用途和适用领域 Application and applicable field

用户根据需要选配功能模块或附件，即可实现对各类电动机负载、配合负载的控制与保护。

控制保护开关，主要用于交流50Hz(60)、额定电压低于690V。工作电流小于125A以下的电力系统中接通、承载和分断正常条件下包括规定的过载条件下的电流，且能够接通承载并分断规定的非正常条件下的电流、过流、欠流、堵载、漏电、三相不平衡、过压、欠压。

控制保护开关外形精致，智能化功能强大，电流脱扣整定精确，安装使用方便，特别适用于现代化建筑中的水泵、风机、空调、消防照明等电控系统;冶金、煤矿、石化、港口、船舶、铁路、纺织等领域的电动机控制和保护，电动机控制中心(MCC)尤其是智能化电控系统或高分断能力的MCC(要求ICS达到12KA的配电控制系统);工厂或车间的单电机控制与保护，以及远程控制照明系统中。

According to the needs of users to select functional modules or accessories, can achieve al kinds of motor load, matching loadcontrol and protection.

Control and protection switch, mainly used for Ac 50Hz (60), rated votage less than 690v. in the power system with workingcurrent less than 125A, the normal condition includes the specified overload current, and can turn on and break the current.overcurrent, undercurent, blocking load, leakage, three-phase imbalance, overvoltage and undervoltage under the specifiedabnormalconditions.

The control and protection switch is exquisite in shape, powerful in inteligent function, accurate in current trio settingconvenient in installation and use, especially suitable for pump, fan, air conditioning, fire lighting and other electronic controsystems in modern buildings. Motor control and protection in metallurgy, coal mine, petrochemical, port, ship, railway, textile andother fields, motor control center (Mcc), especialy inteligent electronic control system or MCC with high breaking capacity(distribution control system requiring IcS to reach 12KA), single motor control and protection in factory or workshop, and remotecontrol lighting system.
