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. Use them to protect equipment—they are not designed for power distribution circuits. Designed for use with Fuse Blocks for Midget 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.
