of total operating I2t (I2tt) as function of the
prospective current Ipat 1000V or 850 V(*),
cos ϕ = 0.15.
The oblique lines indicate the corresponding total
operating time Tt, with pre-arcing time in brackets.
Time-current characteristics
Curves indicating pre-arcing time for each rated cur-
rent as a function of RMS value of pre-arcing current I.
- Tolerances on this current ± 8 %.
- Beyond 30 sec, small overloads must be eliminated
by another device.
- Curve CC’ represents the maximum times taken by the
associated device to clear small overloads; only its
horizontal line is represented. Its oblique line must be
plotted according to sketch, top right corner.
- The intersection of the fuse and CC’ curves indicates
the minimum breaking current Ipm of the fuse.
Curves indicating for each rated
current the peak value Icthat the current may
reach as a function of the prospective fault
current Ip.

Top: Curves indicating the maximum time
constant L/R of the fault path as a function of
the DC voltage U, for the rated currents in the
sizes indicated in the table.
Ipm (1) values indicate the minimum breaking
current in Amperes (A).
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.
