1. Qhov ntsuas hluav taws xob ntawm lub fuse xaiv yuav tsum siab tshaj qhov hluav taws xob input ntawm lub voj tiv thaiv.
2. qhov ntsuas tam sim no ntawm UL fuse yog txiav txim siab raws li kev kuaj mob, thiab nws yuav tsum tsawg dua 75 feem pua ntawm tus nqi nominal thaum siv. Piv txwv li, lub voj voog khiav hauj lwm tam sim no yog 0.75A, thiab qhov tsawg kawg nkaus xaiv ntawm fuse tubes nrog ntsuas tam sim no yog 1A.
3. qhov ntsuas tam sim no ntawm IEC specification fuse raj tuaj yeem siv tau raws li 90 feem pua lossis 100 feem pua ntawm tus nqi nominal hauv kev siv tiag tiag. Piv txwv li, qhov hluav taws xob ua haujlwm tam sim no yog 0.9A, qhov tsawg kawg nkaus tuaj yeem xaiv nrog qhov ntsuas tam sim no ntawm 0.9A lossis 1A fuse raj.
4.Qhov sib txawv ntawm kev siv ambient kub, lub neej ua haujlwm ntawm lub fuse sib txawv, qhov kub thiab txias, lub neej ua haujlwm ntawm lub fuse luv dua; Hauv kev xaiv tiag tiag, qhov ntsuas tam sim no ntawm lub fuse yuav tsum tau nce ntxiv raws li cov coefficient. Peb cov khoom catalog tau qhia qhov ntsuas kub ntawm qhov nkhaus rau kev siv thaum xaiv cov raj fuse.
5.Lub peev xwm tawg ntawm lub fuse tube yog proportional rau nws ntim thiab inversely proportional rau cov ntsuas voltage. Ntawd yog, qhov loj dua qhov ntim lossis qhov me me ntawm qhov ntsuas hluav taws xob, qhov ntau dua qhov tawg ntawm lub fuse raj; Qhov me me los yog qhov siab dua qhov ntsuas hluav taws xob, qhov me dua qhov tawg ntawm lub fuse tube. Yog li ntawd, yog xaiv ib lub me me fuse raj, nws yog ib qho tsim nyog los txiav txim siab tias qhov luv luv Circuit Court tam sim no uas yuav tshwm sim nyob rau hauv kev tiv thaiv Circuit Court tsis loj heev; Yog hais tias qhov kev tiv thaiv Circuit Court tej zaum yuav muaj ib tug luv luv Circuit Court tam sim no, ib tug loj loj fuse raj nrog ib tug loj tawg tam sim no yuav tsum tau xaiv. Qhov tawg tam sim no ntawm txhua tus qauv thiab cov lus qhia tshwj xeeb yog cim rau hauv cov khoom lag luam catalog rau kev siv thaum xaiv cov raj fuse.
6. qhov surge I2T ntawm lub voj tiv thaiv yuav tsum tsawg dua 20 feem pua ntawm cov ntsuas I2T ntawm lub fuse raj, thiab lub raj fuse tuaj yeem tiv taus ntau tshaj 100, 000 surge shocks hauv lub voj tiv thaiv.
