Mounting device for isolators, lower parts and the like

摘要

A mounting device for fitting the framework (1) of low-voltage high rupture capacity safety isolators on supporting rails (5) which are fitted in a fixed position at a distance from one another and have a top-hat section profile, fastening hooks (6) having a suspension tab (7), which extends at right angles to the bearing plane of the framework (1), and clamping pieces (8) which can be displaced alongside being arranged in the lower region of the framework (1). In order that a defined level (L) of the framework (1) can be maintained at the same height, even using simple fitting means, with a different separation of the supporting rails (5), it is provided according to the invention that the fastening hook (6) has at least two suspension tabs (7) which are arranged at a predetermined spacing (f) one above the other. <IMAGE>
