Bussmann offers a complete range of North American blade
and flush-end style fuses and accessories. Their design and
construction were optimized to provide:
•
•
•
•
•
Low energy let-through (I2t)
Low watts loss
Superior cycling capability
Low arc voltage
Excellent DC performance
North American style fuses provide an excellent solution for
medium power applications. While there are currently no
published standards for these fuses, the industry has standardized on mounting centers that accept Bussmann fuses.
Voltage Rating
All Bussmann North American style fuses are tested at their
rated voltage. Bussmann should be consulted for applications exceeding those values.
Accessories
External and internal open fuse indication is available for
selected portions of the North American line. Fuseblocks are
available for most applications.

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,
E g , (RMS).
1.5
Arc Voltage
This curve gives the peak arc voltage,
U L , which may appear across the fuse
during its operation as a function of the
applied working voltage, E g , (RMS) at a
power factor of 15%.

Applications
Maximum Permissible Load Current
The rated current value of Bussmann fuses is based on the
ambient temperature in the space immediately below the
fuse of 20°C. The following graph gives correction factors (k)
for a range of temperatures (–40°C to +80°C). Maximum
permissible continuous load currents can be calculated by
applying the following formula:
Ib = In ≈ k ≈ (1 + 0.05 V) x Kb
where
Ib = Maximum permissible continuous load current
In = Rated current of fuse
k = Temperature correction factor
v = Velocity of cooling air in m/s (max. 5 m/s).
Kb = Fuse load constant 1.0
The maximum permissible continuous load current Ib of a
fuse can be checked empirically (i.e., by satisfying the formula below) by making simple voltage and temperature
measurements under actual operating conditions after the
fuse has been installed in its operating location and loaded
at the calculated Ib value:
E2
≈ (0.92 + 0.004t) ≤ N
E1
where
E1 = Voltage drop across fuse after 5 seconds
E2 = Voltage drop across fuse after 2 hours
t = Air temperature at start of test (°C)
N = Constant

Application Procedure
Step
Procedure
Remarks
(1) Select a short-blade fuse to permit
mounting of microswitch MSW710-1S
or 170H0069
1.1 Taking into consideration only the
continuous load current and ambient
temperature, from Table on page 54
tentatively select fuse 170M3669
400A, 660V).
—
(2) Determine I2 t (total clearing) at 440V.
2.1 See Table, page 54. Note I2t is
105,000A2s at rated voltage of 660V.
2.2 From the figure on page 55, note that
correction factor K = 0.65.
2.3 I2t660V ≈ K = I2t440V
105,000 ≈ 0.65 = 68,250
OK
(3) Determine maximum arc voltage
at 440V
3.1 From the figure on page 55, note that
maximum voltage at 440V is 925V
OK
(4) Determine maximum permissible
continuous load current Ib.
4.1 Per page 28 data,
Ib = In ≈ k ≈ (1 + 0.05V) ≈ Kb
Ib = 400A ≈ 0.8 ≈ (1 + 0) ≈ 1
Ib = 320A
—
(5) Plot a “line profile” showing the
expected load and overload currents.
Determine that overload and impulse
load currents do not exceed their
maximum permissible values.
(Item 2)
5.0 Calculate Imax per Table, page 4,
for each overload and impulse
load.
—
(Item 3a)
(Item 3b)
(Item 4)
5.1 Imax < 60% ≈ It
500A < 60% ≈ 950A
500A < 570A
5.2 Imax < 60% ≈ It
700A < 60% ≈ 1360A
700A < 780A
5.3 Imax < 70% ≈ It
700A < 70% ≈ 1150A
700A < 805A
OK
OK
OK
5.4 Imax < 70% ≈ It
1100A < 70% ≈ 1800A
OK
1100A < 1260A
The tentatively selected fuse 170M3669 with microswitch 170H0069 meets all application parameters; no further
selection would be necessary.

Current In Amperes
Calculation of Watt Loss
From the Table on page 54, watt loss at 400
amperes is 60 watts. The continuous load
current of 300 amperes is 75% of rated
current (400 amperes). From page 55, the
correction factor Kp = 0.5.
Watt Loss 75% = Watt Loss 100% ≈ Kp
= 60W ≈ 0.5
= 30 watts
Special Fuses
Other high speed fuses are available from
Bussmann with voltage ratings of 380 to
10,000 volts and current ratings up to 10,000
Amp in a single unit configuration. Fuses can
be supplied with open fuse, “pin” indicators.
Various types of microswitches are also
available (see page 58).

