Features
• Coordinated communication concept using the PROFIBUS DP
or MODBUS, ranging from 16 A to 5000 A with SENTRON 3VL
and SENTRON 3WL5
• The high level of modularity of circuit breakers and accessories
allows easy retrofitting of all communication components
• Significant additional benefits for the switchboard due to the
possibility of linking up external input and output modules to
the circuit breaker-internal CubicleBUS of the SENTRON 3WL5
• Innovative software products for parameterization, operation,
monitoring, and diagnostics of SENTRON circuit breakers, both
locally or via PROFIBUS DP, MODBUS or Ethernet/Intranet/
Internet
Communication:
• For air circuit breakers with optional communication function
(ETU45B electronic trip units) see pages 4/7 and 4/8.
• For accessories see pages 4/17 and 4/18.
• For further information, see also Catalog LV 1 "Low-Voltage
Controls and Distribution – SIRIUS, SENTRON, SIVACON",

SENTRON 3WL5 Air Circuit Breakers/Non-Automatic Air Circuit Breakers
According to UL 489/IEC 60947-2 for AC up to 5000 A
General data
■ Benefits
■ Application
Low space requirements
The SENTRON 3WL5 devices require very little space. Size I
devices (up to 1600 A) fit into a 400 mm wide switchgear panel.
Size III devices (up to 5000 A) are the smallest of their kind and
with their construction width of 704 mm fit into a 800 mm wide
switchgear panel.
Modular design
Components like auxiliary trip units, motorized operating
mechanisms, electronic trip units, current sensors, auxiliary
circuit signaling switches, automatic reset devices, interlocks or
engagement operating mechanisms can all be exchanged or
retrofitted at a later stage, thus allowing the circuit breaker to be
adapted to new, changing requirements.
Retrofittable modules for electronic trip units
Modularity is one of the main features of the new SENTRON 3WL5
circuit breakers.
Special LCDs, ground-fault modules, rated current modules and
communication modules for the electronic trip units are available for
fast and easy retrofitting and adaptation to changing requirements.
Communication
4
The use of modern communication-capable circuit breakers
opens up completely new possibilities in terms of start-up,
parameterization, diagnostics, maintenance and operation.
This allows many different ways of reducing costs and improving
productivity in industrial plants, buildings and infrastructure
projects to be achieved.
• Timely information and response can prevent plant stoppages
• Effective diagnostics management
• Measured values are the basis for efficient load management,
for drawing up power demand profiles and for assigning energy
to cost centers
• Preventive maintenance reduces the risk of expansive plant
down-times
4/6
Siemens LV 16 · 2009
• As incoming-feeder, distribution, tie, and outgoing-feeder circuit breakers in electrical installations
• For switching and protecting motors, capacitors, generators,
transformers, busbars and cables
Due to the reinforced use of electronic I&C systems, the demands
made on air circuit breakers in terms of operator control and
monitoring of network processes have increased.
The extensive, coordinated SENTRON range of devices covers
all applications between 16 A and 5000 A with compact and air
circuit breakers.
Standards
SENTRON 3WL5 circuit breakers comply with:
• UL 489
• IEC 60947-2
• DIN VDE 0660 Part 101
• Climate-proof according to IEC 60068-2-30.

Overview of SENTRON 3WL5 circuit breakers/non-automatic air circuit
breakers
Versions
• Rated currents: 630 A to 5000 A
• 3 sizes for different rated current ranges (see illustration
"Overview of SENTRON 3WL5 Circuit Breakers/Non-Automatic
Air Circuit Breakers")
• 3-pole version,
4-pole version on request
• Rated operational voltage up to 600 V AC
• 2 different switching capacity classes in the range from 65 kA
to 100 kA at 480 V AC
The SENTRON 3WL5 circuit breakers are supplied complete
with operating mechanism (manual operating mechanism with
mechanical closing), electronic trip unit and auxiliary switches
(2 NO contacts + 2 NC contacts in the standard version), and
can be equipped with auxiliary trip units.
Installation types
Fixed-mounted or withdrawable version
Ambient temperatures
The SENTRON 3WL5 circuit breakers are climate-proof according
to IEC 60068-2-30. They are intended for use in enclosed areas
where no severe operating conditions (e.g. dust, corrosive vapors,
damaging gases) are present.
When installed in dusty and damp areas, suitable enclosures
must be provided.
Coordinated dimensions
The dimensions of SENTRON 3WL5 circuit breakers only differ in
terms of the width of the device which depends on the number
of poles and the size.
Due to the nature of the design, the dimensions of devices with
a withdrawable version are determined by the dimensions of the
guide frames, which are slightly larger.
Non-automatic air circuit breakers
One special version of circuit breaker is utilized as a non-automatic
air circuit breaker. The non-automatic air circuit breakers are
designed without an electronic trip unit system and do not
perform any protection functions for the system.
One potential application is the use as a bus coupler in systems
with parallel feed-ins.
The versions and features can be selected according to those of
the circuit breakers.
Operating mechanisms
The circuit breakers are available with various optional operating
mechanisms:
• Manual operating mechanism with mechanical closing
(standard design)
• Manual operating mechanism with mechanical and electrical
closing
• Motorized operating mechanism with mechanical and electrical
closing.
The operating mechanisms with electrical closing can be used
for synchronization tasks.

