I-RCD ligama eliqhelekileyo elisetyenziswa kwimigaqo kunye neekhowudi zokusebenza, kuquka i-RCCB, i-RCBO, kunye ne-CBR. Oko kukuthi, izixhobo ezibonelela "ngokhuseleko" lwamandla asele, oko kukuthi, xa amandla asele edlula umda ochaziweyo okanye isixhobo sicinywe ngesandla, zifumanisa amandla asele kwaye "zihlukanise" isekethe ngombane. Ngokuchasene ne-RCM (Residual Current Monitor) esetyenziselwa "ukufumanisa" amandla asele eseleyo kodwa engaboneleli ngokhuseleko lwamandla asele eseleyo-jonga amanqaku kwiNqaku 411.1 kunye nemigangatho yemveliso edweliswe ekupheleni kweNqaku 722.531.3.101
I-RCCB, i-RCBO, kunye ne-CBR zibonelela ngokhuseleko ngokwahlula umbane ukuze kuthintelwe iimpazamo zamandla eziseleyo ezibangela ukuba izixhobo zikhubeke okanye zicime ngesandla.
I-RCCB (EN6008-1) mayisetyenziswe kunye ne-OLPD eyahlukileyo, oko kukuthi, i-fuse kunye/okanye i-MCB mayisetyenziswe ukuyikhusela kwi-overcurrent.
I-RCCB kunye ne-RCBO zineempawu ezizinzileyo kwaye zenzelwe ukuba zisetwe ngokutsha ngabantu abaqhelekileyo xa kukho impazamo.
I-CBR (EN60947-2) I-circuit breaker enomsebenzi wokukhusela umsinga osele owakhelwe ngaphakathi, ifanelekile kwii-current current eziphezulu >100A.
I-CBR isenokuba neempawu ezihlengahlengiswayo kwaye ayinakusetwa kwakhona ngabantu abaqhelekileyo xa kukho impazamo.
Inqaku 722.531.3.101 likwabhekisa kwi-EN62423; iimfuno ezongezelelweyo zoyilo ezisebenza kwi-RCCB, i-RCBO kunye ne-CBR zokufumanisa umsinga osele we-F okanye i-B.
I-RDC-DD (IEC62955) imele isixhobo sokufumanisa umbane esisele sisele*; igama eliqhelekileyo loluhlu lwezixhobo ezenzelwe ukubona umbane wempazamo ye-DC egudileyo kwizicelo zokutshaja kwiMode 3, kwaye ixhasa ukusetyenziswa kwee-Type A okanye ii-Type F RCDs kwisekethe.
Umgangatho we-RDC-DD i-IEC 62955 uchaza iindlela ezimbini ezisisiseko, i-RDC-MD kunye ne-RDC-PD. Ukuqonda iindlela ezahlukeneyo kuya kuqinisekisa ukuba awuyi kuthenga iimveliso ezingasetyenziswayo.
I-RDC-PD (isixhobo sokukhusela) idibanisa i-6 mA egudileyo yokufumanisa i-DC kunye nokhuseleko lwamandla aseleyo angama-30 mA A okanye F kwisixhobo esinye. Unxibelelwano lwe-RDC-PD lususwa ngombane xa kukho ingxaki yamandla aseleyo.
