Imiqathango yokusetyenziswa:1. Ubushushu be-ambient ayikho ngaphezulu kwe +40℃, hayi ngaphantsi kwe -40℃
2. Umphakamo awudluli kwi-3000m
3. Esona santya somoya siphezulu asidluli kwi-35m/s
4. Amandla enyikima akufunekanga adlule kwi-8 degrees
Isiphumo:ityhubhu ye-fuse esisigxina kunye nocingo olukhokelela ngaphandle.Xa i-fuse ixhunywe kwisiphaluka, i-melt idibaniswe kwichungechunge kwisiphaluka, kwaye umbane wangoku uhamba nge-melted.Xa isiphaluka esifutshane okanye i-overcurrent isenzeka kwisiphaluka, i-current through the melt yenza ukuba kushushu;xa ifikelela kwiqondo lokushisa elinyibilikayo lensimbi etyhidiweyo, iya kuxubha ngokwayo, kwaye isiphaluka sephutha siya kunqunyulwa kunye ne-arc yokutshisa kunye nenkqubo yokucima i-arc ukuze idlale indima yokukhusela.
