Fuse insert for semiconductor protection fuse, has cylindrical ceramic rod including high porosity than that of ceramic body such that force arising with fusion conductors affects ceramic rod, where fusion conductors are arranged around rod

摘要

The insert (10) has multiple fusion conductors (13) secured at mounting elements (11, 12), where the fuse insert is arranged in a container filled with solidified sand ceramic body of an over current protection device. A cylindrical ceramic rod (14) is centrally arranged in the fuse insert, and including a high porosity than that of the ceramic body such that a force arising with vaporizing fusion conductors affects the ceramic rod. The fusion conductors are arranged around the ceramic rod.
