Peak Arc Voltage
Size 36x27 I ≤ 350 (LMW & LMWI)
Size 36x27 I ≥ 400 (LMW & LMWI)
Size 2x36x27 I ≤ 700 (LMMW & LMMWI)
Size 2x36x27 I ≥ 800 (LMMW & LMMWI)
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
