Fuse 4A Glass GMF Series MPN:GMF-4

One-piece time-delay glass fuses with knob combine a fuse body and an insulating cap into a single unit for use as an in-line fuse. They fit into a compatible holder and are commonly used as in-line panel-mount fuses to protect fluorescent lighting fixtures and ballasts from overcurrent. Also called slow-blow glass fuses, they tolerate temporary inrush currents without opening, which prevents nuisance-blowing from equipment startups. They open to disconnect an electrical circuit when exposed to sustained loads and short circuits.

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.
