Corrective Factor:
Peak Arc Voltage:
The mean curves show the variation of the total
clearing time (I

) and the total clearing
duration t
t
as a function of operating voltage U.
Dissipated Power Corrective Factor:
Curve shows peak value Um of arc voltage which
appears across fuse link as a function
of the operating voltage U@ cos
ϕ
= 0.15
Curve enables computation of power losses P for a I
N
-
rated fuse as a function of RMS current I (as a multiple
of I
