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 rated current 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 By-pass contactor when running. The running power is almost zero. It can improve the reliability of the soft starter and reduce the overall size.

1.16 SCM control, intelligent all-digital display.

2.Can be put into practice a soft starter control multiple motors.

3.Starting modes: Current limiting starter. Voltage ramp start, Kick start +current-limiting start, Kick start +voltage ramp start. Current ramp start. Voltage current-limiting double closed-loop start.

4.Free stop and soft stop. The stop time from 0 to 60 seconds can be arbitrary selected .

5.Over current. Overload. Open phase, instantaneous stop and other fault protection, with the flow, lack phase, instantaneous stop, and other malfunction protection.

6.Easy installation, simple operation, strong function and reasonable price.

7.5.5kW-55kW soft starter also have built-in bypass contactor. But the factory default is not with built-in bypass contactor. Clients need to confirm this once order confirmed.
