Mersen HV fuse links have been used for decades to provide reliable protection in high-voltage switchgear and switchgear. The Limitor -PTD product range protects transformers in combination with air or gas-insulated switchgear against the thermal and dynamic effects of short circuits. Mersen uses the best materials: fuse elements are made of pure silver, contact caps are made of silver-coated copper and the fuse body is made of ceramic. The Limitor -PTD high-voltage fuses are specifically designed for use in high-voltage switchgear. Siemens and Ormazabal recommend the use of Limitor -PTD HV fuses in their gas-insulated switchgear.
