Mersen PT fuses are current-limiting fuses with high interrupting rating, used for the primary winding protection of potential transformer. They are small dimension ferrule type fuses and mount in standard clips. Current ratings are from 0.25A to 10A. FEATURES/BENEFITS:

  • Ferrule mounting for standard clips and interchangeability with other brands of fuses.
  • Current-limiting for superior equipment protection.
  • Non-venting for silent operation.
  • Metal embossed catalog number and manufacturing date for lasting identification.
  • Blown-fuse indicator to give positive identification of open fuse fuse is available on the 9F60 series. APPLICATIONS:
  • Primary protection for potential transformers (PT) or control power transformers (CPT). Length Clip Centers Diameter Ferrule Length RATINGS: Amp-Trap A240T
