Zogulitsazi zimateteza ku zolakwika za dziko lapansi, kuchuluka kwa zinthu, ma circuit afupi komanso kupitirira mphamvu yamagetsi

kukhazikitsa kwa malonda ndi kwapakhomo. RCBO yokhala ndi neutral yolumikizidwa komanso phase yolumikizidwa

imatsimikizira kuti imagwira ntchito moyenera motsutsana ndi kutayikira kwa nthaka ngakhale pamene gawo ndi neutral zili

yolumikizidwa molakwika. RCBO yamagetsi ili ndi chipangizo chosefera chomwe chimateteza zoopsa za

osafunikira chifukwa cha ma voltage osakhalitsa ndi ma current currents. Chizindikiro chokhudzana ndi kukhudzana koyenera molingana ndi

ndi kope la maola 16 la lamulo la IEE la waya.
