FLSR003-ID - 3Amp Fuse

FLSR003-ID - 3Amp Fuse

Precision‑designed for demanding industrial and commercial electrical systems, the Littelfuse FLSR003ID fuse delivers reliable, high‑performance protection where it matters most. With a continuous current rating of 3 amps and rated for 600 VAC (and 300 VDC), this cartridge‑style fuse is built to handle high fault currents while accommodating temporary surges such as motor start‑ups or transformer energizations. The dual‑element, time‑delay (slo‑blo) design means you won’t face nuisance trips when inrush currents occur—and the built‑in visual indicator gives a clear, instant signal of fuse status, significantly cutting troubleshooting time and avoiding costly system downtime. Whether you’re upgrading an existing panel or specifying new equipment, the FLSR003ID brings dependable protection, clear diagnostics, and peace of mind for critical circuits.

Key Features and Benefits

• Advanced dual‑element, time‑delay design: Provides both superior short‑circuit interruption and sustained overload handling, which helps maintain system continuity.
• Visual indicator window built‑in: Lets technicians spot a blown fuse at a glance, reducing downtime and maintenance costs.
• Handles surge conditions: Time‑delay capability accommodates inrush currents from motors and transformers without unwanted fuse openings.
