High Speed Fuses
Square Body Flush End Contact — 690/700V (IEC/UL):
1000-4000A
690V (IEC) 1000-4000A
Arc Voltage
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.
Electrical Characteristics
The total clearing I2t at
rated voltage and at power
factor of 15% are given in
the electrical
characteristics. For other
voltages, the clearing I2t is
found by multiplying by
correction factor, K, given
as a function of applied
working voltage, Eg, (rms).
