326004 LITTLEFUSE FUSE 4A SLOBLO OR BUSS
The normal amperage value of the fuse. It is established by Littelfuse as a value of current which the fuse can carry, based on a controlled set of test conditions.
The amount of energy required to melt the fusing element.
Cold resistance is the resistance obtained using a measuring current of no more than 10% of the fuse's nominal rated current. The factory should be consulted if this parameter is critical to the design in question.
Indicates that the fuse can be relied upon to safely interrupt its rated short circuit current in a circuit where the voltage is equial to, or less than, its rated voltage. This system of voltage rating is covered by NEC regulations and is a requirment of Underwriters Laboratories as a protection against fire risk. The standard voltage ratings used by fuse manufacturers for most small-dimension and midget fuses are 24, 32, 63, 125, 250 and 600.
