Cov khoom siv hluav taws xob uas siv cov khoom siv hlau ua cov yaj hauv series hauv ib lub voj voog. Thaum lub overload los yog luv-circuit tam sim no dhau los ntawm cov yaj, nws yuav fuse vim nws tus kheej cua sov, yog li tawg lub Circuit Court. Lub fuse muaj cov qauv yooj yim thiab siv tau yooj yim, thiab dav siv los ua cov cuab yeej tiv thaiv hauv lub tshuab hluav taws xob, ntau yam khoom siv hluav taws xob thiab khoom siv hauv tsev.
Fuses tuaj yeem siv rau hauv qhov chaw hauv qab no:
kev tiv thaiv kab mob;
Semiconductor ntaus ntawv tiv thaiv;
Transformer tiv thaiv;
kev tiv thaiv lub cev muaj zog;
Kev tiv thaiv capacitor;
Thaub qab tiv thaiv Circuit Court breakers.
