Schneider Electric ATS430C41S6 Altivar ATS430 410A 208-600V 220kW Soft Starter

The Schneider Electric ATS430C41S6 is a 3-phase Altivar Soft Starter ATS430 rated for 410A continuous operation on a 208-600V AC supply. It drives asynchronous motors up to 250kW 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 410A rating sizes the ATS430C41S6 for motors from 110kW at 230V up to 250kW 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 410A frame's 13-second overload window; pick the size below it when the motor's full-load current sits well under 410A, since an oversized starter loses current-limiting resolution.
