Bussmann offers a full line of ferrule style (cylindrical
clip-mounted) fuses, designed and tested to meet standards
and requirements in various locations around the world.
Their unique design and construction provide:
• Superior cycling capability
• Low energy let-through (I2t)
Ferrule fuses provide an excellent solution for small UPS,
small ac drives and other low power applications where
space is at a premium.
Voltage Rating
All Bussmann ferrule fuses — except 690V — have been
tested at their rated voltage. The 690V ferrule fuse has been
tested to the IEC 60269 standard, which requires clearing at
the rated voltage +5%.
Accessories
Ferrule fuses may be mounted in fuseclips, fuse holders,
fuse blocks or fused switches. A variety of products are
available. Please consult Bussmann Application Engineering
to discuss your requirement.

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

Arc Voltage
This curve gives the peak
arc voltage, UL, which
may appear across the
fuse during its operation
as a function of theapplied
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 correction
factor, Kp, is given as a
function of the RMS load
current, Ib, in % of the
rated current.

Arc Voltage
This curve gives the peak
arc voltage, UL, which
may appear across the
fuse during its operation
as a function of theapplied
working voltage, Eg, (rms)
at a power factor of 15%.
Specifications
Description: Ferrule style high
speed fuses.
Dimensions: See dimensions
illustration.
Ratings:
Volts: — 1000Vac/800Vdc

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).

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.
