FLSR005-ID - 5 Amp Fuse

FLSR005-ID - 5 Amp Fuse

Get the industrial-grade protection your systems demand with the Littelfuse FLSR005ID 5 A Time‑Delay Indicating Fuse. Designed specifically for heavy‑duty environments, this cartridge‑style fuse features a dual‑element time‑delay design that guards against both overloads and short‑circuit events. With a voltage rating of up to 600 V AC and 300 V DC, and interrupting capability of 20,000 A at 300 V DC, this Class RK5 fuse delivers dependable performance even under challenging conditions. Engineered with a visual indication of fuse status, it helps you quickly identify and replace failed units, reducing downtime and maintenance costs.

Key Features and Benefits

• Time‑Delay (“slo‑blow”) dual‑element construction: Handles temporary inrush currents (such as motor starts) without nuisance openings, while still protecting against sustained overloads and faults.
• High voltage capability: Rated for use in systems up to 600 V AC and 300 V DC, making it versatile for industrial power distribution and control circuits.
• Industrial cartridge‑style build: Compact and rugged design fits standard fuse blocks or holders, ensuring secure installation in panel boards and equipment racks.
• Visual indicating feature: Built‑in blow indicator window that visibly shows when the fuse has opened, so you can spot the problem quickly and restore service faster.
• Reliable protection under harsh conditions: Dual‑element design plus current‑limiting behavior restricts fault currents, enhancing safety and protecting downstream gear.
