Iimpawu zeIi-MCCBs

Ii-MCCBsziyilwe ngemisebenzi emininzi enceda ukukhusela iinkqubo zombane ngendlela ekhuselekileyo nethembekileyo.Ezinye iimpawu eziphambili ze-MCCB ziquka:

Umthamo omkhulu wokwaphuka:I-molded case circuit breakersziyakwazi ukwaphula imisinga ukuya kumawaka ee-ampere, zizenze zilungele usetyenziso lwamandla aphezulu.
Indlela yohambo lwe-Thermal-magnetic: Izaphuli zesekethe ezibunjiweyo zisebenzisa indlela yohambo lwe-thermal-magnetic ukuze ibone kwaye iphendule kwi-overcurrent kunye neesekethe ezimfutshane.Izinto zohambo lwe-Thermal ziphendula kumthwalo ogqithisileyo, ngelixa izinto zohambo lwemagnethi ziphendula kwiisekethe ezimfutshane.
Ukusetwa kohambo oluhlengahlengiswayo: I-MCCBs inesetingi yohambo oluhlengahlengiswayo, oluvumela ukuba lubekwe kwinqanaba elifanelekileyo lesicelo esifunwayo.
Uluhlu olubanzi lweesayizi zesakhelo: Ii-MCCBs zifumaneka kwiintlobo ezahlukeneyo zobukhulu besakhelo, ezivumela ukuba zisetyenziswe kwizinto ezahlukeneyo. .Into yohambo lwe-thermal ibona ubushushu obuveliswa kukuhamba kwangoku kwisekethe kwaye ihambisa isaphuli sesekethe xa umsinga udlula umlinganiselo wohambo.Isiqalelo sohambo lwemagnethi siva umhlaba wemagnethi oveliswe yisekethe emfutshane kwisekethe, ikhubekisa isaphuli sesekethe ngokukhawuleza.
I-MCCB iqulathe indlu yeplastiki ebunjiweyo egcina indlela yohambo, abafowunelwa kunye neendawo zokuthwala zangoku.
Abafowunelwa benziwe ngezinto ezisebenza kakhulu ezifana nobhedu, ngelixa indlela yohambo ibandakanya umtya we-bimetallic kunye nekhoyili yamagnetic.
