I-RCD ligama eliqhelekileyo elisetyenziswa kwimimiselo kunye neekhowudi zokwenza, kubandakanywa i-RCCB, i-RCBO, kunye ne-CBR. Okokuthi, izixhobo ezibonelela ngoku "ukukhusela" okushiyekileyo, oko kukuthi, xa i-residual current idlula umda ochaziweyo okanye isixhobo sicinywe ngesandla, sibona i-residual current kunye nombane "zihlukanise" isiphaluka. Ngokuchasene ne-RCM (i-Residual Current Monitor) esetyenziselwa "ukubona" ​​i-residual current kodwa ayiboneleli ngokukhuselekileyo ngokukhuselekileyo-jonga amanqaku kwiSiqendu 411.1 kunye nemigangatho yemveliso edweliswe ekupheleni kweSiqendu 722.531.3.101
I-RCCB, i-RCBO, kunye ne-CBR zibonelela ngokhuseleko ngokuhlukanisa unikezelo lwamandla ukuthintela iimpazamo zangoku ezishiyekileyo ezibangela ukuba isixhobo sihambe okanye sivale ngesandla.
I-RCCB (EN6008-1) kufuneka isetyenziswe ngokudibanisa ne-OLPD eyahlukileyo, oko kukuthi, i-fuse kunye / okanye i-MCB kufuneka isetyenziswe ukuyikhusela kwi-overcurrent.
I-RCCB kunye ne-RCBO zineempawu ezisisigxina kwaye zenzelwe ukusetwa kwakhona ngabantu abaqhelekileyo xa kukho impazamo.
I-CBR (EN60947-2) I-CBR (EN60947-2) I-Circuit breaker enomsebenzi wokukhusela okhoyo owakhiweyo, ofanelekileyo kwizicelo eziphezulu zangoku> 100A.
I-CBR inokuba neempawu ezilungelelanisiweyo kwaye ayinakusetwa ngokutsha ngabantu abaqhelekileyo xa kukho impazamo.
Inqaku 722.531.3.101 likwabhekisela kwi-EN62423; Iimfuno zoyilo ezongezelelweyo ezisebenzayo kwi-RCCB, RCBO kunye ne-CBR zokubona i-F okanye i-B eshiyekileyo yangoku.
I-RDC-DD (IEC62955) imele isixhobo sokufumanisa i-DC yangoku*; ixesha eliqhelekileyo kuthotho lwezixhobo ezenzelwe ukukhangela i-DC egudileyo ekhoyo ngoku kutshaja izicelo kwiMowudi 3, kwaye ixhasa ukusetyenziswa kohlobo A okanye uhlobo lwe-RCDs kwisekethe.
Umgangatho we-RDC-DD we-IEC 62955 ukhankanya iifomati ezimbini ezisisiseko, i-RDC-MD kunye ne-RDC-PD. Ukuqonda iifomathi ezahlukeneyo kuya kuqinisekisa ukuba awuyi kuthenga iimveliso ezingenakusetyenziswa.
I-RDC-PD (isixhobo sokukhusela) idibanisa i-6 mA i-smooth DC yokufunyanwa kunye ne-30 mA A okanye i-F yokukhusela ngoku okuseleyo kwisixhobo esifanayo. Uqhagamshelwano lwe-RDC-PD lubekwe lodwa ngombane xa kukho impazamo yangoku eseleyo.
