EOCRSS-05S,EOCRSS-30S,EOCRSS-60S,EOCRSS-05W,EOCRSS-30W,EOCRSS-60W過(guo)電流(liu)保(bao)護繼(ji)電器又(you)稱過(guo)載保(bao)護器具有電流(liu)監(jian)測(ce) 。

EOCR-SS是超小型定時(shi)限(xian)動(dong)作特性的過(guo)電(dian)(dian)流繼電(dian)(dian)器。利用主回路相線(xian)穿過(guo)兩(liang)個互感(gan)器（CT）取得(de)電(dian)(dian)流感(gan)應信號。當負載異常時(shi)，經(jing)內部繼電(dian)(dian)器動(dong)作切斷控(kong)制回路電(dian)(dian)源，達到(dao)保(bao)護(hu)負載的目(mu)的。它具有(you)體積(ji)小、重量輕、抗(kang)干(gan)擾、無噪音 保(bao)護(hu)功(gong)能強、安(an)裝使用方(fang)便等(deng)優點。主要適(shi)用于電(dian)(dian)機、設備等(deng)的過(guo)載保(bao)護(hu)。EOCR-SS根據不同的控(kong)制電(dian)(dian)壓(ya)和保(bao)護(hu)電(dian)(dian)流范圍可分為EOCRSS-05S,EOCRSS-30S,EOCRSS-60S,EOCRSS-05W,EOCRSS-30W,EOCRSS-60W過(guo)電(dian)(dian)流保(bao)護(hu)繼電(dian)(dian)器又(you)稱過(guo)載保(bao)護(hu)器具有(you)電(dian)(dian)流監測保(bao)護(hu)、缺相和堵轉功(gong)能，相對于熱繼電(dian)(dian)器靈(ling)敏度快，精度高等(deng)特點。通過(guo)旋鈕(niu)調整還可以進行電(dian)(dian)流表的功(gong)能。
