Zogulitsa za S7-N ndi za m'zaka za m'ma 90 padziko lonse lapansi m'malo mwa

mbadwo wakale wa S7-N. Ali ndi ntchito yoteteza ya short circuit ndi overload,

ndipo amagwiritsidwa ntchito pogawa magetsi m'mafakitale, m'malonda ndi m'nyumba, komanso kuteteza

Ma mota amagetsi a fractional. Ndipo alinso ndi zabwino zambiri zoteteza kwambiri (mpaka

IP 20), mphamvu yothyoka kwambiri, yodalirika yogwira ntchito, yosavuta, yolumikizana ndi mitengo yambiri, yayitali

moyo ndi zina zotero. Amasinthidwa makamaka kuti azigwirizana ndi dera la AC 50Hz, 230V mu pole imodzi, 400V mu

mitengo iwiri, itatu, inayi yotetezera kupitirira muyeso ndi kufupika kwa magetsi. Pakadali pano, ilinso ndi

imagwiritsidwa ntchito poyatsa kapena kuzimitsa chipangizo chamagetsi ndi magetsi pansi pa mkhalidwe wabwinobwino.
