<p>The invention relates to a distribution and protection switchboard for electrical installations, which includes a rail (30) fixed to a box-like housing (2) and on which modular automatic switches (32) are snap-mounted. These latter are electrically connected simultaneously by means of an electrically conductive bar (5) provided with contact blades (8) interposed between them and the back wall (3) of the housing. Advantageously this bus bar (5) is coupled in a removable manner and slidable longitudinally of a support (20, 22) fixed to the rail: this aspect in fact allows considerable simplification in production and assembly of switchboards in that upon variation in their dimensions or configurations it is possible to install bus bars of different length with the maximum ease. <IMAGE></p> |
