• 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, and power range from 5.5–55kW.
• ZJR2 series soft starter with built-in contactor provides perfect protection during motor starting and running.
• Adopted closed-loop control, greatly improving the stability of soft starting torque of the motor.
• There are 3 relays inside the soft starter — no need to add an external contactor.
• You have to inform the factory if you need a built-in contactor soft starter, because the factory standard soft starter is the economic type.
• ZJR2-B device type can work with three-phase AC motor in the process of starting too big acceleration torque.
• The power supply system provides protection from excessive current and dynamic impact.
• Has the following characteristics:

• 16 SCM control, intelligent II-digital display.

• Can be used as a soft starter to control multiple motors.

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

• Free stop and soft stop — the stop time from 0 to 60 seconds can be arbitrarily selected.

• Overcurrent, overload, open phase, instantaneous stop, and other fault protection, with flow, overloading, lack phase, instantaneous stop, and other malfunction protection.

• Easy installation, simple operation, strong function, and reasonable prices.
