Chotsekera cha R7-125 series earth leakage circuit chagwiritsidwa ntchito makamaka pa AC 50 Hz, voltage yovoteledwa

230/400V, mphamvu yamagetsi yochokera pa 6A mpaka 63A, yokhala ndi kugwedezeka kwamagetsi kotuluka, kuchulukirachulukira, ntchito yoteteza mafunde afupiafupi, ndi zina zotero. Ikhozanso kuwonjezera ntchito yoteteza mafunde amagetsi ochulukirapo malinga ndi zomwe makasitomala akufuna; Imagwiritsidwa ntchito makamaka powunikira nyumba komanso kuteteza makina ogawa magetsi. Ikhoza kuwonjezera ntchito yoteteza mafunde ocheperako, kuchulukirachulukira malinga ndi zomwe ogwiritsa ntchito akufuna; Chogulitsachi chikugwirizana ndi muyezo wa IEC61009-1 ndi GB16917.7.
