Switches series DS have been developed to the latest achievements in the field of switching devices through the application of quality insulation materials and contacts made with silver alloys. Modular construction allows subsequent changes, so stocking costs can be lowered. Elements that can be fixed to the left and/or right side of the switch: Because of the larger opening clearances the switches series DS are particularly suitable for main switches (switch disconnectors) and safety switches (emergency-off switches). Switches series DS are built in accordance with the following standards: IEC 60947-1,-3, IEC 60204, DIN EN 61058, 508,C22.2 No.14 etc. • Two modular frame sizes: A0 size (16-25-32-40 A) A1 size (40-63-80 A) • Mec hi protection degree - front part IP65, connection terminals IP20 (for switches CS40,63,80 - option with protection cover is required) • acts opening (IEC 60947-5-1 Annex K) • wed “self-lifting” clamps offer easier connection • rew mounting
