Plug-in fuse: it is commonly used in the end of the line voltage 380V and below grade Taizhou high voltage fuses, electrical equipment as a distribution feeder or short-circuit protection. Enclosed Fuse: Closed divided filler fuses and fuse no fuse two fillers, shown in Figure 3 and Figure 4. Filler with a square ceramic tube fuse generally Hangzhou high-voltage fuse, built quartz sand and melt Ningbo high-voltage fuse, breaking ability, for 500V voltage level below current levels 1KA following circuit. No filler sealed fuse will melt into the closed cylinder, breaking capacity smaller, less for 500V, 600A under the power grid or distribution equipment.
