Lub peev xwm hloov kho qhov chaw mus ncig ua rau cov neeg siv kho cov kev tiv thaiv kom tau raws li cov kev xav tau tshwj xeeb ntawm cov tshuab thiab cov txheej txheem sib txawv. Qib kev hloov kho no tsis yog tsuas yog txhim kho kev nyab xeeb ntawm cov khoom siv xwb, tab sis kuj pab txhim kho kev ntseeg siab thiab kev ua tau zoo ntawm cov chaw ua haujlwm.
Tsis tas li ntawd xwb, cov MCCBs uas hloov tau zoo yog qhov zoo tagnrho rau kev siv hauv kev lag luam thiab kev nyob hauv tsev uas muaj ntau yam khoom siv hluav taws xob sib txawv. Txij li cov tsev ua haujlwm thiab cov khw muag khoom mus rau thaj chaw nyob, cov circuit breakers no tuaj yeem hloov kho kom muab kev tiv thaiv zoo tshaj plaws rau ntau yam khoom siv hluav taws xob thiab cov khoom siv. Qhov kev hloov pauv no ua kom ntseeg tau tias cov kab ke hluav taws xob raug tiv thaiv los ntawm kev phom sij thaum ua kom muaj kev ua haujlwm zoo thiab kev tswj hwm hluav taws xob.
Qhov xwm txheej ntawm cov khoom siv hluav taws xob molded case uas hloov tau kuj tseem ua lub luag haujlwm tseem ceeb hauv kev saib xyuas thiab daws teeb meem. Los ntawm kev kho qhov chaw tiv thaiv kom zoo, cov neeg ua haujlwm saib xyuas tuaj yeem ua kom ntseeg tau tias cov khoom siv hluav taws xob teb tau zoo rau cov teeb meem uas yuav tshwm sim hauv lub tshuab hluav taws xob. Txoj kev saib xyuas ua ntej no pab txheeb xyuas thiab daws cov teeb meem ua ntej lawv nce siab, txo qhov tsis ua haujlwm thiab txo qhov kev pheej hmoo ntawm kev ua tsis tiav ntawm hluav taws xob.
Ntxiv rau qhov yooj ywm, MCCB uas hloov tau no tau tsim los ua kom tau raws li cov qauv kev nyab xeeb siab tshaj plaws, muab kev tiv thaiv overcurrent thiab luv luv. Cov khoom siv no raug kuaj xyuas kom zoo kom ntseeg tau tias lawv ua tau zoo thiab ntseeg tau, ua rau cov neeg siv muaj kev thaj yeeb nyab xeeb thaum lawv paub tias lawv cov kab ke hluav taws xob tau tiv thaiv zoo. Nrog MCCB uas hloov tau no, cov neeg siv tuaj yeem tswj hwm kev nyab xeeb hluav taws xob ntawm lawv cov kev teeb tsa, paub tias lawv muaj kev daws teeb meem uas siv tau ntau yam thiab txhim khu kev qha.
Hauv kev xaus lus, lub tshuab hluav taws xob hloov kho tau yog ib qho khoom siv tau ntau yam thiab tseem ceeb hauv kev tiv thaiv hluav taws xob. Lawv lub peev xwm hloov kho rau ntau yam khoom siv hluav taws xob thiab muab kev teeb tsa kev tiv thaiv tshwj xeeb ua rau lawv yog ib qho khoom muaj nqis hauv kev lag luam, kev lag luam thiab thaj chaw nyob. Los ntawm kev muab kev ywj pheej, kev ntseeg siab thiab kev nyab xeeb, MCCBs hloov kho tau pab txhim kho kev ua haujlwm zoo thiab kev nyab xeeb ntawm cov kab ke hluav taws xob, ua rau lawv yog qhov kev xaiv tseem ceeb rau kev teeb tsa hluav taws xob niaj hnub.
