Qhov kub ntawm ib puag ncig me me los yog paub txog kev ua haujlwm kub hauv lub fuse, qhov ua haujlwm ntawm lub fuse siab dua, qhov kub ntawm ib puag ncig, thiab qhov kub dua thaum lub fuse ua haujlwm, lub neej luv dua. Qhov ntsuas ntawm ntau qhov ntsuas tau xa mus rau ntawm 25 degree C. Yog tias qhov ntsuas kub ntawm qhov chaw me me yog siab, qhov ntsuas kub ntawm cov fuse yuav tsum raug txiav txim siab.
Piv txwv li: Lub fuse melting ceev yog siv nyob rau hauv ib qho chaw me me ntawm 90 degree C thiab 1.5A tam sim no. Tus nqi txo (TF) yog 95 feem pua.
Yog tias xaiv IEC specification fuse, ces qhov ntsuas tam sim no yog: in/ tf {{0}}.5A/ 0.95=1,58 A Pom zoo 1.6A lossis 2A fuse;
Yog xaiv UL specification fuse, qhov ntsuas tam sim no yog: hauv / tawm {{0}}.5A/0.75x0.95=2.1A Lub 2.5A fuse yuav tsum raug xaiv .
