Peak Arc Voltage:
LCW : Size 10x28
LEW & LEWI : Size 17x27 I ≤ 80
LEW & LEWI : Size 17x27 I ≥ 100
Corrective factor :
Peak arc voltage :
The mean curves show the variance of the total
clearing time (I2t) 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 the operating
voltage U @ cos ϕ = 0.15.
