 ●DC Cold Resistance are measured at <10% of rated current in ambient temperature of 25℃;

 ●Typical Pre-arching I2t are calculated at 10*In Current or 8ms.

Notes:

1. Derating depicted in this curve is in addition to the standard derating of 20% for continuous operation.

Example:For continuous operation at 75 degrees celsius, the fuse should be derated as follows:I = (0.80)(0.85)I_RAT= (0.68)I_RAT
