Littelfuse POWR-PROThe Littelfuse POWR-PRO System of Fuses
gives you all the fuses you need for complete circuit protection coverage while reducing inventory and controlling costs.

The POWR-PRO System will:

  • Provide superior current-limiting protection with innovative, tested designs to prevent or reduce electrical system damage.
  • Reduce inventory by standardizing system protection.
  • Provide visual blown fuse indication with LLSRK_ID, and JTD_ID Indicator® fuses.
  • Reduce fuse replacement downtime with simple color coded fuse labels.

See for yourself why the POWR-PRO System gives you the widest range of circuit protection available today when compared to other systems.

Minimize Arc-Flash Hazards
Some of the factors that determine the severity of an Arc-Flash are the magnitude of the fault current and the time the current is allowed to flow. Current-limiting fuses applied within their currentlimiting range minimize the current flow and clear the fault in 0.00833 seconds or less. The more current-limiting the device and the faster it clears the fault minimizes Arc-Flash hazards and potentially reduces the amount of personal protective equipment (PPE) required. Using Littelfuse POWR-PRO Fuses will not only minimize Arc-Flash hazards with superior current limitation, but also provide maximum protection to equipment.

One of the quickest and easiest ways to reduce Arc-Flash hazards is to replace UL Class H, K5, and Class RK5 fuses with POWR-PRO currentlimiting Class RK1 or Class J fuses. For a given current and voltage rating, Class H, K5, RK5, and RK1 fuses are the same physical size. Therefore, it is easy to upgrade to better fuse protection and increased safety. To insure that only the most current-limiting fuse is used, it is recommended to change fuse clips to a rejection style for Class R or Class J fuses. Class J fuses provides the best option by assuring non-interchangeability with non-current-limiting fuses. Whichever your choice, the equipment should be labeled to inform maintenance personnel of the proper fuse replacement. The Littelfuse MROplus™ Program can assist with analyzing and upgrading from non-currentlimiting fuses.

Green label fuses provide all the inventory you need for:

  • Superior current-limitation from 1/10 – 6000 amperes.
  • Type 2 “No Damage” coordination with NEMA and IEC motor circuits.
  • Blown fuse indication (LLSRK_ID and JTD_ID).
  • Compact protection for motor circuits (JTD, JTD_ID, and CCMR).
  • 300,000 AIR to meet future trends toward higher available short circuit currents.
