Abstract: A fuse link used in alternate current medium- or high-voltage systems with a current frequency of 50 Hz includes a spring-type striker pin and is designed for the protection of electrical devices against consequences of short circuits and overloads. A porcelain housing with a star-core, external end caps closed by plugs, star-core end caps with a ring-shaped first tap designed to ensure electric contact between the star-core end cap and the external end cap of the fuse link is also included. A spring-type striker pin is positioned along the axis of the star-core. Each of the end caps of the star-core is provided with an additional second tap designed to centre the star-core relative to the axis of the fuse link. The spring-type striker pin is centred along the longitudinal axis of the fuse link.
