1.*工厂预制的电机起动器适于开关、保护任何三相负载 

2.具有直接起动器、可逆起动器或软起动器（只限于高性能起动器）三种类型

 1.标准电机起动器内置的断路器和接触器，单机zui大保护功率至  5.5kW 

2.高性能电机起动器内置电机保护型断路器、固态过载机电电器和接  触器或软起动器，单机zui大保护功率至 7.5kW 

3.自组装的 40 / 50A 动力小母线，也就是说每个电机起动器组只需  连接一根动力进线电缆 

4.支持热（带电）插拔功能 

5. 集成用于闭锁和显示所需的输入输出

 6.集成对于开关、保护功能的主动诊断功能

 7.电机起动机能够与其他扩展模板相组合：如， 制动控制模板就是  用于感应式电动机的机电制动装置的控制。不仅如此，它还配备了 额外的两个输入端子用于实现特殊功能（对于标准电机起动器的快 速停车，以及对高性能电机起动器特殊功能的参数化）

 8. 集成安全技术（有关内容参见 ET 200S 安全型电机起动器 – 就地 /   PROFIsafe，*欧洲安全技术规范（EN 954 - 1） 的要求。
