Latching device for detachably latching switching apparatuses in their switched-on position

摘要

A latching device for electromagnetically operated switching apparatuses (1) has a roller lever (25) and a locking element (40) as well as an auxiliary magnet system for operating the roller lever (25), which is constructed as an armature. The locking element (40) is rigidly connected to a drive part (7), which supports the armature (6), of the magnetic drive of the switching apparatus (1). A supporting bracket of the latching device (20) is constructed to be rectangular and is matched to a corner of the housing (2) of the switching apparatus (1). The latching device can be inserted from the outside into the housing corner through an opening (51), and mounted there. The latching device can be joined to a switching apparatus as a module if the intention is that the switching apparatus be switched off and on relatively rarely. No excitation power is required for the magnetic drive in the period in which the switching apparatus is switched on. <IMAGE>
