FLSR090-ID - 90Amp Fuse Description
FLSR090-ID - 90Amp Fuse
Protect your industrial systems with the Littelfuse FLSR090ID Class RK5 Indicating Time‑Delay Fuse. Designed to deliver top‑tier performance and dependable protection, this 90‑amp fuse features knife‑blade style terminals that provide solid, vibration‑resistant connections in demanding environments. Its dual‑element, time‑delay (Slo‑Blo) design is especially suited for applications with heavy inrush currents—like motors, transformers, and large machinery—so you’re much less likely to get nuisance blows. Plus, the built‑in blown‑fuse indicator lets maintenance staff quickly spot and address a blown fuse, minimizing downtime and keeping your facility moving.
