ZJR2-B series soft starter with built-in contactor can work with three-phase ,AC squirrel cage induction asynchronous motor ,The voltage is 320V~460V, 50HZ/60HZ .Power range from 5.5-55kW .
ZJR2 series soft starter with built-in contactor 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 .
There have 3 relays inside the soft starter . No need to add external contactor .You have to inform the factory that you need built-in contactor soft starter .Because the factory standard soft starter is economic type.
ZJR2-B device type can work with three-phase AC motor in the process of starting too big acceleration torque, and power supply system plays a protection from excessive current harvest dynamic impact role, has the following characteristics:
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, over loading, lack phase, instantaneous stop, and other malfunction protection.
6. Easy installation, simple operation, strong function and reasonable prices.
