ABSTRACT:
An electric cartridge fuse having a channel shaped fusible link section which carries a gas evolving core is provided with means for assuring positive axial positioning of the core without requiring deformation of the fuse link. The gas evolving core is provided with a lateral protrusion which extends through and operatively engages one of the perforations in the fuse link thereby positively axially positioning the core with respect to the fuse link.
