High Speed Fuses
Square Body DIN 43 620 — 690V (IEC): 10-800A
Class gR — Full Range Fuses
Arc Voltage
690V (IEC) 10-800A
This curve gives the
peak arc voltage, UL,
which may appear
across the fuse during
its operation as a
function of the applied
working voltage Eg ,
(rms) at a power factor
of 15%.

Watts loss at rated current
is given in the electrical
characteristics. The curve
allows the calculation of
the power losses at load
currents lower than the
rated current. The
correction factor, Kp, is
given as a function of the
RMS load current, Ib, in %
of the rated current.
K
The total clearing I2t at
rated voltage and at power 0,5
factor of 15% are given in 0,4
the electrical

voltages, the clearing I2t is 0,2
found by multiplying by
200 300 400
500
correction factor, K, given
as a function of applied working voltage, Eg, (rms).

*The RMS amp rating of this fuse range is given with open fuse bases connected to copper
conductors according to IEC 60269, Part 1, table 10. When used in enclosed fuse bases/
disconnects, derating factors have to be observed.
Please contact Cooper Bussmann for application assistance.
• Watts loss provided at rated current.
• Microswitch ordered separately. See accessories on page 185-186.
