Abstract
In order to safely protect high over current flowing into the main circuit at short-circuit without any explosion or fire, the enclosed cartridge fuse with a high interrupting capacity should be applied. But this fuse is impossible to be applied to an inner electronic circuit because of a limited space problem result from the miniaturization trend of products. Therefore, it is necessary to apply a sub-miniature fuse with a relatively small size. However the semi-enclosed fuse which is more free for an influx of air than the enclosed cartridge fuse and is possible to protect fuse elements with chemical and physical combination can be adoptable. But it has a limit of implementing the characteristic of a high breaking capacity. For these reasons, the Fe-42wt％Ni fuse elements alloy and fuse-link with less space were designed to increase a breaking capacity of sub-miniature fuse and its safety for fire and explosion was confirmed in this paper.
