ZJR2 Series motor soft starter is suitable for three phase. AC squirrel cage induction asynchronous motor, voltage is 320V~ 460V 50(60)Hz. Rated current is 1200A and below. Add breakers (short circuit protection) and AC contactor (Bypass) inside the cabinet, together with switch-gear makes up the electric motor control circuit. Thermal relay not required, there have perfect motor protection function while the motor start and running, adapt closed-loop control, improve motor’s stationary and reliability of soft torque start/soft and torque stop. Use Bypass contactor when running. The running power is almost zero. Drastically improve the reliability of the soft starter and reduce the overall size.
