Introduction
Fuse Systems
Overview
Rated voltage Un
The rated voltage is the designated voltage of the fuse and is
used to determine its test conditions and operational voltage
limits.
For LV HRC and SITOR fuse links, the rated voltage is always the
rms value of an AC voltage.
For wind power plants and some industrial applications, a higher
voltage tolerance is demanded of the LV HRC and SITOR fuses
than the tolerance of +5 % defined in the standard. On request,
you can obtain a manufacturer's declaration for the rated voltage
of 690 V +10 %.
In the case of NEOZED and DIAZED fuse links, a distinction is
made between AC and DC voltage values.
Rated current In
The rated current of a fuse link is the designated current of the
fuse link and is the current up to which it can be continuously
loaded under prescribed conditions without adverse affects.
Rated frequency
The rated frequency is the frequency for which the fuse link
is rated with regard to power dissipation, current, voltage,
characteristic curve and breaking capacity.
Selectivity
Several fuses are usually connected in series in a system. Selec-
tivity ensures that only the faulty electric circuit and not all oper-
ating processes are interrupted in a system in serious cases.
Siemens fuses of operational class gG, at an operational voltage
of up to 400 V AC and a ratio of 1:1.25, are interselective, i.e.
from rated current level to rated current level. This is achieved by
means of the considerably smaller band of scatter of ± 5 % of
the time/current characteristics, which far exceeds the demand
for a ratio of 1:1.6 specified in the standard.
It is therefore possible to use smaller conductor cross-sections
due to the lower rated currents.
Breaking capacity
The rated breaking capacity is the highest prospective short-
circuit current Ip that the fuse link can blow under prescribed
conditions.
A key feature of these fuses is their high rated breaking capacity
with the smallest footprint. The basic demands and circuit data
for tests – voltage, power factor, actuating angle, etc. – are
specified in both national (DIN VDE 0636) and international
(IEC 60269) regulations.
However, for a constant fail-safe breaking capacity, from the
smallest non-permissible overload current through to the highest
short-circuit current, a number of quality characteristics need to
be taken into account when designing and manufacturing fuse
links. These include the design of the fuse element with regard
to dimensions and punch dimension and its position in the
fuse body, as well as its compressive strength and the thermal
resistance of the body. The chemical purity, particle size and
the density of the quartz sand also play a key role.
The rated breaking capacity for AC voltage for NEOZED fuses
and the majority of DIAZED fuses – is 50 kA, and in the case of
our LV HRC fuses (NH type), it is even 120 kA. The various type
ranges of SITOR semiconductor fuses have different switching
capacities ranging from 50 to 100 kA.
.
Faster arcing and precise arc quenching are the requirements for a
reliable breaking capacity.
Operational classes
Fuses are categorized according to function and operational
classes. The first letter defines the function class and the second
the object to be protected:
1st letter
a = Partial range protection
(accompanied fuses):
Fuse links that carry currents at least up to their specified rated
current and can switch currents above a specific multiple of their
rated current up to their rated breaking current.
g = Full range protection
(general purpose fuses):
Fuse links that can continuously carry currents up to at least their
specified rated current and can switch currents from the small-
est melting current through to the breaking current. Overload
and short-circuit protection.
2nd letter
G = Cable and line protection
(general applications)
M = Switching device protection in motor circuits
(for protection of motor circuits)
R, S = Semiconductor protection/thyristor protection
(for protection of rectifiers)
L = Cable and line protection
(in acc. with the old, no longer valid DIN VDE)
B = Mine equipment protection
Tr = Transformer protection
The designations "slow" and "quick" still apply to DIAZED fuses.
These are defined in IEC/CEE/DIN VDE.
In the case of "quick" characteristics, the fuse blows in the break-
ing range faster than those of operational class gG.
In the case of DIAZED fuse links for DC railway network protec-
tion, the "slow" characteristic is particularly suitable for switching
off direct currents with greater inductance. Both characteristics
are also suitable for the protection of cables and lines.
Full range fuses (gG, gR, quick, slow) reliably break the
current in the event of non-permissible overload and short-
circuit currents.
Partial range fuses (aM, aR) exclusively serve short-circuit
protection.

