• These curves indicate, for each rated current, the pre-arcing time vs. the R/M.S. pre-arcing current.
• Tolerance for the mean pre-arcing current ± 10%

Corrective factor
* The mean curves show the variation of the total
clearing time (I

tt) and the total clearing duration tt
as a function of operating voltage U
Peak arc voltage
This curve show the peak value Um of the arc voltage
which appears across the fuse link as a function of the
operating voltage U @ cos
