FLNR010-ID - 10Amp Fuse

FLNR010-ID - 10Amp Fuse

When you need dependable protection for power‑hungry machines and critical electrical systems, the Littelfuse FLNR100ID delivers. This 100 Amp, knife-blade time-delay fuse is engineered to keep industrial panels, motor circuits, and power distribution networks safe — even under the toughest operating conditions. With its dual-element design, it handles short circuits and provides extra headroom for surge currents from motor starts or transformer energizing, helping prevent nuisance trips and unexpected downtime.

Key Features and Benefits

• Knife-Blade Termination: Makes installation fast and secure, ensuring a tight fit in heavy-duty fuse blocks and disconnects for reliable conductivity and minimal maintenance hassles.
• Dual-Element, Time‑Delay Operation: Offers classic overload and short-circuit protection while allowing temporary surges — like motor start‑up currents — to pass without blowing the fuse prematurely.
• Built-In Visual Indicator: Lets technicians instantly see if the fuse has operated, cutting troubleshooting time and speeding up maintenance.
• High Interrupting Capacity: Designed to interrupt up to 300,000 A AC or 20,000 A DC fault current, safeguarding equipment even in the most severe short-circuit events.
• Durable Construction for Industrial Demands: Built to withstand harsh conditions typical of manufacturing plants, light industrial facilities, and heavy commercial installations.
