High Voltage IEC Fuses

DIN HV General Purpose Fuses for transformers

Limitor®-G General Purpose Fuses

Mersen HV fuse-links have been used for reliable protection in high-voltage switchgear and controlgear and high-voltage systems for decades. Limitor®-G HV fuses are general purpose fuses as defined in the IEC 60282-1 standard and dedicated to protect transformers against effects of short-circuit currents and low overcurrents. 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.
