Electrical Characteristics
Total Clearing I2t
The total clearing I2t at rated 1.5
voltage and at power factor of
K
15% are given in the electrical 1.0
characteristics. For other volt-
ages, the clearing I2t is found
by multiplying by correction 0.5
factor, K, given as a function
of applied working voltage, 0.3
Eg, (rms).

This curve gives the peak arc 1600 UL
voltage, UL, which may
appear across the fuse dur- 1200
ing its operation as a function
of the applied working volt- 800

given in the electrical char- 1.0 Kp
acteristics. The curve

allows the calculation of the 0.6
power losses at load cur- 0.5
rents lower than the rated 0.4
current. The correction fac- 0.3
tor, Kp, is given as a func- 0.2
tion of the RMS load cur-
rent, Ib, in % of the rated
current.
