Corrective factor
Peak arc voltage
Above: Mean curves show variation of total clearing time ( I2tt) and total clearing duration tt as a function of operating voltage U.
DC Application data
Left: Curves indicate permissible value
of time constant L/r as a function of the
DC working voltage
These curves show peak value Um of arc voltage which appears across the fuse-link as a function of operating voltage U @ cos ϕ= 0.15.
