Recognized
This fuse preselection table indicates, for each size:
- rated current (or rating) In
- pre-arcing I2t (I2tp) at 1 ms
- total operating I2t (I2tt) at 660 V, f=50Hz cos ϕ=0.15, and for a total operating time from 8 to 10 ms
- dissipated power Pn at the rated current In, and at 0.8 In, in steady state
- breaking capacity at various voltages, checked by tests
made in accordance with IEC and American standards.

I2t Multiplier coefficient
Mean curve indicating variation of total I2t (I2t t) and total
operating time Ttin accordance with working voltage U.
Example:
Fuse 350 A in size 30.
Ip= 10 000 A U = 500 V
At 660 V
I2t t= 80 000 A2s Tt= 6 ms
At 500 V
I2t t= 80 000 x 0.72 = 57 600 A2s
Tt= 6 x 0.72 = 4.3 ms
Dissipated power Arc voltage
Curve indicating peak arc voltage Um which
may appear across fuse terminals as
function of working voltage U at cos ϕ= 0.15
Curve enabling calculation of dissipated
power P by a fuse rated IN, as a function
of the RMS current I, in multiples of IN, in
a steady state.

Maximum values of total
operating I2t and total operating
times
Left: Horizontal curves indicating the maximum
values of total operating I2t (I2tt) as function of the
prospective current Ipat 660 V, cos ϕ= 0.15.
The oblique lines indicate the corresponding total
operating time Tt, with pre-arcing time in brackets.
Time-current characteristics
Above, left: Curves indicating pre-arcing time for
each rated current as a function of RMS value of
pre-arcing current I.
- Tolerances on this current ± 8 %.
- Beyond 30 sec or 10 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.
Cut-off characteristics
Below, right: Curves indicating for each rated-
current the peak value Icthat the current may
reach as a function of the prospective fault
current Ip.

Time-current characteristics
Above, left: Curves indicating pre-arcing time for
each rated current as a function of RMS value of pre-

- Tolerances on this current ± 8 %.
- Beyond 30 sec or 10 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.

Remark:
When the fault current di/dt is very large, this condition can be exceeded. This is the case for faults
occurring in voltage commutated inverters.
