The L17T Series Telecommunications Power Fuses are specifically designed for short circuit protection of Telecommunications circuits. The L17T Series provides reliable protection of sensitive DC power distribution systems. Constructed with low I2t and extremely current limiting characteristics, the L17T Series fuses provide reliable protection of sensitive DC power distribution systems. This series is rated 170 VDC.
The L17T series from Littelfuse provides low‑I²t, current‑limiting fuses designed for short‑circuit protection in telecommunications DC power distribution. Rated at 170 VDC, the fuses cover a wide ampere range from 70 A to 1200 A and feature a silver‑plated element for low peak let‑through current and cooler operation.
The series is UL and CSA certified and is compatible with recommended fuse blocks such as the LTFD‑6001 and LTFD‑1200 series. Detailed specifications, ampere ratings, dimensions, and ordering information are provided in the sheet. This manual is written in Chinese.
