Fuse 4A Glass GLR Series MPN:GLR-4

One-piece, fast-acting glass fuses with knob combine a fuse body and an insulating cap into a single unit for use as an in-line fuse to protect fluorescent lighting fixtures from overcurrent. They fit into a compatible holder to form a fuse assembly, which can be installed in each fixture on a branch circuit. In the event of a overcurrent, the faulty fixture will be isolated to prevent the shutdown of every fixture on a circuit. Also called fast-blow glass fuses, they open within seconds of being exposed to overloads and short circuits. They are highly sensitive to changes in current flow and don't tolerate temporary overload currents or power surges.

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.
