RCD yog ib lo lus dav dav siv hauv cov cai thiab cov cai ntawm kev coj ua, suav nrog RCCB, RCBO, thiab CBR. Ntawd yog, cov khoom siv uas muab cov khoom seem seem "tiv thaiv", uas yog, thaum qhov seem tam sim no tshaj li qhov tau teev tseg lossis lub cuab yeej raug kaw, lawv ntes cov seem tam sim no thiab hluav taws xob "cais tawm" lub voj voog. Contrary to RCM (Residual Current Monitor) uas yog siv los "nrhiav" residual tam sim no tab sis tsis muab residual tiv thaiv tam sim no-saib cov ntawv sau rau Tshooj 411.1 thiab cov qauv khoom uas tau teev nyob rau hauv tsab xov xwm 722.531.3.101
RCCB, RCBO, thiab CBR muab kev tiv thaiv los ntawm kev sib cais ntawm cov khoom siv hluav taws xob kom tsis txhob muaj qhov cuam tshuam tam sim no uas ua rau cov khoom siv mus los lossis kaw manually.
RCCB (EN6008-1) yuav tsum tau siv ua ke nrog OLPD cais, uas yog, fuse thiab / lossis MCB yuav tsum tau siv los tiv thaiv nws los ntawm overcurrent.
RCCB thiab RCBO muaj cov yam ntxwv ruaj khov thiab raug tsim los rov pib dua los ntawm cov neeg zoo tib yam thaum muaj kev txhaum.
CBR (EN60947-2) Circuit Court breaker nrog built-in residual tiv thaiv tam sim no muaj nuj nqi, haum rau ntau dua tam sim no daim ntaub ntawv> 100A.
CBR tej zaum yuav muaj cov yam ntxwv kho tau thiab tsis tuaj yeem rov pib dua los ntawm cov neeg zoo tib yam thaum muaj kev txhaum.
Tshooj 722.531.3.101 kuj hais txog EN62423; Cov qauv tsim ntxiv siv tau rau RCCB, RCBO thiab CBR txhawm rau kuaj pom F lossis B seem tam sim no.
RDC-DD (IEC62955) sawv cev rau cov khoom seem DC tam sim no nrhiav kom pom *; ib lub ntsiab lus dav dav rau cov cuab yeej siv tsim los txhawm rau txhawm rau txhawm rau DC qhov tsis raug tam sim no hauv kev them nyiaj hauv hom 3, thiab txhawb kev siv hom A lossis Hom F RCDs hauv Circuit Court.
RDC-DD tus qauv IEC 62955 qhia ob hom qauv, RDC-MD thiab RDC-PD. Nkag siab txog cov qauv sib txawv yuav xyuas kom meej tias koj yuav tsis yuav cov khoom uas siv tsis tau.
RDC-PD (cov cuab yeej tiv thaiv) sib koom ua ke 6 mA du DC tshawb pom thiab 30 mA A lossis F seem tiv thaiv tam sim no hauv tib lub cuab yeej. RDC-PD tiv tauj yog hluav taws xob cais tawm thaum muaj qhov cuam tshuam tam sim no.
