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
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).
