Abstract
A fuse including a fuse body having a main body portion formed of a dielectric material, a plurality of arc chambers formed in the main body portion, the arc chambers arranged in a matrix configuration, a conductor extending through the main body portion and intersecting the arc chambers, the conductor having bridge portions disposed within the arc chambers, the bridge portions being mechanically weaker than other portions of the conductor and configured to melt and separate upon the occurrence of an overcurrent condition in the fuse.
Claims15
A fuse comprising:
- a fuse body including a main body portion formed of a unitary block of dielectric material;
- a plurality of arc chambers molded into the main body portion, the arc chambers arranged in a matrix configuration;
- arc barriers disposed within solid portions of the unitary block of dielectric material between adjacent arc chambers, wherein the arc barriers are formed of metal plates;
- and
- a conductor extending through the solid portions of the unitary block of dielectric material and intersecting the arc chambers, the conductor having bridge portions disposed within the arc chambers and surrounded by air within the arc chambers, the bridge portions being mechanically weaker than other portions of the conductor and configured to melt and separate upon occurrence of an overcurrent condition in the fuse, wherein the conductor also extends through the arc barriers.
