Medium Voltage IEEE Fuses

Back-Up R-Rated Ferrule Mount Fuses for Motor Protection

7.2 kV Ferrule Mount Motor

Mersen R-Rated fuses are current-limiting, high interrupting rating fuses intended for the short circuit protection of medium voltage motors and motor controllers. R-Rated fuses are back-up fuses that have a minimum interrupting rating, and must be coordinated with overload relays in combination motor starters. The motor starter manufacturer generally specifies the R-Rated fuse size. These fuses come with a 3 (size D) or 4 (size E) inch diameter barrels with ferrules and are mounted in spring reinforced clips.



  • The Amp-Trap® and 9F60 R-Rated fuses are UL Recognized.
  • Ferrule mounting for standard clips and interchangeability with other brands of fuses.
  • Current-limiting for superior equipment protection.
  • Metal embossed catalog number and manufacturing date for lasting identification.
  • Hookeye for non load-break isolation by hookstick.
  • On the 4.8kV an optional hookeye mounted in the factory is available.
  • On all other 3" barrel if a hookeye is required, use the operating eye 9F61AAW612.
  • Blown-fuse indicator to give positive identification of open fuse.
