Time-Delay Inline Fuses
 |
Able to withstand current overload for a short time, these fuses will not open when exposed to harmless temporary surges. They are designed to handle high inrush loads from ballast transformers in fluorescent lighting systems. You'll need both a fuse and a fuse holder (not included) to add an inline fuse to an existing circuit. Fuses have a built-in cap that securely connects to the fuse holder. Also known as LMF fuses.
Breakthrough Current @ Voltage—Breakthrough current at voltage, labeled on the fuse as IR, is the maximum current that a fuse can safely stop in the event of a short circuit.
