Key features & benefits

Mersen HV fuse-links have been used for reliable protection in high-voltage switchgear and controlgear and high-voltage systems for decades.
Limitor®-PTD HV fuse-links are back-up fuses as defined in the standards: IEC 60282-1 and VDE 0670 T402 and dedicated to protect transformers in combination with air or gas insulated switchgear against the thermal and dynamic effects of short-circuit currents.
To guarantee high quality, Mersen uses the best materials: fuse-elements are in pure silver, caps are in copper coated with silver and bodies are in ceramic.
Limitor®-PTD HV fuse-links are perfectly designed to be used in combination with HV switchgear.
Siemens and Ormazabal recommend Limitor®-PTD HV fuses to be used in their gas-insulated switchgear.
