Corrective factor - Peak arc voltage
These mean curves show the variation of the total
clearing time (I2tt) and the total clearing duration tt
as a function of operating voltage U.
This curve shows the peak value Um of the arc voltage
which appears across the fuse link as a function of
operating voltage U @ cos ϕ= 0.15.