The following operational classes are included in the product
range:
gG (DIN VDE/IEC) = Full-range cable and line protection
aM (DIN VDE/IEC) = Partial-range switching device
protection
aR (DIN VDE/IEC) = Partial-range semiconductor protection
gR (DIN VDE/IEC) = Full-range semiconductor protection
gS (DIN VDE/IEC) = Full-range semiconductor protection
and cable and line protection
quick (DIN VDE/IEC/CEE) = Full-range cable and
line protection
slow (DIN VDE) = Full range cable and line protection
Characteristic curves (time/current characteristic curves)
The time/current characteristic curve specifies the virtual time
(e.g. the melting time) as a function of the prospective current
under specific operating conditions.
Melting times of fuse links are presented in the time/current
diagrams with logarithmic subdivision as a function of their cur-
rents. The melting time characteristic curve extends from the
lowest melting current, which still just causes the melting con-
ductor to melt asymptotically to the I2t line of equal Joulean heat
values in the range of higher short-circuit currents, which speci-
fies the constant melting heat value I2t. For the sake of simplicity,
the time/current characteristics diagrams omit the I2t lines (c).
General representation of the time/current characteristic curve of a fuse
link of operational class gL/gG
Imin: Smallest melting current
a: Melting time/current characteristic
b: Breaking time characteristic curve
c: I2t line
The curve of the characteristic depends on the outward heat
transfer from the fuse element. DIN VDE 0636 specifies toler-
ance-dependent time/current ranges within which the character-
istic curves of the fuse must lie. Deviations of ± 10 % are permis-
sible in the direction of the current axis. With Siemens LV HRC
fuse links of operational class gG, the deviations work out at
less than ± 5 %, a mark of our outstanding production accuracy.
For currents up to approx. 20 In, the melting time/current charac-
teristic curves are the same as the breaking time characteristic
curves. In the case of higher short-circuit currents, the two
characteristic curves move apart, influenced by the respective
arc quenching time.
The difference between both lines (= arc quenching time) also
depends on the power factor, the operational voltage and the
breaking current.
The Siemens characteristic curves show the mean virtual melt-
ing time characteristic curves recorded at an ambient tempera-
ture of (20 ± 5) °C. They do not apply to preloaded fuse links.
Virtual time tv
The virtual time is the time span calculated when an I2t value is
divided by the square of the prospective current:
The time/current characteristic curve specifies the prospective
current Ip and the virtual melting time tvs.
Prospective short-circuit current Ip
The prospective short-circuit current is the rms value of the
line-frequency AC component, or the value of direct current to
be expected in the event of a short-circuit occurring downstream
of the fuse, were the fuse to be replaced by a component of
negligible impedance.
Let-through current characteristic curves
The let-through current characteristic curve specifies the value
of the let-through current at 50 Hz as a function of the prospec-
tive current.
The let-through current Ic is the maximum instantaneous value
of the current reached during a switching operation of a fuse.
The fuse element of the fuse links melts so quickly at very high
currents that the surge short-circuit current Ip is prevented from
occurring. The highest instantaneous value of the current
reached during the breaking cycle is called the let-through
current Ic. The current limits are specified in the current limiting
diagrams, otherwise known as let-through current diagrams.

Introduction
Fuse Systems
Current limiting
As well as a fail-safe rated breaking capacity, the current-limiting
effect of a fuse link is of key importance for the cost effectiveness
of a system. In the event of short-circuit breaking by a fuse, the
short-circuit current continues to flow through the network until
the fuse link is switched off. However, the short-circuit current
is only limited by the system impedance.
The simultaneous melting of all the bottlenecks of a fuse element
produce a sequence of tiny partial arcs that ensure a fast break-
ing operation with strong current limiting. The current limitation is
also strongly influenced by the production quality of the fuse –
which in the case of Siemens fuses is extremely high. For exam-
ple, an LV HRC fuse link, size 2 (224 A) limits a short-circuit cur-
rent with a possible rms value of approximately 50 kA to a let-
through current with a peak value of approx. 18 kA. This strong
current limitation provides constant protection for the system
against excessive loads.

Rated power dissipation
Rated power dissipation is the power loss during the load of
a fuse link with its rated current under prescribed conditions.
The cost effectiveness of a fuse depends largely on the rated
power dissipation (power loss). This should be as low as possi-
ble and have low self-heating. However, when assessing the
power loss of a fuse, it must also be taken into account that there
is a physical dependence between the rated breaking capacity
and the rated power dissipation. On the one hand, fuse elements
need to be very thick in order to achieve the lowest possible
resistance value, on the other, a high rated breaking capacity
requires the thinnest possible fuse elements in order to achieve
reliable arc quenching.
Siemens fuses have the lowest possible rated power dissi-
pation while also providing the highest possible load breaking
reliability.
These values lie far below the limit values specified in the r
egulations. This means a low temperature rise, reliable breaking
capacity and high cost effectiveness.
I2t value
The I2t value (joule integral) is the integral of the current squared
over a specific time interval:
Specifies the I2t values for the melting process (I2ts) and for
the breaking cycle ((I2tA, , – sum of melting and quenching
I2t value). The melting I2t value, also known as the total I2t value
or breaking I2t value, is particularly important when dimension-
ing SITOR semiconductor fuses. This value depends on the
voltage and is specified with the rated voltage.
Peak arc voltage Ûs
The peak arc voltage is the maximum value of the voltage
that occurs at the connections of the fuse link during the arc
quenching time.
Residual value factor RV
The residual value factor is a reduction factor for determining the
permissible load period of the fuse link with currents that exceed
the permissible load current In (see rated current In). This factor
is applied when dimensioning SITOR semiconductor fuses.
Varying load factor VL
The varying load factor is a reduction factor for the rated current
with varying load states. This factor is applied when dimension-
ing SITOR semiconductor fuses.
Recovery voltage Uw
The recovery voltage (rms value) is the voltage that occurs at the
connections of a fuse link after the power is cut off.

