Abstract
A fuse is described in which two fusing modes provide protection at low and high overcurrent conditions. The fuse comprises an oriented plastic substrate with a conductive layer adhered thereto.
Claims6
A fuse comprising:
- an oriented plastic substrate having a thickness proportional to the nominal current rating of the fuse;
- a conductive layer cooperatively adhering to said substrate and having a thickness of from 0.5 to 2 mils;
- wherein said fuse is characterized by a mechanical opening of said conductive layer at low overcurrent conditions and by a melting open of said conductive layer at high overcurrent conditions.
