Kufotokozera Kwachidule:

Chotsekereza magetsi chopangidwa ndi M4 series molded case circuit breaker, ndi dera loyenera la AC 50/60Hz, voltage yoteteza magetsi yovomerezeka 690 V (M4-125 500V), voltage yogwiritsira ntchito yovomerezeka AC 690V kapena pansi pake, current yogwira ntchito yovoteredwa 12.5-1600A, kuti igawire mphamvu zamagetsi komanso zosachitika kawirikawiri popanga ndi kuswa magetsi munthawi yabwino. Ma circuitbreaker amapatsidwa ntchito yoteteza ku overload ndi short circuit ndi undervoltage. Ma circuit breaker amatsatira muyezo wa IEC60947-2. Ma circuit-breaker ndi oteteza kawiri (Mu m=250A kapena kupitirira apo), dera lowongolera la zowonjezera limasiyanitsidwa ndi dera lalikulu, ndipo silifunika kutsegula chivundikiro cha dera lotsekereza magetsi mukayika zowonjezera.
