FLNR110-ID - 110Amp Fuse

FLNR110-ID - 110Amp Fuse

When uptime matters, and durable circuit protection is non‑negotiable, the Littelfuse FLNR110‑ID steps in as your workhorse. Engineered for industrial and commercial environments—think motor control centers, HVAC systems, distribution panels, and heavy‑duty machinery—this 110‑amp, Class RK5 time‑delay (dual‑element) fuse is built to give you long‑term reliability and fast visual diagnostics. Because the design accommodates surge currents (such as motor starts or transformer inrush) without tripping prematurely, your system stays running when lesser fuses might falter. On top of that, the built‑in indicating window lets you instantly spot when the fuse is blown—no guessing, no downtime wasted. With ratings of 250 V AC / 125 V DC and fault‑interruption capacity up to 300kA AC and 20kA DC, you’re getting serious protection in demanding settings.

Key Features and Benefits

• Visual indicator – The built‑in window clearly shows a blown condition, cutting down inspection time and helping maintenance crews react quickly.
• Time‑delay (slo‑blo) performance – The dual‑element design tolerates short bursts of surge current (such as motor startup or transformer inrush) without causing nuisance trips.
• High fault‑current interrupting rating – Rated to interrupt fault currents up to 300,000 A AC and 20,000 A DC, giving enhanced safety under extreme conditions.
• Knife‑blade style terminals – Designed for rugged industrial connections with blade‑mount terminations that provide solid mechanical and electrical contact.
• Dual‑element, current‑limiting design – Advanced protection for both overloads and short‑circuit events, extending equipment life and reducing risk of collateral damage.
• Trusted Littelfuse engineering – Manufactured to meet high standards of reliability and safety for demanding industrial applications.
