    摘要： A fuse includes multiple stacked layers, a first terminal, and a second terminal. The first terminal is connected to one end of a fusible element and the second terminal is connected to the other end. The stacked layers include first and second intermediate layers and a special layer. The first intermediate layer, which has a centrally disposed opening, is stacked on the first terminal and the second terminal. The second intermediate layer, also having a centrally disposed opening is stacked above the first intermediate layer, and the centrally disposed openings define a chamber above the fusible element. The special layer is located between the first intermediate layer and the second intermediate layer and includes one or more geometric elements. The geometric elements divide the chamber into two sub-chambers, the first sub-chamber being above the second sub-chamber.

    摘要： 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.

    摘要： Provided is a current fuse that can improve the rating while also preventing explosive scattering of metal in association with arc discharge and enabling reliable cutting off of a circuit. The current fuse (1) includes an insulating substrate (2), a main fuse element (3) disposed on the insulating substrate (2), and a sub-fuse element (4) disposed on the insulating substrate (2) and having a higher melting point than the main fuse element (3). The main fuse element (3) and the sub-fuse element (4) are connected in parallel.
