Product Description

ST200 Online Soft Starter 3phase 380V For Motor Not By Pass Contactor


ST200 online soft starter overview


ST200 motor soft starter is a new type motor starting and protection device that is integrated with power electronic technology, microprocessor and automatic control. 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.
No need to built by pass contactor with SCR controlling new technology applying----innovation and cost saving.


Multiple motor protection functions


Phase missing protection


Over heat protection


Over current and over load protection


Output unbalance protection


Under voltage and over voltage protection


Load circuit protection


Under load protection
