Cov qauv ntawm lub fuse (fuse) thiab cov khoom siv, feem ntau hais lus, feem ntau ntawm cov fuses (fuses) uas muaj peev xwm tawg qis yog cov iav plhaub, thiab cov fuses (fuses) uas muaj peev xwm tawg siab feem ntau muaj cov plhaub ceramic, ntau yam yog kuj tau ntim nrog ntshiab granular quartz khoom.
Raws li txoj cai, thaum lub kaw lus tiv thaiv tau txuas ncaj qha rau lub zog hluav taws xob hluav taws xob thiab lub fuse (fuse) muab tso rau hauv qhov hluav taws xob nkag, yuav tsum siv lub peev xwm tawg siab (fuse) . Nyob rau hauv feem ntau theem nrab circuits, tshwj xeeb tshaj yog thaum lub voltage qis dua lub hwj chim mov voltage, nws yog txaus los siv ib tug tsawg breaking peev xwm fuse (fuse).
