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 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.
