适用范围 Applicable scope

       SW11型三相交流保护继电器，具有阻容降压、体积小、重量轻等优点，它能对三相电源错相、缺相、断相能正确检测保护，使电机立即停运，红色指示灯亮（在有感性负载的情况下），黄色指示灯灭，排除故障后，自行复位，黄色指示灯亮，红色指示灯灭，（恢复至正常状态）。对于电机启动瞬间或其他原因所致的电网波动，CM-PAS型三相交流保护继电器有较强的适应能力，因而系统正常工作。

       SW11 three-phase ac protection relay has the advantages of resistance to pressure, low volume, light weight and so on.Phase and phase fault can be correctly detected to protect the motor immediately, red indicator light (in case of inductive load), yellow indicator light.Extinguish, after troubleshooting, self-reset, yellow indicator light, red indicator light out, (return to normal state). For motor startup moment.The CM-PAS three-phase ac protection relay has a strong adaptability, and thus ensures the normal operation of the system.