Connection options for auxiliary circuit connections
Auxiliary circuit connections
The type of connection for the auxiliary switches depends on the
type of installation:
• Withdrawable version: The internal auxiliary switches are
connected to the male connector on the switch side. When
fully inserted, the connector makes a connection with the
sliding contact module (see the graphic "Guide Frame" in
"Design") in the guide frame. Various adapters can then be
used to complete the wiring (see the graphic "Connection
options for auxiliary circuit connections").
• Fixed mounting: In this case the auxiliary supply connectors
are engaged directly onto the circuit breaker. The connectors
are equipped with coding pins that prevent them being
mistakenly interchanged.
Operator panel
The operator panel is designed to protrude from a cut-out in the
door providing access to all control elements and displays with
the control cabinet door closed.
The operator panels for all circuit breakers (fixed-mounted/
withdrawable versions, 3-/4-pole) are identical. The operator
panel ensures degree of protection IP41.

Other safety features include:
• Infeed from above or below, as required
• Locking of the guide frame with the circuit breaker removed,
as standard
• Locking of the withdrawable circuit breaker against movement,
as standard
• High degree of protection with cover (enclosure rating)
• Mechanical closing lockout after overload or short-circuit
tripping as standard
• The circuit breaker is always equipped with the required number
of auxiliary supply connectors

General data
Auxiliary trip units
Indicators, signals and control elements
Up to two auxiliary trip units can be installed at the same time.
The following are available:
Motor shutdown switch
1 shunt trip unit
or 1 undervoltage release
or 2 shunt trip units
or 1 shunt trip unit
+ 1 undervoltage release.
Signal switch for auxiliary trip units
One signaling contact is used for each auxiliary trip unit to determine
the switch positions of the auxiliary trip units.
Shunt trip unit
When the operational voltage is connected to the shunt trip unit,
the circuit breaker is opened immediately. The shunt trip unit is
available in the versions 5 % ON period for overexcitation and
100 % ON period for permanent excitation. This means that it is
also possible to block the circuit breaker against being jogged
into closing.
An energy storage device for shunt trip units allows the circuit
breaker to be opened even if the control voltage is no longer
available.
Undervoltage release
The undervoltage release causes the circuit breaker to be
opened if the operational voltage falls below a certain value or is
not applied. The circuit breaker cannot be closed manually or by
means of an electrical ON command if the undervoltage release
is not connected to the operational voltage. The undervoltage release has no delay as standard. A delay can be set by the
customer in the range between td < 80 ms and td < 200 ms.
In addition, an undervoltage release with a delay in the range
from 0.2 to 3.2 s is available.
Closing solenoid
The closing solenoid is used to close the circuit breaker electrically
by means of a local electrical ON command or by a remote unit.
Motorized operating mechanism
Control switch for switching off the motorized operating mechanism
(automatic loading).
Operating cycles counter
The motorized operating mechanism can be supplied with a 5-digit
operating cycles counter. The display is incremented by "1" as
soon as the spring energy store is fully loaded.
Resetting the manual tripped signal
When the circuit breaker has tripped, this is indicated by the
protruding red mechanical tripped indicator on the ETU. When
the mechanical tripped indicator is activated, the tripping solenoid
and tripped signal are reset. If this display is to be reset remotely,
the reset button can be equipped with a reset solenoid.
This option allows the circuit breaker to be reset both manually
and electrically.
Automatic resetting of closing lockout
When the ETU is activated, reclosing of the circuit breaker is
prevented until the trip unit is either electrically or manually reset.
If the "Automatic resetting of closing lockout" option is used, the
pre-tensioned circuit breaker is ready to close immediately after
tripping. Resetting the manual tripped indicator is not included
in this option.
Tripped signal switch
If the circuit breaker has tripped due to an overload, short-circuit,
ground fault or extended protection function, the tripped signal
switch can indicate this. This signal switch is available as an
option. If the circuit breaker is used for communication, this
option is supplied as standard.
Ready-to-close indicator switches
The SENTRON 3WL5 circuit breakers are equipped with an optical
ready-to-close indicator as standard. In addition, the ready-toclose status can be transmitted by means of a signal switch as
an option. If the switch is used for communication, the signal
switch is supplied as standard.
The operating mechanism is used to load the spring energy
store automatically.
The operating mechanism is activated if the spring energy store
has been unloaded and the control voltage is available.
It is switched off automatically after loading. This does not affect
manual operation of the stored-energy feature.

