- Cartridge Fuse Link have a breaking capacity of 120kA. Rated voltages are 500V AC, rated current is up to 630A. It makes protection against short circuit, boasting current and opens circuit immediately. gL/Gg mark’s mean is line protection and this class of fuses are used for protection of cable and conductors. Fuses can operate to 1.6time higher of its rated value and breaking capacity of circuit for a 5In value in 5 seconds. The melting wires (fusible element) of the fuses cartridges are produced in different shape and sizes for various current rated. Over the melting wire small chambers are put together. In case of short-circuit and over load different section with the same diameter melt down and form practical sparks. As a result of the short-circuit current is extinguished and the heat is evenly transferred along the fuse.
