Constructed with silver plated elements for low l2t and peak let-through, these advanced fuses virtually eliminate equipment damage due to surges and spikes. The L17T series fuse’s unique element geometry also provides cooler running temperatures, helping to minimize heat within enclosures.

  • Low l2t
  • Extremely current limiting
  • Low operating temperature
  • 170 VDC rating