Load capability with increased ambient temperature
The time/current characteristic curve of the NEOZED/DIAZED
and LV HRC fuse links is based on an ambient temperature of
20 °C ± 5 °C in accordance with DIN VDE 0636. When used in
higher ambient temperatures (see diagram) a reduced load-car-
rying capacity must be planned for. At an ambient temperature
of 50 °C, for example, an LV HRC fuse link should be dimen-
sioned for only 90 % of the rated current. While the short-circuit
behavior is not influenced by an increased ambient temperature,
it is influenced by overload and operation at rated value.
Influence of the ambient temperature on the load capability of
NEOZED/DIAZED and LV HRC fuses of operational class gG with
natural convection in the distribution board.
Assignment of cable and line protection
When gG fuses are assigned for cable and line protection
against overloading, the following conditions must be met in
order to comply with DIN VDE 0100 Part 430:
(1) IB = In = Iz (rated current rule)
(2) I2 = 1.45 × Iz (tripping rule)
IB: Operational current of electrical circuit
In: Rated current of selected protective device
Iz: Permissible current carrying capacity of the cable or line
under specified operating conditions
I2: Tripping current of the protective device under specified
operating conditions ("high test current").
These days, the factor 1.45 has become an internationally
accepted compromise of the protection and utilization ratio of a
line, taking into account the breaking response of the protective
device (e.g. fuse).
In compliance with the supplementary requirements for
DIN VDE 0636, Siemens fuse links of operational class gG
comply with the following condition:
"Load breaking switching with I2=1.45 × In during conventional
test duration under special test conditions in accordance with
the aforementioned supplementary requirements of
DIN VDE 0636".
This therefore permits direct assignment.

Fuse Systems
NEOZED Fuse Systems
Overview
The NEOZED fuse system is primarily used in distribution tech-
nology and industrial switchgear assemblies. The system is easy
to use and is also approved for domestic installation.
The MINIZED switch disconnectors are primarily used in switch-
gear assemblies and control engineering. They are approved for
switching loads as well as for safe switching in the event of short
circuits. The MINIZED D02 is also suitable for use upstream of
the meter in household applications in compliance with the
recommendations of VDEW according to TAB 2007.
Due to its compact design, the MINIZED D01 fuse switch
disconnector is primarily used in control engineering.
The NEOZED fuse bases are the most cost-effective solution for
using NEOZED fuses. All NEOZED bases must be fed from the
bottom to ensure that the threaded ring is insulated during re-
moval of the fuse link. The terminals of the NEOZED bases are
available in different versions and designs to support the various
installation methods.

Fuse Systems
DIAZED fuse systems
Overview
The DIAZED fuse system is one of the oldest fuse systems in
the world. It was developed by Siemens as far back as 1906.
It is still the standard fuse system in many countries to this day.
It is particularly widely used in the harsh environments of indus-
trial applications.
The series is available with rated voltages from 500 V to 750 V.
All DIAZED bases must be fed from the bottom to ensure an
insulated threaded ring when the fuse link is being removed.
Reliable contact of the fuse links is only ensured when used
together with DIAZED screw adapters.
The terminals of the DIAZED bases are available in different ver-
sions and designs to support the various installation methods.
The high-performing EZR bus-mounting system for screw fixing
is an outstanding feature. The busbars, which are particularly
suited for bus-mounting bases, have a load capacity of up to
150 A with lateral infeed.
DIAZED stands for Diametral gestuftes zweiteiliges Sicherungs-
system mit Edisongewinde (diametral two-step fuse system with
Edison screw).

