Additional fasteners are then either not at all or only needed in a simplified form. If screws are used, they can be screwed into a nut thread intervene in a known manner by means of an insulating material metallic insert nut or press nut on the wall is formed (DE 35 39 673 A1).

  • connection rails the current carrying capacity by means of the wall thickness the hollow rail regulates the conductive, current carrying Cross section forms. It follows that at lower Current strengths due to small wall thicknesses a larger one, respectively at higher currents through thicker walls a smaller internal cavity is present, which is down to a massive design with no void, at the highest Rated current.

Abstract

L'invention concerne des profilés de raccordement (1; 4; 7; 13; 31; 43) d'appareils et de dispositifs électriques destinés à différents courants nominaux. Ces profilés sont de conception creuse et peuvent présenter une seule ou plusieurs cavité(s) (2; 5; 8; 18-20; 24-26; 32). Les profilés de raccordement (1; 4; 7; 13; 31; 43) ont la même section externe pour toutes les intensités de courant mais ils ont des parois d'épaisseurs différentes pour les différentes intensités et donc des cavités de différentes tailles (2; 5; 8; 18-20; 24-26; 32). Ainsi, les passages des profilés de raccordement des boîtes de commutation concernées d'une série type peuvent tous être identiques, correspondant aux dimensions des profilés de raccordement de l'intensité maximale.
