Thaum ib qho MCB raug txuas mus rau tam sim no, cov kab xev bimetallic heats thiab khoov.Ib qho electromechanical latch raug tso tawm thaum MCB deflects ob-hlau strips.Thaum tus neeg siv txuas no electromechanical clasp rau kev ua hauj lwm mechanism, nws qhib lub microcircuit breaker hu.Yog li ntawd, nws ua rau MCB hloov tawm thiab txiav tawm tam sim no ntws.Tus neeg siv yuav tsum hloov tus kheej ntawm MCB los kho cov dej ntws tam sim no.Cov cuab yeej no tiv thaiv qhov tsis xws luag tshwm sim los ntawm ntau dhau tam sim no, overload, thiab luv circuits.
