A fuse includes a fuse body, two terminals, and a termination reinforcement. The fuse body surrounds a fusible element. The first terminal is located at one end of the fuse body and the second terminal is located at the other end of the fuse body. The fusible element is mechanically connected to the first and second terminals. The termination reinforcement is located at one end of the fuse body.

High breaking capacity fuses with metal reinforcements

A fuse assembly includes a housing and a wound wire operable as a fusible element. The housing has a cavity for the fusible element. The fusible element is formed by coating a wire with enamel and wrapping the wire around a core to produce enamel-coated wound wire. The enamel-coated wound wire is attached to the housing. The core is etched away until the core is dissolved and the enamel is stripped away.

Provided herein are protection devices, such as fuses, including a coiled fusible element. In some embodiments, a fuse includes a body including a center portion extending between a first end and a second end, and a first endcap surrounding the first end and a second endcap surrounding the second end. The fuse may further include a fusible element disposed within a central cavity of the body, wherein the fusible element includes a first coil disposed within the first endcap and a second coil disposed within the second endcap. The fusible element further includes a central wire extending diagonally between the first and second coils.

Coiled fusible element for high reliability fuse

An improved fuse element for use in a circuit protection fuse. The fuse element may include an insulating substrate portion and a conductive metallic portion disposed on at least one surface of the insulating substrate portion, wherein the metallic portion extends along, and is in continuous, intimate contact with the substrate portion. When the metallic portion melts and separates upon the occurrence of an overcurrent condition, the substrate portion bridges the resulting gap that is formed in the metallic portion and provides electrical arc suppression therein.
