They are usually applied for switch disconnectors and circuit breakers medium and high voltage. There are two versions: s OPEN DESIGN PROTECTION DEGREE )0 TYPE DESIGNATION SN s WITH PROTECTIVE SHEET METAL LID )0 PROTECTION TYPE designation SNL . Signal switches consist of a number of switching elements which are made from high quality insulation materials and contacts made with silver alloy highly resistant to electric arc. This ensures a high breaking capacity and high mechanical and electrical durability. Working stroke of the switch is 90°, started 45° in relation to the CENTERLINE SEE DIMENSIONAL DRAWING IN THE DIRECTION OF CLOCKWISE 9OU CAN ADJUST THE DESIRED ANGLE WITHIN THE RANGE OF ¨ WITH THE REGULATION CAMS TO ¨ ACCURACY OF ± ¨ FOR EACH SWITCHING element separately.
