The ZBR5 series intelligent motor soft starter is suitable for three-phase AC squirrel cage asynchronous motors with AC 380V, 660V, 50Hz/60Hz, rated current of 1200A and below. The soft starter adopts intelligent digital control, with a microcontroller as the intelligent center and a thyristor module as the executing element for fully automatic control of the motor. It is suitable for starting squirrel cage asynchronous motors with various loads, enabling the motor to start smoothly under any working conditions, protecting the driving system, reducing the impact of starting current on the power grid, and ensuring reliable starting of the motor; Smooth deceleration and parking to eliminate the anti inertia impact of the drag system. Complete system protection functions extend the service life of the system, reduce system costs, and improve system reliability. Compatible with various functions of all starting devices, it is the most ideal upgraded product for traditional star, delta starting, autotransformer voltage reduction starting, magnetic control voltage reduction starting, and more.

This product also has the following protective functions:

Motor phase failure alarm and stop;

Electric motor overcurrent or overload, alarm first and then stop;

Alarm or stop if the input voltage exceeds the limit;

If the starting time is too long (too many times), it will cause the radiator to overheat, and the soft starter will alarm or stop;

Built in electronic quick break protection, which can automatically protect and trigger an alarm in case of a short circuit fault during operation.

Main technical parameters:

Soft start time: 2 seconds~60 seconds (adjustable)

Soft shutdown time: 0-60 seconds (adjustable)

Soft start starting starting voltage: （30%~70%）Un

Soft start current limit range: （50%~500%）In