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,
E g , (RMS).
Arc Voltage
This curve gives the peak arc voltage,
U L , which may appear across the fuse
during its operation as a function of the
applied working voltage, E g , (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, K p ,
is given as a function of the RMS load
current, Ib , in % of the rated current .

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,
E g , (RMS).
Arc Voltage
This curve gives the peak arc voltage,
U L , which may appear across the fuse
during its operation as a function of the
applied working voltage, E g , (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, K p ,
is given as a function of the RMS load
current, Ib , in % of the rated current .

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,
E g , (RMS).
Arc Voltage
This curve gives the peak arc voltage,
U L , which may appear across the fuse
during its operation as a function of the
applied working voltage, E g , (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, K p ,
is given as a function of the RMS load
current, Ib , in % of the rated current .

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,
E g , (RMS).
Arc Voltage
This curve gives the peak arc voltage,
U L , which may appear across the fuse
during its operation as a function of the
applied working voltage, E g , (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, K p ,
is given as a function of the RMS load
current, Ib , in % of the rated current .

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,
E g , (RMS).
Arc Voltage
This curve gives the peak arc voltage,
U L , which may appear across the fuse
during its operation as a function of the
applied working voltage, E g , (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, K p ,
is given as a function of the RMS load
current, Ib , in % of the rated current .

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,
E g , (RMS).
Arc Voltage
This curve gives the peak arc voltage,
U L , which may appear across the fuse
during its operation as a function of the
applied working voltage, E g , (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, K p ,
is given as a function of the RMS load
current, Ib , in % of the rated current .

Indicators
Typower ZILOX fuses are available with three different indicator systems.
Visual Indicator
The indicator situated in one cover plate is clearly visible as
soon as the fuse has operated. The minimum voltage for
operating the indicator is 20V.
Type T Indicator
The indicator is situated on one cover plate with a cover
plate tag to accommodate an auxiliary switch. The minimum
voltage for operating the indicator is 20V. A special low
voltage indicator (1.5V) is available on request.
Type K Indicator
This indicator is situated on the fuse body. It is covered by
an adaptor for snap-on mounting of an auxiliary switch. The
operating voltage of the indicator is 1.5V. As a matter of
safety, the factory mounted adaptor must not be removed
from the fuse.
Microswitch
The Typower ZILOX fuses with either type T indicator or
type K indicator can be equipped with a microswitch for
remote electrical indication of fuse operations. All microswitches have one normally open and one normally closed
contact. Ratings are 2A, 250 Vac.

General Information
Designed and tested to:
• BS 88: Part 4
• IEC 269: Part 4
• U.L. Recognized
Bussmann offers the industry’s widest range of British style
semiconductor fuses and accessories.
Bussmann British style products use innovative arc
quenching techniques and high grade materials to provide:
British style fuses are typically found in equipment manufactured in the United Kingdom or British Commonwealth
countries. However, North American manufacturers have
begun to specify British style fuses — particularly in UPS
applications at 240 volts or less — to take advantage of
their size, performance and cost benefits.
Voltage Rating
All Bussmann British style fuses are tested to IEC 269: Part
4. This standard requires a test voltage which is 5% higher
than the rated voltage. In North America, fuses are required
to clear only their rated voltage.
Accessories
Trip-indicator fuses are available for use in parallel with the
main fuse. Indicator fuses can be attached to the associated fuselink, or mounted separately in panel-mounted
fuseclips. In addition, a push-on adaptor and microswitch
attachment are available, to provide remote indication.
Fuseblocks are also available for most applications.

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,
E g , (RMS).
Arc Voltage
This curve gives the peak arc voltage,
U L , which may appear across the fuse
during its operation as a function of the
applied working voltage, E g , (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

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,
E g , (RMS).
1.6
Arc Voltage
This curve gives the peak arc voltage,
U L , which may appear across the fuse
during its operation as a function of the
applied working voltage, E g , (RMS) at a
power factor of 15%.

1.4
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, K p ,
is given as a function of the RMS load
current, Ib , in % of the rated current .

Select fuses designed and tested to:
• IEC 269: Part 4
• U.L. Recognized
Bussmann offers a full line of ferrule style (cylindrical and
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 660 volt — have been
tested at their rated voltage. The 660 volt ferrule fuse has
been tested to the IEC 269 standard, which requires
clearing at the rated voltage +10%.
Accessories
Ferrule fuses may be mounted in fuseclips, fuseholders,
fuseblocks or fused switches. A variety of products are
available to suit most end-use requirements.
