Schneider Electric ATS430C32S6 Altivar ATS430 320A 208-600V 160kW Soft Starter

The Schneider Electric ATS430C32S6 is a 3-phase Altivar Soft Starter ATS430 rated for 320A continuous operation on a 208-600V AC supply. It drives asynchronous motors up to 220kW depending on line voltage, using torque control with 99.5% efficiency and an internal bypass to limit heat dissipation once the motor is running at speed.

Selection Notes

The 320A rating sizes the ATS430C32S6 for motors from 90kW at 230V up to 220kW at 500-525V, so match the drive to the actual line voltage rather than the current figure alone. The 400% Ie for 13s overload rating and internal bypass keep dissipation low once the motor reaches full speed, which matters most on frequent-cycling loads such as pumps, fans, compressors, conveyors, and mixers. Pick the next size up in the ATS430 range when the driven load's starting torque or duty cycle exceeds the 320A frame's 13-second overload window; pick the size below it when the motor's full-load current sits well under 320A, since an oversized starter loses current-limiting resolution.