Cylindrical fuse links and cylindrical fuse holders
Fuse Systems
Cylindrical Fuse Systems
Overview
Cylindrical fuses are standard in Europe. There are a range of
different cylindrical fuse links and holders that comply with the
standards IEC 60269-1, -2 and -3, and which are suitable for use
in industrial applications. In South West Europe they are also
approved for use in residential buildings.
The cylindrical fuse holders are also approved according to
UL 512. The cylindrical fuse holders are tested and approved as
fuse disconnectors according to the switching device standard
IEC 60947-3. They are not suitable for switching loads.
Cylindrical fuse holders can be supplied with or without signal
detectors. In the case of devices with signal detector, a small
electronic device with LED is located behind an inspection
window in the plug-in module. If the inserted fuse link is tripped,
this is indicated by the LED flashing.
The switching state of the fuse holder can be signaled over a
laterally retrofitted auxiliary switch, which enables the integration
of the fuses in the automation process.
Benefits
Devices with pole number 1P+N are available in a single
modular width. This reduces the footprint by 50 %
The sliding catch for type ranges 8 x 32 mm and 10 x 38 mm
enables the removal of individual devices from the assembly
Space for a spare fuse in the plug-in module enables the
fast replacement of fuses. This saves time and money and
increases system availability
A flashing LED signals that a fuse link has been tripped.
This enables fast detection during runtime
Technical specifications
1) Degree of protection IP20 is tested according to regulations using a
straight test finger (from the front), with the device mounted and equipped
with a cover, housing or some other enclosure.
2) Max. cross-section 10 mm2 with K28 crimper from Klauke.

Fuse holders in size 10 x 38 mm and Class CC
Fuse Systems
Cylindrical Fuse Systems
Overview
A key feature of our three-pole fuse holders is their ultra compact
design. With a width of only 45 mm, they are ideal for use with
fused motor starter combinations. Because the contactor and
the fuse holder have the same 45 mm width, they are easy to
mount on top of one another. The strong current-limiting fuses
ensure a type 2 protection level (coordination according to
IEC 60947-4, no damage protection) for the contactor.
The UL version has an SCCR value of 200 kA. The accessories
are generally UL-certified.
Customers can mount an auxiliary switch which signals the
switching state or prevents the fuse holder from switching off
under load by interrupting the contactor control, thus increasing
safety for the operator and process. Busbars and a matching
three-phase feeder terminal complete the product range.
Benefits
Compact design, especially for motor starter combinations
For IEC fuses of size 10 x 38 mm up to 32 A and Class CC

Class CC fuse systems
Fuse Systems
Overview
Class CC fuses are used for "branch circuit protection".
The enclosed fuse holders are designed and tested to comply
with the US National Electrical Code NEC 210.20(A). This means
that when subject to continuous operation, only 80 % of the rated
current is permissible as operational current.
An operational current of 100 % of the rated current (30 A) is only
permissible short-time.
The devices are prepared for the inscription labels of the
ALPHA FIX terminal blocks 8WH8120-7AA15 and
8WH8120-7XA05.
There are three different series:
Characteristic: slow 3NW1...-0HG
For the protection of control transformers, reactors, induc-
tances. Significantly slower than the minimum requirements
specified by UL for Class CC Fuses of 12 s at 2 × In.
Characteristic: quick 3NW2...-0HG
For a wide range of applications, for the protection of lighting
installations, heating, control systems.
Characteristic: slow, current-limiting 3NW3...-0HG
Slow for overloads and quick for short circuits. High current
limitation for the protection of motor circuits.
Note:
For class CC compact fuse holders for motor starter combina-
tions, see page 32.
Benefits
For switchgear assemblies and machine manufacturers
who export their systems to the USA or Canada
Easier export due to UL and CSA approvals for typical
applications
Modern design with touch protection to BGV A3 ensures
safe installation.

LV HRC fuse links
Overview
LV HRC fuse systems (NH type) are used for installation systems
in non-residential, commercial and industrial buildings as well as
in switchgear assemblies of power utilities. They therefore pro-
tect essential building parts and systems.
LV HRC fuse systems (NH type) are fuse systems designed for
operation by experts. There are no constructional requirements
for non-interchangeability of rated current and touch protection.
The components and auxiliary equipment are designed in such
a way as to ensure the safe replacement of LV HRC fuse systems
or isolation of systems.
LV HRC fuse links are available in the sizes 000, 00, 0, 1, 2, 3, 4
and 4a.
LV HRC fuse links are available in the following operational
classes:
gG for cable and line protection
aM for short-circuit protection of switching devices in motor
circuits
gR or aR for protection of power semiconductors
gS: The new gS operational class combines cable and line
protection with semiconductor protection
LV HRC fuse links of size 000 can also be used in LV HRC fuse
bases, LV HRC fuse switch disconnectors, LV HRC fuse strips as
well as LV HRC in-line fuse switch disconnectors of size 00.
The fuse links 300 A, 355 A and 425 A comply with the standard
but do not have the VDE mark.
