Product Overview:
The 3 phase 380V 37kW SJR3-3000 series online micro-power consumption motor soft starter of Zhejiang Saikong. 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.
Product Features:
◎ It support a variety of communication protocols; operation panel can be used outside; programmable output: 4-20MA DC analog output
◎ Compared to intense heating, heavy harmonic pollution and high module, consumption caused by online module, this type of soft starter has a longer using life and more safety
◎ The display is more intuitive and convenient.
◎ It greatly slashes the material cost
◎ Compared with star-delta starter and self coupling decompression starter, greatly cut down the design and installation time for no need of deploying line circuitry.
