Claim:
1. A fuse link comprising a porcelain housing with a star-core with wound fuse-elements, external end caps closed by plugs, star-core end caps with a ring-shaped first tap designed to ensure electric contact between the end cap of the star-core and the external end cap of the fuse link, and a spring-type striker pin positioned along the axis of the star-core, characterised in that each of the star-core end caps is provided with a second tap that is designed to centre the star-core relative to the axis of the fuse link and is located on the circumference of the star-core end cap at an obtuse angle (α) relative to the first tap, measured in a plane perpendicular to the axis of the fuse link, wherein said first and the second taps extend radially outward and axially away from a first edge of said star-core end cap and are provided with spring contacts bent inwardly from a second edge of said star-core end cap towards the direction of the longitudinal axis of the fuse link and in electrical contact with the wound fuse elements, and the spring-type striker pin is radially centred along the longitudinal axis of the fuse link by tongues of a disc spring that is mounted in one of the plugs closing the fuse link on the side where the spring-type striker pin is positioned.
