適用范圍 Applicable scope

       SW11型三相交流保護(hù)繼電器，具有阻容降壓、體積小、重量輕等優(yōu)點(diǎn)，它能對(duì)三相電源錯(cuò)相、缺相、斷相能正確檢測(cè)保護(hù)，使電機(jī)立即停運(yùn)，紅色指示燈亮（在有感性負(fù)載的情況下），黃色指示燈滅，排除故障后，自行復(fù)位，黃色指示燈亮，紅色指示燈滅，（恢復(fù)至正常狀態(tài)）。對(duì)于電機(jī)啟動(dòng)瞬間或其他原因所致的電網(wǎng)波動(dòng)，CM-PAS型三相交流保護(hù)繼電器有較強(qiáng)的適應(yīng)能力，因而確保系統(tǒng)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.
