FTR-T series motor soft starter integrates the bypass contactor inside the product, simplifying the cumbersome process of user wiring. It is mainly used for the control of three-phase AC 50/60Hz ±5%, rated voltage 380V-690V, and rated power 8kW-400kW AC asynchronous motors. This product adopts motor control technology and integrates functions such as motor starting, data acquisition and display, motor protection, and soft stopping into one. The simple Chinese and English liquid crystal display interface makes operation simpler and quicker. Users only need to connect an external molded case circuit breaker to meet the motor control requirements.
