Abstract

A barrier system for a line leadthrough in an electric installation has mutually adjacent wall elements forming barriers that extend in an axial longitudinal direction and are spaced apart from each other, forming channels. The wall elements lie partially on a support, at least at their lower ends. The wall elements are joined by a plug element to the leadthrough. Slots having a width which corresponds to the wall thickness of the wall elements are arranged in the plug element. The wall elements can be inserted into the slots, thus permitting a barrier system to be quickly and easily assembled and disassembled.
