I-Molded case circuit breakers zizixhobo zokukhusela umbane ezenzelwe ukukhusela isiphaluka sombane ngokugqithisileyo.Oku kugqithiswa ngokugqithisileyo kunokubangelwa ngenxa yokugqithiswa okanye isiphaluka esifutshane.I-molded case circuit breakers ingasetyenziswa kuluhlu olubanzi lwee-voltages kunye ne-frequencies kunye nomda ochaziweyo ophantsi kunye ophezulu wezicwangciso zohambo oluhlengahlengiswayo.Ukongeza kwiindlela zokukhubeka, ii-MCCBs zisenokusetyenziswa njengokutshintsha kwezandla zokuqhawula uqhagamshelo kwimeko kaxakeka okanye imisebenzi yolondolozo.Ii-MCCBs zibekwe emgangathweni kwaye zivavanyelwe i-overcurrent, i-voltage surge, kunye nokukhuselwa kwempazamo ukuqinisekisa ukusebenza ngokukhuselekileyo kuzo zonke iimeko kunye nezicelo.Basebenza ngokufanelekileyo njengenguqu yokusetha kwakhona kwisekethe yombane ukukhupha amandla kunye nokunciphisa umonakalo obangelwa ukugqithiswa kwesiphaluka, impazamo yomhlaba, iisekethe ezimfutshane, okanye xa umbane udlula umda wangoku.
CJ:Ikhowudi yeshishini
M:Ityala elibunjiweyo lesaphuli sesekethe
1:Inombolo yoyilo
□:Umlinganiselo wangoku wesakhelo
□:Umthamo wokophulwa kwekhowudi/S uchaza uhlobo olusemgangathweni (S ingashiywa)H ichaza uhlobo oluphezulu
Qaphela: Kukho iintlobo ezine zepali engathathi hlangothi (i-N pole) kwimveliso yezigaba ezine. Ipali engathathi hlangothi yohlobo A ayixhotyiswanga yinto yokukhubeka yangoku, ihlala ilayita, kwaye ayivulwa okanye icinywe kunye nezinye. iipali ezintathu.
Ipali engathathi hlangothi yohlobo B ayixhotyiswanga ngento yokukhubeka ngokungaphaya, kwaye iyacinywa okanye icinywe kunye nezinye iipali ezintathu (ipali engathathi hlangothi iyalayitwa phambi kokuba icinywe)Ipali engathathi hlangothi yohlobo C ixhotyiswe ngokungaphezulu- into enokukhubeka yangoku, kwaye iyalayitwa okanye icinywe kunye nezinye iipali ezintathu (ipali engathathi hlangothi iyavulwa phambi kokuba icinywe) Ipali engathathi hlangothi yohlobo D ixhotyiswe ngesixhobo sokukhubeka sangoku, ihlala ilayita kwaye ayitshintshwa. phezu okanye ukucinywa kunye nezinye iipali ezintathu.
