Hi-Tech current limiting fuses

Hi-Tech® is an industry-leading brand of current-limiting fuses with advanced designs to provide maximum protection in small, cost-efficient form factors to optimize value, reliability and reduce system lifecycle costs. With fault clearing capabilities in less than one-half cycle, Hi-Tech current limiting fuses reduce the let-through energy, thereby significantly reducing stress on equipment and increasing safety. 

Advantages

  • 100% factory tested and sealed for a long and reliable operating life
  • Some of the lowest current let-through values in the industry for increased protection
  • Rugged machined-brass end caps used for greater ferrule strength, resulting in less distortion and a more secure fuse attachment.
  • Patented damage sensor significantly reduces the risk of fuse failure
