RCD izwi rinoshandiswa mumitemo nemirairo yekushanda, kusanganisira RCCB, RCBO, uye CBR. Kureva kuti, zvishandiso zvinopa "dziviriro" yemagetsi akasara, ndiko kuti, kana magetsi asara akadarika chiyero chakatarwa kana mudziyo ukadzima nemaoko, zvinoona magetsi asara uye zvino "paradzanisa" circuit nemagetsi. Kusiyana neRCM (Residual Current Monitor) iyo inoshandiswa "kuona" magetsi asara asi isingape dziviriro yemagetsi akasara - ona zvinyorwa zveChinyorwa 411.1 uye zviyero zvechigadzirwa zvakanyorwa pakupera kweChinyorwa 722.531.3.101.
RCCB, RCBO, uye CBR zvinopa dziviriro nekuparadzanisa magetsi kuti zvidzivirire zvikanganiso zvemagetsi zvinosara zvinokonzera kuti michina igumburwe kana kuvharwa nemaoko.
RCCB (EN6008-1) inofanira kushandiswa pamwe chete neOLPD yakasiyana, kureva kuti, fuse uye/kana MCB zvinofanira kushandiswa kuidzivirira kubva pakupfupfuta kwemhepo.
RCCB neRCBO dzine hunhu hwakasimba uye dzakagadzirirwa kugadziriswa nevanhuwo zvavo kana paine chikanganiso.
CBR (EN60947-2) Circuit breaker ine basa rekudzivirira marestial current rakavakwa mukati, rakakodzera kushandiswa kwemagetsi epamusoro >100A.
CBR inogona kunge iine hunhu hunogadziriswa uye haigone kugadziriswazve nevanhuwo zvavo kana paine chikanganiso.
Chinyorwa 722.531.3.101 chinotaurawo nezve EN62423; zvimwe zvinodiwa zvekugadzira zvinoshanda kuRCCB, RCBO neCBR pakuona F kana B residual current.
RDC-DD (IEC62955) inomiririra mudziyo wekuona wasara weDC current*; izwi rekuti michina yakagadzirirwa kuona DC fault current yakapfava mumashandisirwo ekuchaja muMode 3, uye inotsigira kushandiswa kweType A kana Type F RCDs mucircuit.
Muyero weRDC-DD IEC 62955 unotsanangura mafomati maviri ekutanga, RDC-MD neRDC-PD. Kunzwisisa mafomati akasiyana kuchaita kuti usatenge zvigadzirwa zvisingakwanise kushandiswa.
RDC-PD (mudziyo unodzivirira) unobatanidza 6 mA smooth DC detection uye 30 mA residual current protection A kana F residual current mumudziyo mumwe chete. RDC-PD contact inobviswa nemagetsi kana paine residual current error.
