What this 1150 A motor choke does on the line
Schneider VW3A68554 is a motor choke rated 1150 A for 400/500 V systems — sized for the output of a large Altivar drive feeding a high-current motor, pump, or conveyor. The choke smooths voltage reflections and limits dV/dt at the motor terminals, which keeps winding insulation stress in check on long cable runs. On a body-shop weld line or a heavy conveyor, that 1150 A rating holds takt time by preventing nuisance overvoltage trips that stop the process.
