Patent ID: 7312688

Claim:
A fuse element having the form of a strip and comprising: a central metallic section having a part with a high melting point and a part with a low melting point embedded in the part with the high melting point; and, two lateral metallic sections with a high melting point, one of which in on one side and the other one of which is on another side of said central section; each of said lateral sections being joined to the high melting point part of said central section by a weld of fused material, said joined sections having the same thickness so that said strip has three coplanar sections, and the high melting point part and low melting point part of said central metallic section being adapted to alloy at said low melting point and thereby produce a eutectic that causes the strip to melt at a lower temperature than the high melting point part of said central metallic section.
