Cov kab hluav taws xob me me (MCBs) yog cov cuab yeej tseem ceeb hauv kev tsim hluav taws xob hluav taws xob faib hluav taws xob, muab luv luv -circuit, overload, thiab tiv thaiv overvoltage. Lawv tsim nyog rau ib zaug -theem thiab peb-phase circuits nrog qhov ntsuas tam sim no ntawm 125A lossis tsawg dua. Lawv muaj cov txheej txheem kev khiav hauj lwm, kev sib cuag, ib qho chaw mus ncig, thiab arc -kev tua hluav taws. Cov kev sib cuag kaw manually los yog hluav taws xob, thiab chav mus ncig ua haujlwm qhib kev tiv thaiv thaum muaj kab txawv txav.
Cov hluav taws xob hluav taws xob me me muaj ntau yam tseem ceeb, suav nrog lub tshuab ua haujlwm, kev sib cuag, cov khoom siv tiv thaiv (xws li ntau yam kev mus ncig), thiab arc - tua hluav taws. Kaw ntawm cov neeg tseem ceeb feem ntau ua tiav manually lossis hluav taws xob. Thaum kaw, qhov pub dawb -tripping mechanism kaw nws hauv lub xeev kaw.
