Fast-Acting Lift Truck Fuses
 |
These fuses open circuits quickly when surges are detected. Use them on battery-operated lift trucks.
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.
