特点多种电机保护功能内装MCU体现了过电流、缺相、不平衡、堵转、可逆等多种保护功能。可确认动作原因通过二级发光管或7-段显示窗可确认EMPR的动作原因，简化故障分析和处理。设置动作电流及时间根据负荷种类可设定电流和脱扣动作的时间，可适应各种负荷。NVR(不释放电压)功能EMPR的操作电源出现异常时，可直接切断过电流防止事故的发生。可选择反限时特性脱扣时间与过载电流成反比。过载电流越大，分断时间越短。LG(LS产电）热继电器GTH-22/3（0.1A0.16A0.25A0.4A0.63A1A2.5A4A5A6A7A9A12A16A19A)GTH-40/3(4A5A6A7A9A12A16A18A24A28A)GTH85/3(7A9A12A16A18A24A28A32A45A54A65A)GTH-100(34A39A43A54A65A85A)GTH-150(34A39A43A54A65A85A)GTH-150(34A39A43A54A65A85A100A)GTH-220(80A107A130A150A200A)GTH-400(107A130A150A200A250A350A)GTH-600(250A350A500A660A)交流接触器GMC-6GMC-9GMC-12GMC-18GMC-22GMC-32GMC-40GMC-50GMC-65GMC-75GMC-85GMC-100GMC-125GMC-150GMC-180GMC-220GMC-300GMC-400GMC-600GMC-800直流接触器GMD-9GMD-12GMD-18GMD-22GMD-32GMD-40GMD-50GMD-65GMD-75GMD-85四极接触器GMC-9/4GMC-12/4GMC-18/4GMC-22/4GMC-32/4GMC-40/4GMC-50/4GMC-65/4GMC-75/4GMC-85/4GMC-100/4GMC-125/4GMC-150/4GMC-180/4GMC-220/4GMC-300/4GMC-400/4GMC-600/4GMC-800/4GMD-9/4GMD-12/4GMD-18/4GMD-22/4GMD-32/4GMD-40/4GMD-50/4GMD-65/4GMD-75/4GMD-85/4交流接触器CJX2(D09-D620)系列)
