PHP-Limitor®PT-MSL

Limitor®- PT Back-up Fuses, with Controlled Power Dissipation

Approvals & Standards
IEC 60282-1
VDE 0670 part 4
DIN 43625

Mersen HV fuse-links have been used for reliable protection in high-voltage switchgear and controlgear and high-voltage systems for decades. Limitor®-PT HV fuses are back-up fuses as defined in the IEC 60282-1 standard and dedicated to protect transformers against the 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.
