电子式电动机保护器已由晶体管发展到集成电路至今已发展到微处理芯片厚模电路，从功能上一般分为断相保护、综合保护（多功能保护）、温度保护和智能保护。此类保护器具有节能、动作灵敏、度高、耐冲击振动，重复性好、保护功能齐全、功耗小等优点。
1.电动机保护器（电机保护器）是以检测线电流的变化（包括采取、正序、负序、零序和过流）为原则，可检测断相或过载信号。除具有断相保护功能外，还具有过负荷、堵转保护功能。
2.智能保护：集保护、遥测、通讯、遥控与一体的电动机保护装置，对电动机发生断相、过载、短路、欠压、过压和漏电等故障时实现保护，还具有电流电压显示，时间控制，软件自诊断，来电自恢复，自启动顺序，故障记忆，自琐和远传报警，显示故障时的电流、电压故障前后用代号闪烁示警，配置RS485通讯接口，实现计算机联网。同时可监控、监测256台电动机工作等功能。
