Description
NT fuses have high breaking capacity and used for general protection against short circuits and current overloads. This fuses are mainly for the protection of power lines, cables and equipment which have a voltage rating of 500V. Compact versions are also available for low rated currents in every size. In the top of the fuse link, we have the fusing indicator. It is capable of withstanding high thermal shock and internal pressure because of the ceramic body which allows high breaking capacity. The fuses are manufactured according to IEC standards.
