Product details

Function and Usage

The NJR2-G series soft starter control cabinet is composed of a soft starter as the main control unit and corresponding contactors, realizing the soft start and soft stop functions of three-phase AC squirrel cage induction motors. It also has multiple protection functions such as overload, overcurrent, phase loss, three-phase imbalance, overvoltage, and undervoltage. It is widely applied in metallurgy, petroleum, chemical industry, machinery, water supply, municipal, cement, and other industries, and is an ideal replacement for traditional Y/△ starting and autotransformer voltage reduction starting.
