Determines the peak arc voltage across the fuse terminals as a function of the applied voltage.
Clearing I2t vs. Operating Voltage
Correction factor to determine the clearing I2t for a fuse operating below its rated voltage.
DC voltage capability vs. Time Constant
Provides the DC voltage capabilities of
the fuse as a function of circuit time
constant. (L/R value)
