ZJR2 Series Soft Starter With Built-in Contactor

ZJR2-B Series Soft Starter with built-in contactor

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.

Demonstration of the Model

Scope of application for ZJR2 Soft Starter:

ZJR2-B series soft starter motor applies to centrifuges, blower, compressor, transport planes, mixer, rolling ball mill broken machines and mechanical equipment motor starter.
