Kufotokozera Kwachidule:

Chotsekera ma circuit cha Y7H chimagwiritsidwa ntchito mu dongosolo logawa magetsi kapena makina ogawa magalimoto

chitetezo cha overload ndi short-circuit mu dongosolo. Chogulitsachi ndi cha neoteric mu kapangidwe kake, chopepuka

kulemera kwake, kodalirika komanso kogwira ntchito bwino kwambiri. Ili ndi mphamvu zambiri zosweka, imatha kugwedezeka mwachangu,

ndipo chikwama chake ndi zinthu zake zimagwiritsidwa ntchito ndi mapulasitiki osapsa ndi moto komanso osagwedezeka.

yokhala ndi moyo wautali, imagwiritsidwa ntchito makamaka mu AC 50Hz/60Hz single-pole 230V kapena ziwiri, zitatu, zinayi 400V

circuit yotetezera overload ndi shortcircuit komanso yoletsa kusinthasintha kwa nthawi yochepa

Zipangizo zamagetsi ndi magetsi amagetsi nthawi zonse. Zogulitsazi zikugwirizana ndi IEC60898.
