CHZIRI Soft Starter:
ZJR2 Series motor soft starter, is suitable for three phase , AC squirrel cage induction asynchronous motor, the voltage is 320V 460V. 50(60)Hz, The rate d curr ent is 1200A and below.The soft starter is assembled type .need to add breakers (short-circuit protection )and AC contactor ( Bypass ) inside the cabinet . together with switches are made up of electric motor control circuit .
It s no need to install the thermal relay . there have perfect motor protection function while the motor start and running . adapt closed-loop control,improve the stationarity and reliability of the motor 's soft torque start and soft torque stop . Use pass-by contactor when running .The running power is almost zero. It can improve the reliability of the soft starter and reduce the overall size.
