Umzi-mveliso kunye nabavelisi baseTshayina i-N7 III

N7 III

I-earth leakage circuit breaker (RCD) N7 III iyahambelana nemigangatho ye-VDE

0664, CEE27 kunye neBS 4293. Ingayinqumla isekethe yempazamo ngoko nangoko xa

ingozi yokutshayiswa okanye ukuvuza komhlaba kumgca wesiqu. Ngoko ke kufanelekile ukunqanda ingozi yokutshayiswa

kunye nomlilo obangelwa kukuvuza komhlaba. I-N7 III RCD ilungele ukusetyenziswa kwiintlobo ngeentlobo zezityalo,

amashishini, izakhiwo, izakhiwo, urhwebo, izindlu zeendwendwe kunye neentsapho. Ingasetyenziswa

iisekethe ukuya kuthi ga kwisigaba esinye sama-230/240V, isigaba sesithathu sama-400/415V, ama-50 okanye ama-60Hz.
