Kutaya kwa Residual Curent Chipangizo kuti chiteteze, motsutsana ndi magetsi, kutsika kwa 50Hz kapena 60Hz, voteji yoyesedwa ya single phase 240V, 3 phase 415V, kutsika kwa 63A. Munthu akagwidwa ndi magetsi kapena mphamvu yotsalira ya dera ikapitirira mtengo wokhazikika, RCD imatha kudula mphamvu mkati mwa masekondi 0.1 yokha kuteteza chitetezo cha munthu ndikuletsa zidazo ku vuto lomwe limabwera chifukwa cha mphamvu yotsalira. Ndi ntchito iyi, RCD imatha kuteteza crcit ku overload ndi short circuit kapena ingagwiritsidwe ntchito posintha irtr motsatira dzina la coden. Imagwirizana ndi IEC898-87 & IEC 755.
