Umehluko phakathi kwe-MCB, RCCB, ne-RCBO

1.I-MCB (I-miniature circuit breaker): Umsebenzi oyisisekelo ugcwele ngokweqile futhi uvikeleke umjikelezo omfushane, wenza njengento "ethuthukisiwe fuse" yemibuthano yezindlu, esusa kuphela ukuhamba kwamanje ngaphandle kokukhathazeka ngokushaqeka kukagesi.

2.I-RCCB (isephulelo sesekethe samanje sendawo): Umsebenzi oyisisekelo ukuvikela okuvikelwa kwamanje. Ihambela lapho ithola ukushaqeka kukagesi komuntu (ukuvuza kwamanje kuya emhlabathini) kepha akuvimbi ukulayishwa ngokweqile noma imibuthano emifushane.

3.I-RCBO (I-Residial Yamanje Yekephu Yesivikelo Esiphezulu Ngokuvikelwa Okungaphezulu): Kuhlanganisa imisebenzi ye-MCB (i-miniature circuit breaker) kanye ne-RCCB (i-Resigual Precial Breaker yamanje), okuhlinzeka ngokuvikelwa kathathu ngokugcwele ngokweqile, umjikelezo omfushane, nokuvuza kwamanje, okwenza kube okuphelele kakhulu ekusebenzeni.

Kalula nje, i-MCB ivikela "ukwehluleka kwesekethe," kuyilapho onogada be-RCCB bemelana ne- "Electric Shock." I-RCBBO ivikela ngokumelene nobabili.
