Abstract

A method for detection of a fuse failure of a protective fuse used to protect an associated load against overcurrent and/or against overload includes the steps of: measuring electrical current flowing through the protective fuse in a current path to the load by means of a current sensor element; determining one or more failure indicators adapted to indicate a possible failure of the protected fuse on the basis of the measured electrical current; and detecting automatically a failure of the protective fuse if the determined at least one failure indicator indicates a possible failure of the protective fuse and if the electrical current stopped to flow through the protective fuse or is below a predefined current threshold value.
