Hi-Rel Fuses

Key Features

  • Consistent minimum and maximum clear-times at overload currents regardless of vacuum conditions.
  • Solid body construction does not outgass and therefore is not subjected to the de-rating factors of Mil-Std-975.
  • Solid body construction can withstand greater vibration and shock exposure without damage.


These fuses are manufactured in the QPL approved factory. We have a unique range of the sole QPL listed solid body, current limiting fuses. These utilise a proprietary thick film technology for the aerospace and space industry. These products are primarily the product of choice for space programs, where they have been used successfully for over 30 years without any recorded failures.


  • Protection of power supplies, batteries and solar arrays
  • Isolation of redundant and branch circuits
  • Short protection from squib and jettison circuitry
