Marine lifting motor NJR2-D series soft starter is based on advanced dual CPU control technology, controls thyristor module, realizes soft start and soft stop function of (squirrel cage) three-phase asynchronous motor, and has overload , input phase loss, output phase loss, load short circuit, start current limit timeout, over voltage, under voltage and many other protection functions. This product is mainly used in conjunction with the complete control cabinet. In use, the AC contactor for bypass of the corresponding specification must be matched. The product specifications cover 7.5kW~500kW (squirrel cage) three-phase AC asynchronous motor, which is widely used in metallurgy, fire protection, mining, water supply, municipal, food, cement, petrochemical and other fields. It is a traditional star--triangle The most ideal replacement product for starting and self-driving step-down.

　　Meet the standard: GB 14048.6 IEC 60947-4-2.

　　Technical parameters and performance
