31301.5

1.5Amp Continuous Current Rating, 250VAC Nominal Maximum Voltage Rating, 0.25" Diameter x 1.25" Length (Standard 3AG / 1G Ferrule Dimensions), Glass-Body Slow-Blow (Time-Delay) Small-Dimension Cartridge Fuse. Utilizing a spiral-wound dual-element filament matrix housed in a clear, high-dielectric glass cylindrical tube, it is precision-calibrated to withstand normal transient electrical inrush currents and temporary starting surges without nuisance tripping. It provides a highly reliable, delayed electrical cutoff barrier under sustained overcurrent conditions to protect downstream transformers, power supplies, and control circuit modules from devastating thermal damage. Equipped with nickel-plated brass end-cap terminals to ensure permanent low-resistance contact continuity under continuous full-load operating workloads. Exact part index: 31301.5 (Manufactured by Littelfuse 313 Series / Part 031301.5H). Industry Exact Equals: Bussmann MDL-1-1/2 / Mersen GDL1-1/2 / Edison MDL1.5.
