Mersen GDL3 Ferraz Miniature Glass Fuse 3A

Mersen cartridge-style, time-delay glass fuses tolerate temporary inrush currents without opening, which prevents nuisance-blowing from equipment startups. Also called slow-blow glass fuses, they open to disconnect an electrical circuit when exposed to sustained loads and short circuits. GDL3 glass fuses provide overcurrent protection for low-current circuits in appliances, electronics circuit boards, and lighting fixtures. They typically have a voltage rating of 300VAC or less and are used for applications where they won't be exposed to high heat that could shatter the glass. Their small, cylindrical body is see-through for checking whether the fuse wire is intact or has melted. Ferraz Shawmut GDL3 is comparable to Eaton Cooper Bussmann FSTUL034.3472, MDQ-3, MDL-3-R, Schurter 34.3472, Littelfuse 313003.
