The Fuse Element adopts the accurately tested material, high purity silver, or silver-copper eutectic or nickle-chrome eutectic, based on different rated current. The fuse element wire is extruded by mold of high accuracy. The cross section is inspected by laser micrometer to ensure the accuracy, while careful assembly guarantees no crack, shrinkage or twist which affects the time-current accuracy.
