Intuitively hais lus, yog cov khoom ntawm lub raj lub cev yog txawv, ib tug yog iav, ib tug yog ceramic. Tab sis los ntawm kev ua haujlwm ntawm qhov pom, qhov kev ua haujlwm tawg-pov thawj ntawm ceramics yog qhov zoo dua li cov iav raj fuses.
Txawm hais tias lub fuse ceramic yog luv luv, peb lub qhov muag tsis tuaj yeem pom, thiab saib lub iav fuse pom tau, ceramic fuse tsis yooj yim tawg, tab sis lub iav raj fuse yog ib qho yooj yim tawg.
Tus nqi ntws ntawm cov raj ceramic yog siab dua li ntawm cov iav raj. Cov xuab zeb quartz nyob rau hauv lub raj ceramic tuaj yeem txo qhov kub thiab tua cov arc. Thaum qhov tam sim no tshaj lub peev xwm nominal, lub iav raj tsis tuaj yeem hloov cov raj ceramic. Tsis tas li ntawd, tsis txhob siv cov raj ceramic es tsis txhob iav raj, txwv tsis pub nws yuav poob kev tiv thaiv. Fuse yog thermal nyhuv, uas ceramic raj fuse muaj cua sov dissipation zoo, thiab lub tshav kub dissipation ntawm iav raj fuse tsis zoo, yog li tam sim no ntawm ceramic raj fuse yog loj dua iav raj.
Vim tias qhov sib txawv ntawm cov dej ntws tam sim no, iav fuse feem ntau yog siv rau ntawm txoj kab uas tsis tshua muaj tam sim no thiab ceramic fuse feem ntau yog siv rau ntawm txoj kab uas muaj tam sim no siab. 314 (10AH / 250V) koj tuaj yeem ntsuas qhov kev tiv thaiv los ntawm kev ntsuas lub 'meter' rau luv luv Circuit Court. Yog tias nws tau txiav txim siab tias tsis muaj qhov luv luv, koj yuav tsum nqa cov yeeb nkab pov hwm mus rau lub khw muag khoom lossis lub khw muag khoom siv hluav taws xob raws li tib qho kev qhia tshwj xeeb thiab cov tsos ntawm kev yuav khoom tom qab hloov.
