Abstract

The present invention relates to an electrical fuse having a series circuit formed by a PTC element and a fusible conductor. To create an electrical fuse of above-mentioned type having an automatic trigger adjustment to ageing phenomena or increase of nominal resistance of the PTC element and having a simple and compact structure of the whole circuit it is suggested that the PTC element (2) and the fusible conductor (3) have close thermal coupling.
