Iziphuli zesekethe ezincinci, edla ngokubizwa ngokubaIi-MCB, ziyinxalenye ebalulekileyo yeenkqubo zombane zanamhlanje. Sisixhobo esibalulekileyo sokhuseleko esikhusela iisekethe kwimithwalo emininzi kunye neesekethe ezimfutshane, sithintela ukonakala kwezixhobo kunye nenkqubo yonke. Eli nqaku liza kuxoxa ngokubaluleka kunye nendima yeiziphuli zesekethe ezincinci.
Omnye wemisebenzi ephambili ye-I-MCBkukujonga umsinga ohamba kwisekethe uze uwuphazamise ukuba kukho into engaqhelekanga. Uvula isekethe ngokuzenzekelayo, uphazamise ukuhamba kombane, ngaloo ndlela uthintela nawuphi na umonakalo onokubakho. Olu phawu lubaluleke kakhulu ekuthinteleni iingozi zomlilo ezibangelwa kukushisa kakhulu okanye iimpazamo zombane.
Iziphuli zesekethe ezincincizenzelwe ukusingatha amanqanaba ahlukeneyo ombane. Zifumaneka kwiindidi ezahlukeneyo, nto leyo evumela abasebenzisi ukuba bakhethe izixhobo ezifanelekileyo.I-MCBngokweemfuno zabo ezithile. Ezi zilinganiso zihlala zibonakaliswa ngee-amperes (A) kwaye zimele umsinga ophezulu onokudlula kwi-circuit breaker ngaphandle kokukhubeka.
Indlela yokusebenza yeiqhekeza lesekethe elincinciibandakanya i-electromagnet kunye nenxalenye ye-bimetallic. Xa kwenzeka i-overload okanye i-short circuit, umbane odlula kwi-I-MCBidlula umda wayo ophezulu olinganisiweyo. Oku kubangela ukuba i-bimetal igobe ngenxa yobushushu obandayo, ekugqibeleni ikhubeke kwisekethe. Xa kwenzeka umthwalo omkhulu okanye isekethe emfutshane, i-electromagnet ivala ngoko nangoko, inika ukhuseleko olukhawulezayo noluthembekileyo.
Iziphuli zesekethe ezincinciZineengenelo ezininzi kuneefusi zemveli. Zingaphinda zisetwe ngokulula emva kokukhubeka, nto leyo esusa isidingo sokutshintsha ngalo lonke ixesha xa kukho impazamo. Ukukwazi ukuseta kwakhona i-circuit breaker akugcini nje ngokonga ixesha kodwa kunciphisa neendleko zokulungisa. Ukongeza,Ii-MCBukubonelela ngokhuseleko oluchanekileyo noluchanekileyo ngokufumanisa nokuphendula kwiinguqu ezincinci kumbane wombane ngexesha elifanelekileyo.
Isishwankathelo,iziphuli zesekethe ezincinciziyinxalenye ebalulekileyo yeenkqubo zombane njengoko zibonelela ngokhuseleko olusebenzayo lokugqithisa kunye nolwe-short-circuit. Ukukwazi kwazo ukuphula isekethe ngokukhawuleza kunceda ekuthinteleni iingozi zombane kwaye kuqinisekise ukhuseleko lwabantu kunye nezixhobo. Ngokukhetha umlinganiselo ofanelekileyo, abasebenzisi banokwenza ngokwezifiso umgangatho wokhuseleko olufunekayo kwiseti yabo ethile yombane. Lilonke, ukutyala imali kumgangathoiqhekeza lesekethe elincinciKubalulekile ukugcina ukhuseleko nokuthembeka kwayo nayiphi na inkqubo yombane.
