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%.
Power Losses
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 correc-
tion factor, Kp, is given as
a function of the RMS load
current, Ib, in % of the
rated current.
Features and Benefits
Excellent dc performance
Low arc voltage and low energy let-through (I2t)
Low watts loss
Superior cycling capability
Typical Applications
DC common bus
DC drives
Power converters/rectifiers
Reduced voltage starters

Electrical Characteristics
Total Clearing I2t
The total clearing I2t at
rated voltage and at power
factor of 15% are given in
the electrical characteris-
tics. For other voltages, the
clearing I2t is found by mul-
tiplying by correction fac-
tor, K, given as a function
of applied working voltage,
Eg, (rms).
