Small soft starter with integral bypass


ASTAT S is compact, easy to operate soft starter, designed for use with standard 3-phase squirrel cage motors. It provides an advanced method of reducing current during motor starting and stopping.


ASTAT S will start supplying a reduced voltage to the motor, increasing up to the rated voltage, so avoiding, high currents and generating soft starting and stopping. The motor has to be able to start in a reduced voltage.


  • Solid soft starter for standard 3ph AC motors up to 30kW at 400V AC
  • Voltage ratings up to 600V
  • Two phase control with integral bypass
  • Compact, small case
  • DIN rail mounting. Optional from 31A
  • Start and soft stop features
