Why should the DCR of a fuse be measured at a load of no more than 10% and an ambient temperature of 25°C ?

The internal resistance of a fuse is an index reflecting its consumed power in the circuit. The higher the resistance, the more power consumed. For fuses, two parameters can be used to check this index: voltage drop or cold resistance.

Voltage drop: the voltage drop reading after the fusing element reaches thermal balance under rated current. To measure it, apply rated current to the fuse and wait until the reading is stable. It may take a few minutes. It is a little inconvenient and time-consuming.

Cold resistance: the reading of cold resistance basically under no load condition, easy and fast.

Therefore, the cold resistance method is always preferred for fuse check. The load of less than or equal to 10% means basically no load or heating condition, so there will be no thermal balance process, while the ambient temperature itself has a certain effect on fuse performance. All performance indexes of a fuse are parameters in ordinary atmospheric condition, i.e. 25°C. The cold resistance of a fuse, if not measured under the above-mentioned conditions, may not be accurate.
