Device for locking at least one modular electric apparatus on a mounting rail, and electric switchgear apparatus fixed onto the rail by means of one such device

摘要

The mechanism has bolts (32, 33) comprising a moving part slidable with respect to an enclosure of a modular apparatus. The moving part comprises an end part that cooperates with a longitudinal edge of a rail and another end part, which is operated by a user to move the bolts between two positions. An operation part (19) of the bolts is provided with an extension device (P). The extension device comprises an end part (12) that is fixable on the operation part and another end part (13), which comprises an operation unit (20) that is actuatable by the user to actuate the bolts. An independent claim is also included for an assembly of modular electrical apparatuses to be mounted on a rail assembly.
