Product Overview:

The 3 phase 660V SJR3-3000 series online micro-power consumption motor soft starter of Zhejiang Saikong. It expands new functions such as literal display, industrial communication and various protections based on the products of SJR2 series motor soft starter. The company has made further technical improvement in both the software and the structure of the soft starter according to the market demand. With inbuilt bypass contactor the soft starter provides complete motor protection functions including start control, running and overloading, phase failure, three-phase unbalance, over-voltage, under-voltage protection and so on with no need to further install bypass contactor and thermal relay, therefore, as another great achievement in the intelligentization of motor protection and networked technology application, it simplifies the circuit, reduces the volume, cuts the cost, makes installation and using more convenient.
