<p>The safety electrical switch with fuse cut-out (4) excels by the fact that the insertion of the fusible cut-out is possible in a quick and easy manner, however only after moving the protective cover (3) into the open position, while inside the switch the electric circuit is disconnected. The access to the inside of the enclosure and in particular of the fusible cut-out as well as other electrically conductive parts is also physically enabled only after the electrical circuit through the switch is interrupted. The switch includes an enclosure (1) inside of which there is a bracket (2) of the fusible cut-out (4) inserted around the rotating point (20), where a protective enclosure (3) is rotationally attached to the rotating point (30). During the shifting of the enclosure (3) into the open position the electrical circuit inside the enclosure (8) is disconnected via the slotted lever (33) in the area of the disconnector (17). It is only after that it is possible to turn the bracket (2) with fusible cut-out (4) around the rotating point (20).</p> |
