Specifically designed for short circuit protection of
Telecommunications circuits, the Littelfuse L17T series
fuses provide reliable protection of sensitive DC power
distribution systems. Constructed with silver plated elements
for low I
2
t 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.
