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 . 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.
ZJR2 Series Soft Starter 7.5KW
Main Features for ZJR2 series soft starter:
ZJR2 device type can work without 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 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;
7.The 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 .
