Vim qee cov tuam txhab lag luam tsis muaj lawv tus kheej DC fuse khoom, lawv siv AC fuses hloov. Nws yog ua tau los ntawm cov tswv yim pom. Txawm li cas los xij, raws li cov laj thawj kev nyab xeeb tau hais los saum toj no, thaum AC fuses siv hauv DC Circuit Court,tnws voltage yog qis dua qhov tseeb.Siab siv. Piv txwv li, Siemens' 1000V AC AC ceev-acting yog txwv rau 440V DC circuits. American EATON'S BUSSMANN AC 700V fuse kuj ua raws li 1.3-1.4 voltage poob coefficient thaum siv rau DC. Nws tsuas yog siv hauv 500V DC circuits. Ib qho kev tiv thaiv kev nyab xeeb tau lees paub los ntawm kev lag luam hluav taws xob thoob ntiaj teb.
DC FUSE zoo li peb FDS-32. Peb qhov ntsuas hluav taws xob yog 1000V, nws tuaj yeem siv rau txhua qhov hluav taws xob nrog qhov hluav taws xob qis dua 1000V.
