Supporting rail for mounting and fixture of electrical switchgear

摘要

The rail (13) is mfd. of e.g. insulating GFRP and screwed (14, 15) firmly to the busbar adaptor (1), and has on its underside two guidance bars for lateral positioning on perforated mouldings (17, 18) whose holes (16) accept tapered pegs (24).To prevent displacement of the switchgear, tongues (15) are provided on top of the rail between supporting faces (20, 21) with roughened surfaces and a central rib (28). The tongues can be broken off if necessary and accommodate appts. of greater width.
