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