Littelfuse L17T Fuses Offer Superior Protection for Telecommunications Systems
The L17T series fuses are specifically designed for short-circuit protection of telecommunication systems. They are extremely current-limiting and offer reliable protection of sensitive DC power distribution systems. Constructed with silver-plated elements for low l2t and peak let-through, these advanced fuses eliminate equipment damage due to surges and spikes. The L17T Series fuse’s unique element geometry provides cooler running temperatures, helping to minimize heat within enclosures.
