Wholesale soft starter with bypass contactor electric soft start motor starter for chemical factory

Wholesale soft starter with bypass contactor, electric soft start motor starter for chemical factory

1. ZJR2 series soft starter can work with three-phase, AC squirrel cage induction asynchronous motor, The voltage is 320V~460V, 50HZ/60HZ and the current is 1200A and below .

2. ZJR2 series soft starter are in the process of motor starting and running a perfect protection function, adopted the closed loop control, greatly improving the stationarity of soft starting torque of the motor.

3. The soft starter is a device type .It’s necessary to add breakers (short-circuit protection ) and AC contactor (Bypass) inside the cabinet . together with switches are made up of electric motor control circuit .

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 choosed .

5. Over current , Overload , Open phase, instantaneous stop and other fault protection .

with the flow, over loading, lack phase, instantaneous stop, and other malfunction protection;

6. Easy installation, simple operation, strong function and reasonable prices;
