Top :Provides the DC voltage capability of a fuse as a function
of circuit time constant.
Remark:
When the fault current di/dt is very large, this condition can be
exceeded. It is the case for faults occurring in voltage
commutated inverters.
Below: Curves indicating peak arc voltage Um which may
appear across fuse terminals as a function of the DC working
voltage U, for various time constant L/R of fault path.
