□ The product is used in overload or short-circuit protection for elctric transformer . The current limiting means that the fuse will cut off the circuit before the short-circuit current reaches the peak value.
Current which passes the fuse when being 1.3 times of its specified electric current , Do not fusing for an hour ; When the current through the fuse is 2 times of its specined electric current , fusing in an hour ; Refer to its fusing feature curve in chart 1 when select the fuse.

□The fuse pipe is the main part of fuse , it is made by installing the fuse wire in the porcelain pipe , filling the quartz sand in the porcelain pipe and sealing to-ends of pipe.
For the fuse pipe with rated current below 7.5A and 35V rated voltage , its fuse wire is rolled on the special porcelain core , referening to chart 2.a for the fuse pipe with rated current above 7.5A , its fuse wire is hang in the porcelain pipe , referening to the chart .
