Description
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
I2t and peak let-through, these advanced fuses virtually
eliminate equipment damage due to surges and spikes. The
L17T series fuse unique element geometry also provides
cooler running temperatures, helping to minimize heat within
enclosures.
