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.

The total clearing I

rated voltage and at power
factor of 15% are given in
the electrical characteris-
tics. For other voltages,
the clearing I

t is found by
multiplying by correction
factor, K, given as a func-
tion of applied working
voltage, Eg, (rms).

• Watts loss provided at rated current.
• Microswitch indicator ordered separately. See accessories on pages 179-180.
Rated Current
The rated current of this fuse range has been given with
copper conductors that have a current density of 1.3 A/mm
2
(IEC 60269-4). For conductor cross section according to IEC
60269-1, the fuses must be derated. Please contact Cooper
Bussmann for application assistance.
