Product Center
FTR-K series high-energy motor soft starter is customized according to user requirements and can meet the requirements of special environments and occasions such as high altitude, high temperature, low temperature, high humidity, marine salt spray, and vehicle-mounted. It has a wide range of voltage and capacity coverage. It is mainly used for the control of three-phase AC 50/60Hz ±5%, rated voltage 220V-1140V, and rated power 7.5kW-1000kW AC asynchronous motors. This product adopts reliable 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 and contactor to meet the motor control requirements.
