Ib qho kev qhia dav dav yog xaiv qhov ntsuas fuse ntawm 125% txog 150% ntawm qhov tam sim no puv nkaus. Rau cov voj voog nrog cov motors lossis transformers, suav nrog qhov tam sim no inrush thaum lub sijhawm pib kom ntseeg tau tias lub fuse tsis tawg thaum lub sijhawm ua haujlwm ib txwm. Thaum tsis paub meej, sab laj nrog cov lus qhia kev sib koom tes tiv thaiv ntawm cov chaw tsim khoom siv lossis ntiav tus kws ua hluav taws xob tsim nyog.

Q: Kuv yuav ua li cas sim seb lub fuse cartridge 5x20mm puas tseem zoo?
A: Ib lub fuse cartridge tuaj yeem sim nrog lub multimeter teeb tsa rau kev sib txuas lossis kev ntsuas kev tiv thaiv. Lub fuse zoo yuav qhia qhov nyeem tsis kam qis (feem ntau tsawg dua 1 ohm rau 5x20mm fuse ntawm chav tsev kub). Lub fuse qhib yuav qhia qhov tsis kam tsis kawg (tsis muaj kev sib txuas). Nco ntsoov tias qee hom fuse - tshwj xeeb tshaj yog cov fuses ua haujlwm sai heev nrog cov ntsiab lus zoo heev - yuav qhia qhov tsis kam siab dua me ntsis txawm tias thaum zoo, tab sis yuav tsum tseem sau npe kev sib txuas. Lub fuse qhib meej yeej ib txwm ua tsis tiav thiab yuav tsum tau hloov.
