Abstract
An arrangement used to fix conductor rails for multi-phase switchgears to allow for mounting and dismantling the conductor rails in a simple manner is provided. The switchgear housing (4) comprises straight guide elements (16) which are used to receive the mounting position using the conductor rails (8). Each conductor rail (8) includes a continuous bore (22) which is covered by a receiving bore (24) when in a mounted position, the receiving bore being formed in the switchgear housing (4). Insertion journals (28) extend through the continuous bores (22) into the receiving bores (24) associated therewith and are combined with a connecting web (30) in order to form an insertion comb (26) made of an insulating material.
