ST210-GC3 Soft Starter with bypass contactor 

ST210-GC3 motor soft starter is a new type motor starting and protection device that is integrated with power electronic technology, microprocessor and automatic control, but we built by pass contactor inside. 
This soft starter built in bypass contact inside for end user easy installation and easy using.
We can select  by pass contactoer brand as customer required.
This soft starter is able to steadily start and stop motor without step change so as to avoid mechanical or electric impact resulted from using conventional starting modes such as direct starting, star-delta starting and auto voltage reducing starting, and effectively reduce starting current and distribution capacity for fear of more investment on capacity expansion.
