RCD ndi mawu omwe amagwiritsidwa ntchito m'malamulo ndi machitidwe, kuphatikiza RCCB, RCBO, ndi CBR. Ndiko kuti, zida zomwe zimapereka "chitetezo" chotsalira, ndiye kuti, mphamvu yotsalira ikadutsa malire omwe atchulidwa kapena chipangizocho chimazimitsidwa pamanja, amazindikira kuti otsalirawo ndi magetsi "amadzipatula" dera. Mosiyana ndi RCM (Residual Current Monitor) yomwe imagwiritsidwa ntchito "kuzindikira" zotsalira zapano koma sizipereka chitetezo chotsalira - onani zolemba za Article 411.1 ndi zomwe zalembedwa kumapeto kwa Article 722.531.3.101
RCCB, RCBO, ndi CBR zimapereka chitetezo popatula magetsi kuti apewe zolakwika zotsalira zomwe zimapangitsa kuti zida ziziyenda kapena kuzimitsa pamanja.
RCCB (EN6008-1) iyenera kugwiritsidwa ntchito limodzi ndi OLPD yosiyana, ndiko kuti, fuse ndi/kapena MCB ziyenera kugwiritsidwa ntchito kuteteza kuti isapitirire.
RCCB ndi RCBO ali ndi mawonekedwe okhazikika ndipo adapangidwa kuti azikhazikitsidwanso ndi anthu wamba pakagwa vuto.
CBR (EN60947-2) Chowotcha chozungulira chokhala ndi chitetezo chotsalira chapano, choyenera kugwiritsa ntchito apamwamba> 100A.
CBR ikhoza kukhala ndi mawonekedwe osinthika ndipo sichingakhazikitsidwenso ndi anthu wamba pakachitika cholakwika.
Ndime 722.531.3.101 imatchulanso EN62423; zofunikira zina zamapangidwe zomwe zimagwira ntchito ku RCCB, RCBO ndi CBR pozindikira F kapena B wotsalira wapano.
RDC-DD (IEC62955) imayimira chipangizo chotsalira cha DC chodziwikiratu *; mawu wamba pazida zingapo zopangidwira kuzindikira zolakwika zosalala za DC pakulipiritsa mapulogalamu mu Mode 3, ndikuthandizira kugwiritsa ntchito mtundu A kapena Mtundu F RCDs pozungulira.
RDC-DD muyezo IEC 62955 imatchula mitundu iwiri yoyambira, RDC-MD ndi RDC-PD. Kumvetsetsa mitundu yosiyanasiyana kumatsimikizira kuti simudzagula zinthu zomwe sizingagwiritsidwe ntchito.
RDC-PD (chipangizo choteteza) imaphatikiza 6 mA yosalala DC kuzindikira ndi 30 mA A kapena F chitetezo chotsalira chapano mu chipangizo chomwecho. Kulumikizana kwa RDC-PD kumakhala kwapadera pamagetsi pakachitika vuto lotsalira.
