Melt blown, to carefully analyze the reasons blown fuse, the possible reasons are: 1) Short-circuit or overload fault and normal operation of the fuse; 2) Melt the use of time is too long fuse factory direct, melt due to oxidation or fuse high temperature operation, the melt characteristics change misjudgment; 3) melt equipped with mechanical damage, making it smaller cross-sectional area caused by wrong diagnosis in operation. Plug-in fuse: It is commonly used in the 380V and below the voltage level of the end line, as a distribution feeder or short-circuit protection for electrical equipment.
