Moulded case Circuit Breakers yog cov khoom siv tiv thaiv hluav taws xob uas tsim los tiv thaiv hluav taws xob hluav taws xob los ntawm cov hluav taws xob ntau dhau.Qhov hluav taws xob ntau dhau no tuaj yeem tshwm sim vim yog overload lossis luv luv Circuit Court.Cov ntaub ntawv molded Circuit Court breakers tuaj yeem siv dav hauv ntau qhov voltages thiab zaus nrog lub ntsiab lus qis thiab sab sauv ntawm kev hloov pauv mus txawv tebchaws.Ntxiv nrog rau cov txheej txheem tripping, MCCBs kuj tuaj yeem siv los ua kev sib txuas ntawm phau ntawv hloov thaum muaj xwm txheej ceev lossis kev saib xyuas haujlwm.MCCBs yog tus qauv tsim thiab kuaj rau overcurrent, voltage surge, thiab kev tiv thaiv txhaum cai kom muaj kev nyab xeeb hauv txhua qhov chaw thiab kev siv.Lawv ua haujlwm tau zoo raws li kev hloov pauv rau lub voj voog hluav taws xob kom tshem tawm cov hluav taws xob thiab txo qis kev puas tsuaj los ntawm Circuit Court overload, txhaum hauv av, luv circuits, lossis thaum tam sim no tshaj qhov txwv tam sim no.

□: Rhuav lub peev xwm tus yam ntxwv code / S qhia hom qauv (S tuaj yeem raug tshem tawm) H qhia hom siab dua
Lus Cim: Muaj plaub hom ncej nruab nrab (N ncej) rau plaub theem khoom.Lub nruab nrab ncej ntawm hom A tsis yog nruab nrog dhau-tam sim no tripping caij, nws ib txwm hloov mus rau, thiab nws tsis tau hloov los yog ua ke nrog lwm yam peb ncej.
Cov ncej nruab nrab ntawm hom B tsis tau nruab nrog cov khoom siv tam sim no, thiab nws tau hloov los yog ua ke nrog lwm tus ncej (tus ncej nruab nrab yog hloov mus ua ntej yuav hloov OF) Cov ncej nruab nrab ntawm hom C yog nruab nrog tshaj- tam sim no tripping caij, thiab nws yog switched los yog off ua ke nrog rau lwm yam peb ncej (lub nruab nrab ncej yog switched rau ua ntej yuav switched OF) Lub nruab nrab ncej ntawm hom D yog nruab nrog over-tam sim no tripping caij, nws yog ib txwm switched rau thiab tsis hloov. ntawm los yog ua ke nrog rau lwm yam peb ncej.
