Apparatus for covering electrical equipment attached to busbars

Apparatus for covering electrical equipment connected to a plurality of aligned busbars of a bus system and having a maximum structural height, and wherein the upper sides of the busbars are equidistantly spaced from the clamping faces of holders for receiving and retaining the busbars, characterized in that:

• said apparatus is in the form of a cap (10) having a rectangular cross section and comprising a cover plate (11) and two pairs of side walls (18, 19);
• a pair of first side walls (19) extends parallel to said busbars (33, 34, 35) and has an internal height with respect to said cover plate (11) which corresponds to at least the sum of a fastening distance (h) between the upper sides of said busbars and said clamping face and said structural height (H);
• a pair of second side walls (18) projects past the outermost busbars of said bus system and is provided with cutouts (48) at the side facing away from said cover plate (11), the depth of said cutouts (48) directed perpendicular to said cover plate (11) and corresponding to said fastening distance (h);
• at least one holding clamp (40) is attachable to the inner side of said cover plate (11) for interaction with at least one of said busbars (33, 34, 35), said holding clamp (40) having a clamping leg (42) extending across said busbar and abutting it in the rear thereof;
• and said cutouts (48) extend in a plane parallel to said cover plate (11) and are of a dimension which corresponds to a length (a)+(b) measured from outermost to outermost end of the outermost busbars, plus an adjustment length (c) which corresponds to at least an abutment length (f) of said clamping leg (42) of said holding clamp to one of said busbars.
