MCB yog dab tsi?
Miniature Circuit Breaker (MCB) yog hom hluav taws xob hluav taws xob uas me me.Nws tam sim ntawd txiav tawm cov hluav taws xob hluav taws xob thaum lub sij hawm muaj kev tsis zoo nyob rau hauv cov khoom siv hluav taws xob, xws li kev siv hluav taws xob ntau dhau lossis hluav taws xob luv luv.Txawm hais tias tus neeg siv yuav rov pib dua MCB, lub fuse tuaj yeem ntes cov xwm txheej no, thiab tus neeg siv yuav tsum hloov nws.
MCB yog ib qho khoom siv hluav taws xob uas tiv thaiv cov xov hluav taws xob thiab kev thauj khoom los ntawm kev nkag mus rau tam sim no, tiv thaiv hluav taws thiab lwm yam kev pheej hmoo hluav taws xob.MCB muaj kev nyab xeeb dua los daws, thiab nws rov qab muaj zog sai.Rau overloading thiab tiv thaiv Circuit Court nyob rau hauv daim ntawv thov nyob, MCB yog qhov kev xaiv nrov tshaj plaws.MCBs yog qhov ceev heev los pib dua thiab yuav tsum tsis muaj kev saib xyuas.Lub tswv yim ntxiv ntawm ob-hlau yog siv nyob rau hauv MCBs los tiv thaiv kev dhau tam sim no thiab luv luv tam sim no.
