ABSTRACT:
An electric fuse having a printed circuit type fusible element. A substrate of glass textile material impregnated with a polymerized melamine resin and alumina trihydrate is the carrier for the fusible element. The dispersion of the two above referred-to components is formulated to serve as adhesive medium between the glass textile material and its metal covering and as source of arc-quenching gases when subjected to the action of an electric arc. An addition of silane significantly enhances the bonding action of the melamine resin alumina trihydrate dispersion of the glass fiber substrate with the metal layer by which it is clad.
