Eaton DS7-340SX012N0-N Soft Starter, 12 A, 200-480 V AC, 5.5 kW, 3-Phase

Starting a three-phase motor directly on line causes high inrush currents and mechanical stress. The Eaton DS7-340SX012N0-N soft starter reduces that stress by ramping up voltage gradually, protecting both the motor and the connected machinery.

Who is it for

This soft starter is for industrial applications where smooth motor acceleration and deceleration are required, such as conveyor systems, pumps, fans, and compressors. It suits control panels and machine builders needing reliable motor starting with integrated protection.
