Littelfuse FLNR100 Time Delay Fuse
The Littelfuse FLNR100 Time Delay Fuse (100 Amp, 250V) is an electrical protection device designed to prevent damage from overcurrent in HVAC systems. It features a time-delay design that allows temporary inrush currents from motors and compressors while interrupting the circuit during sustained overloads or short circuits. Commonly used in air conditioners, furnaces, compressors, and electrical control panels, it safeguards critical components. Benefits include reliable circuit protection, reduced nuisance tripping, improved equipment safety, extended service life, and consistent performance in residential and commercial HVAC applications.
