Motor soft starter 4 - 2000 kW | LEKTROMIK® S; SD2 series

Mechanical ¨ Reduced costs of transmission components - Low starting torque - Starting torque adjustable to requirement ¨ Reduced maintenance costs - Low starting torque reduces belt slip ¨ Lower repair costs - Fatigue effects reduced (Star/delta, transformer and single-phase starting cause high torque peaks) ¨ Machine protection - Electronic overload trip (with OPTION I1) Electrical ¨ Low starting current - Advantageous compared with star/delta ¨ Low maintenance costs - Low-loading of contactor contacts with zero-current switching ¨ Only two voltage ranges - 3AC 110...500 ±10 % V - 3AC 220...690 ±10 % V
