<P>PROBLEM TO BE SOLVED: To improve circuit breaking performance of a fuse for a high-current circuit break. <P>SOLUTION: The fuse for high-current circuit break 10 is provided with a conductive part 14 electrically connected to an overcurrent protecting terminal (not illustrated) integrated with a main circuit. The conductive part 14 is provided with a fusion part 22 fusing by overcurrent, and parallel parts 20 coupled to either end of the fusing part 22 and parallel with each other. When an overcurrent flows at the parallel parts 20, tensile stress is generated at the fusing part 22 by repulsion of the parallel parts 20 based on the overcurrent to promote fusion of the fusion part 22, so that the overcurrent can be interrupted in a short time, and as a result, circuit breaking performance can be improved. <P>COPYRIGHT: (C)2009,JPO&INPIT |
