I-RCD yigama elijwayelekile elisetshenziswe emithethweni namakhodi wokuzilolonga, kufaka phakathi i-RCCB, i-rcbo, ne-cbr. Lokho wukuthi, amadivaysi anikezela "ngokuvikelwa" okusalayo kwamanje, okungukuthi, lapho okwenziwa khona okusele kudlula umkhawulo ochaziwe noma idivaysi icishiwe ngesandla, babona "ukuhlukanisa" umjikelezo. Ngokuphikisana ne-RCM (ukuqapha okusele kwamanje) okusetshenziselwa ukusetshenziselwa "ukuthola" okusele kwamanje kodwa akunikezi amanothi asabelo esisele - bona amanothi abhalwe phansi nge-Article 722.531.3.101
I-RCCB, i-RCBO, ne-CBBO ihlinzeka ngokuvikelwa kokuhlukanisa amandla okuthola amandla ukuvikela amaphutha asele akhona adala abangela ukuthi imishini idlule noma ivale ngesandla.
I-RCCB (EN6008-1) kumele isetshenziswe ngokuhlanganiswa ne-OLPD ehlukile, okungukuthi, i-fuse kanye / noma i-MCB kumele isetshenziselwe ukuyivikela kusuka ekutholeni ngokweqile.
I-RCCB ne-RCBO zinezici ezihleliwe futhi zenzelwe ukusethwa kabusha ngabantu abajwayelekile uma kwenzeka kuba nephutha.
CBR (EN60947-2) Breaker Wesekeli Enomsebenzi Wokuvikelwa Kwamanje Wakhelwe, Ofanele Izicelo Eziphezulu Zamanje> 100A.
I-CBR ingahle ibe nezimpawu eziguqukayo futhi ayinakusethwa kabusha ngabantu abajwayelekile uma kwenzeka kuba nephutha.
Isigaba 722.531.3.101 Futhi kubhekisele ku-EN62423; Izidingo ezengeziwe zokuqamba ezisetshenziswa ku-RCCB, i-RCBO ne-CBR yokuthola i-F noma B Insary yamanje.
I-RDC-DD (IEC62955) imele insiza ye-DC yamanje yokuthola i-DC *; Igama elijwayelekile lochungechunge lwemishini eyenzelwe ukuthola iphutha elibushelelezi le-DC yamanje ekushaja izinhlelo kumodi 3, futhi isekela ukusetshenziswa kohlobo lwe-Type A noma uhlobo lwe-F CCD.
I-RDC-DD ejwayelekile IEC 62955 icacisa amafomethi amabili ayisisekelo, i-RDC-MD ne-RDC-PD. Ukuqonda amafomethi ahlukile kuzoqinisekisa ukuthi ngeke uthenge imikhiqizo engeke isetshenziswe.
I-RDC-PD (idivaysi evikelayo) ihlanganisa ukutholwa kwe-DC e-DC e-6 Ukuxhumana kwe-RDC-PD kuhlukaniswe ngogesi uma kwenzeka kunephutha lamanje elisele.
