CR2 series intelligent motor soft starterDetailed product description：

The CR2 series intelligent motor soft starter is mainly suitable for controlling and protecting the starting, running, and stopping of squirrel cage motors. Because when the motor is directly started, the starting current can reach 7-10 times the rated current of the motor, which has a significant impact on the power grid and can affect the service life of mechanical equipment, even causing serious malfunctions and significant economic losses. The use of CR2 series intelligent motor soft starters can avoid these problems. In addition to the general functions of a regular soft starter, it also adds adjustable current function, intelligent monitoring and protection, communication function, etc., making the product more widely applicable to fields with high protection requirements and automation such as metallurgy, chemical industry, construction, mining, etc.
（1） The CR2 series intelligent motor soft starter has a soft start function, which can reduce the starting current and torque of the motor, and minimize the torque impact generated during starting;
（2） Equipped with soft parking function, it can gradually reduce the terminal voltage of the motor, avoiding damage to the equipment caused by sudden parking;
（3） It has protection function, which can protect against overload, underload, peak overcurrent, process overcurrent, phase failure, three-phase imbalance, locked rotor, radiator overheating, reverse sequence, current limiting starting timeout and other faults, and has PTC direct thermal protection and hourly starting frequency protection;
（4） It has programmable input and output functions, and can be set remotely/locally;
（5） Equipped with adjustable current setting function, achieving the purpose of matching the rated current of the motor and providing precise protection;
（6） Equipped with full Chinese LCD display function, it can display the main circuit current during operation and record 20 types of fault protection, and can set various parameters and protections;
（7） Can be equipped with communication function to achieve remote monitoring, etc.

The CR2 series intelligent motor soft starter complies with IEC60947-4-2 and GB14048.6 standards and has obtained the national mandatory product certification "CCC" mark
