A back up current limiting fuse with a temperature sensing wire is provided to resume electricity supply promptly and to prevent explosion and a fire of a distributing board by rapidly blocking a second accident due to heat of the fuse. A back up current limiting fuse includes a silica sand(2) and an element(4) inside a sealed porcelain tube(1). On a side of the fuse, a striker wire(9) is connected to a spring(7). A striker pin(8) is attached to an end of the spring. A temperature sensing wire(6) is connected between the striker wire and the spring. The temperature sensing wire is the same as a bimetal and is melt and cut at a predetermined temperature.
