成套软启动控制柜是以软起动器为控制主体，并配以相应规格的接触器组装成控制柜，实现三相交流鼠笼式异步电动机的软起动、软停止功能，同时具有过载、过流、缺相、三相不平衡、过压、欠压等多项保护功能。广泛应用于冶金、石油、化工、机械、供水、市政、水泥、等行业，是传统Y/△起动、自耦降压起动等理想的替换产品。

The complete set of soft start control cabinet is composed of a soft starter as the main control body and corresponding specifications of contactors to achieve the soft start and soft stop functions of three-phase AC squirrel cage asynchronous motor. It also has multiple protection functions such as overload, overcurrent, phase loss, three-phase imbalance, overvoltage, undervoltage, etc. Widely used in industries such as metallurgy, petroleum, chemical industry, machinery, water supply, municipal engineering, cement, etc., it is an ideal replacement product for traditional Y/△ starting, self coupling voltage reduction starting, and other industries.

成套软启动控制柜主要降低电动机的起动电流，减小配电容量，避免增容投资，减小起动应力，延长电动机及相关设备的使用寿命。具有多种起动模式和宽范围的电流、电压等设定，可适应多种负载情况。配有主回路进线断路器，旁路接触器于一体，用于实现电动机的多重控制保护。同时还有起动、停止按钮及运行、停止、故障指示和预留远控接点。远控接点有起停输入接点，运行输出接点，故障输出接点（均为无源继电器接点），计算机通讯接口供上位机控制和管理之用。

The complete set of soft start control cabinet mainly reduces the starting current of the motor, reduces the distribution capacity, avoids capacity increase investment, reduces starting stress, and extends the service life of the motor and related equipment. It has multiple starting modes and a wide range of current, voltage, and other settings, which can adapt to various load conditions. Equipped with a main circuit breaker and a bypass contactor, it is used to achieve multiple control and protection of the motor. At the same time, there are start and stop buttons, operation, stop, fault indication, and reserved remote control contacts. Remote control contacts include start stop input contacts, operation output contacts, fault output contacts (all passive relay contacts), and computer communication interfaces for upper computer control and management.
