Times vs current characteristics
URE URS URT
• 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 - Peak arc voltage
* The 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 show the peak value Um of the arc voltage
which appears across the fuse link as a function of the ope-
rating voltage U @ cos ϕ = 0.15.

D.C Applications data
• These curve indicate the permissible
value of time constant L/R as a function
of the D.C. working voltage.
• These Ipm values give the minimum
DC interrupting current in amps.
