1. A high breaking capacity fuse comprising:
a top insulative layer, a first intermediate insulative layer, a middle insulative layer, a second intermediate insulative layer, and a bottom insulative layer arranged in a vertically stacked configuration, the first intermediate insulative layer includes a first hole formed therethrough, the second intermediate insulative layer includes a pair of longitudinally-spaced holes formed therethrough,wherein the top insulative layer, the bottom insulative layer, the first intermediate insulative layer, second intermediate insulative layer, and middle insulative layer are each flatly bonded to each other;
a first air gap defined by the first hole and extending between the top insulative layer and middle insulative layer; a second and third air gap defined by the pair of longitudinally spaced holes and extending between the bottom insulative layer and the middle insulative layer; a first conductive terminal formed on a first end of the vertically stacked configuration; a second conductive terminal formed on a second end of the vertically stacked configuration; a first fusible element formed on a top surface of the middle insulative layer; and a second fusible element and third fusible element formed on a bottom surface of the middle insulative layer, wherein the first fusible element, second fusible element and third fusible element form part of an electrical path between the first conductive terminal and second conductive terminal. |
