Limitor® - PTS Back-up Fuses, with Low Power Dissipation and Thermal Striker
Mersen HV fuse-links have been used for reliable protection in high-voltage switchgear and controlgear and high-voltage systems for decades. For the Limitor®-PTS range, Mersen innovates with new fuse-element designs to reduce power losses and new thermal striker to prevent overheating in the fuse compartment of the switch gear. Mersen uses the best materials : fuse-elements are in pure silver, caps are in copper coated with silver and body is in ceramic. Limitor®-PTS HV fuse-links are dedicated to protect transformers in combination with air or gas insulated switchgear against the thermal and dynamic effects of short-circuits. Siemens and Ormazabal recommend Limitor®-PTS HV fuses to be used in their gas-insulated switchgear.
