              DS600 series intelligent motor protector

              ProductOverview

              The products are our new generation of intelligent motor protection controller. The product cooperates with contactor, soft starter, and moulded case circuit breaker to offer a set of specialized solution integrating control, protection, monitoring and bus communication for the LV AC motor circuit. It replace the thermal relay, thermal protector, leakage protector, under-voltage protector and other protection devices, and eliminates the time relay, intermediate relay, auxiliary relay, current transformer, instrumentation, control and selector switch, programmable logic controller, transmitter and other add-on components, thereby rendering an ideal option for intelligent MCC. The device is suitable for AC induction motors with AC 50Hz, rated voltage AC380V/660V, and rated current of below 800A.
