an optical decoding device; and shielding means capable of hiding or making visible the first graphic pattern depending on the values taken by a physical quantity to which the label structure is exposed. The first and second graphic patterns can be observed in combination, when the first graphic pattern is made visible by the shielding means.

Label structure for a product item

A low and medium voltage electrical enclosure comprising a supporting structure which defines an internal space delimited by walls forming one or more compartments housing one or more electrical apparatuses. At least one of said walls is provided with one or more venting openings that put into communication said internal space with the outside of said low voltage electrical enclosure and/or one of said compartments with a second compartment. The venting openings are provided with a cover closing a corresponding venting opening in a first&#x2014;closed&#x2014;operating condition at first predetermined temperatures and the enclosure is provided with an actuating device adapted to open said cover in a second&#x2014;open&#x2014;operating condition at second predetermined temperatures. The actuating device comprises an actuating mechanism having a Shape Memory Alloy-based (SMA-based) actuating element having a first dimension at said first predetermined temperatures reversibly changeable into a second dimension at said second predetermined temperatures, the reversible change of dimension of said SMA-based actuating element from said first dimension to said second dimension determining the reversible movement of said cover from said first&#x2014;closed&#x2014;operating condition to said second&#x2014;open&#x2014;operating condition, and vice-versa.

Low and medium voltage electrical enclosure

A low and medium voltage electrical enclosure comprising a supporting structure which defines an internal space delimited by walls forming one or more compartments housing one or more electrical apparatuses. At least one of said walls is provided with one or more venting openings that put into communication said internal space with the outside of said low voltage electrical enclosure; the venting openings are provided with a cover closing a corresponding venting opening in a first&#x2014;closed&#x2014;operating condition. The enclosure is provided with an actuating device adapted to open said cover in a second&#x2014;open&#x2014;operating condition in case of arc fault inside said internal space; said actuating device comprises an actuating mechanism having a Shape Memory Alloy-based (SMA-based) actuating element having a first dimension at first predetermined temperatures reversibly changeable into a second dimension at second predetermined temperatures. The reversible change of dimension of said SMA-based actuating element from said first dimension to said second dimension determines the reversible movement of said cover from said first&#x2014;closed&#x2014;operating condition to said second&#x2014;open&#x2014;operating condition, and vice-versa.

A bus bar for electric power distribution switchboard is disclosed, which can include a conducting body, which longitudinally extends along a principal axis and, which, seen in a transversal cross-section, has a first side and a second side transversally connected by a third side and a fourth side. The body has, on the first side, at least a first slot and a second separated slot, and wherein the first slot has a first bottom portion from which a first lateral wall and a second lateral wall protrude transversally facing to each other, and the second slot has a second bottom portion from which a third lateral wall and a fourth lateral wall protrude transversally facing to each other. Each of the first bottom portion and the second bottom portion includes two substantially straight tracts, which form an angle of less than 180&#xb0; between them.

A cabinet for an electrical switchboard includes a supporting base and a frame mounted on the supporting base. The supporting base includes a base element having a lower wall configured to rest on a bearing surface, and a first lateral wall and a second lateral wall which protrude transversally from the lower wall and face each other. The base element includes a first upper wall protruding from an upper end of the first lateral wall towards the second lateral wall, a second upper wall protruding from an upper end of the second lateral wall towards the first lateral wall, so as to extend over at least a portion of the first upper wall. The base element also includes a coupling mechanism which couples the first and second upper walls to each other for supporting a corresponding portion of the frame.
