Dual-element fuse with chemical trigger element and methods of manufacture

An electrical fuse comprising:

• a short circuit fusible element, wherein the short circuit fusible element comprises:
• at least first and second perforated walls, the first and second perforated walls extending in spaced apart but generally parallel planes to one another, and
• at least one angled perforated wall extending from and linearly coupled to at least one of the first and second perforated walls by an attachment edge, the at least one angled perforated wall comprising one or more additional edges that are freestanding;
• and
• a trigger element connected in series with the short circuit fusible element, wherein the trigger element is chemically activated rather than mechanically activated to interrupt a predefined overload condition with a predetermined time delay.
