  • Patent number: 9460882
    Abstract: A compact, high breaking capacity fuse that includes a top insulative layer, at least one intermediate insulative layer, and a bottom insulative layer arranged in a vertically stacked configuration. The at least one intermediate layer may have a hole formed therethrough that defines an air gap within the fuse. A first conductive terminal may be formed on a first end of the fuse and a second conductive terminal may be formed on a second end of the fuse. At least one fusible element may connect the first terminal to the second terminal, thus providing an electrically conductive pathway therebetween. A portion of the at least one fusible element may pass through the air gap defined by the hole in the at least one intermediate insulative layer.
    Type: Grant

  • Publication number: 20150009007
    Abstract: A compact, high breaking capacity fuse that includes a top insulative layer, at least one intermediate insulative layer, and a bottom insulative layer arranged in a vertically stacked configuration. The at least one intermediate layer may have a hole formed therethrough that defines a chamber having arc suppression material disposed therein. A first conductive terminal may be formed on a first end of the fuse and a second conductive terminal may be formed on a second end of the fuse. At least one fusible element may connect the first terminal to the second terminal, thus providing an electrically conductive pathway therebetween. A portion of the at least one fusible element may pass through the air gap defined by the hole in the at least one intermediate insulative layer.
