UL Class G Time-Delay Midget Fuses

Able to withstand current overload for a short time, these fuses will not open when exposed to harmless temporary surges, such as when starting a motor. They have a smaller footprint than standard size fuses. Protect power distribution branch circuits from overcurrent. Use with Fuse Blocks for UL Class G Fuses.

Breakthrough current, labeled on the fuse as IR, is the maximum current that a fuse can safely stop in the event of a short circuit.
