Soft Starter User Manual : Peaco Support soft starter user manual.pdf


  • This series soft starter comes with built-in contactor and provides 3 relays inside. There is no need to add external contactor.
  • The soft starter with built-in contactor can work with three phase AC motor and protect the motor from excessive current generated during the accelerating of large torque at starting of motor.
  • 16 SCM control and intelligent digital display are available with the motor soft starter.
  • High performance soft starter can control multiple motors.
  • Effective motor soft starter with starting modes: current limiting start, voltage ramp start, kick start +current-limiting start, kick start +voltage ramp start, current ramp start, voltage current-limiting double closed -loop start.
  • Reliable three phase soft starter features free stop and soft stop. The stop time can be selected freely from 0 to 60 seconds.
  • With full protection functions, overcurrent, overload, overheat, low voltage, high voltage, load short circuit, phase loss, phase loss, instantaneous stop, three-phase unbalance protections.
  • It is easy to install and simple to operate, featuring full and strong functions.