The electronic trip unit is controlled by a microprocessor and
operates independently of an auxiliary voltage. It enables
systems to be adapted to the different protection requirements
of distribution systems, motors, transformers and generators.
Communication capabilities
LCD alphanumeric
with 15°
inclination
and rotatable
through 180°
The international standard PROFIBUS DP or MODBUS can be
used to transmit data such as current values, switching states,
reasons for tripping etc. to central computers.
Data acquisition and energy management are possible in
conjunction with the Plus measurement function.

curve
A new internal circuit breaker data bus allows switchboard panel
communication between the circuit breaker and secondary
devices in the circuit breaker panel:
• Actuation of analog displays
• Facility to test the communication build-up with circuit breakers
• Display of tripping state and tripping reasons
• Input module for reading in further switchgear panel signals
and for transmission of these signals to the PROFIBUS DP or
MODBUS
• Various output modules for displaying measured values.
Rated current

This means that it is not only possible to monitor the device
remotely, but also to transmit current values from the entire
system and perform switching operations remotely.

(retrofittable)
I2t and I4t characteristic curve for overload protection
The best protection for the whole switchgear is achieved by
setting the tripping characteristic curve to an optimum value.
In order to achieve optimal discrimination for upstream fuses or
medium voltage protection systems, the inclination of the
characteristic curve can be selected for the overload range.
The overload protection L (long time protection) for the electronic
trip units ETU45B allows the characteristic curve to be switched
between I2t and I4t.
The I4t characteristic improves discrimination for downstream
circuit breakers and fuses.
Electronic trip units ETU
Modularity has also been strictly emphasized during the
development of the electronic trip units. These are some of the
modules which can be easily retrofitted at any time:
• Ground-fault protection module
• Communication
• Measurement function
• Display
• Rated current module (Rating Plug)
This allows quick adaptation to new local mains specifications.
In addition, innovative functions have been included in the ETUs.

Example of configuration for ETU45B
Rated current modules / Rating plugs
The rated current module is an exchangeable module which allows the user to reduce the rated device current so as to adapt
it optimally to the plant; e.g. if a new plant section is taken into
operation. The rated current module must be selected to fit the
rated current of the system.

Measurement method
Setting
Vectorial summation current formation (measurement method 1)
How the module is set depends on the measurement method
used (see above):
The three phase currents and the N-conductor current are
measured directly.
The electronic trip unit determines the ground-fault current by
means of vectorial summation current formation for the three
phase currents and the N conductor current.
A standard transformer with the following data is used for
measurement of the ground-fault current:
1200 A/1 A, Class 1 (the internal load of SENTRON 3WL5 is 0.11 ).
The transformer can be installed directly in the grounded neutral
point of a transformer.

Selection criteria for SENTRON 3WL circuit breakers
Basic criteria for selecting circuit breakers are:
• Max. short-circuit current at place of installation of circuit
breaker I k! max.
This value determines the short-circuit breaking capacity
or short-circuit current carrying capacity of the circuit breaker.
• It is compared with the value Icu, Ics, Icw of the circuit breaker
and essentially determines the size of the circuit breaker.
See illustration "Overview of SENTRON 3WL5 Circuit Breakers/
Non-Automatic Air Circuit Breakers".
• Rated current In which is to flow through the branch circuit.

General data
■ Configuration
Mutual mechanical circuit breaker interlocking
• The bending radii of the Bowden wire must be greater than
500 mm.
• The sum of all bending angles along the Bowden wire must not
exceed 640°.
• In a vertical arrangement of circuit breakers to be interlocked,
the interlocking mechanisms must be in line.
• Circuit breakers to be interlocked must be arranged so that
Bowden cables can be optimally installed in compliance with
the conditions mentioned in the above points.
• The installed Bowden cable must be fixed (with cable ties or
the like) before the interlock is adjusted.
• Select the width of switchgear cubicle to allow enough freedom
of movement for adjusting the interlock!
• Openings and cut-outs in system elements must be designed
so that Bowden cables are not changed in direction or
obstructed when they are passed through.
The module for mutual mechanical interlocking can be used for
one or two SENTRON 3WL5 circuit breakers and can be
adapted easily to the corresponding versions. The fixedmounted and withdrawable circuit breaker versions are fully
compatible and can therefore be used in a mixed configuration
in an installation.
The circuit breakers can be mounted alongside each other or
one above the other, whereby the distance of the circuit breakers
is determined solely by the length of the Bowden wire (lengths:
2 m/3 m/4.5 m). Interlock signals are looped through using the
Bowden cables. Interlocking is only effective in the connected
position in the case of withdrawable circuit breakers. The
mechanical endurance of the Bowden cables is 10000 operating
cycles.
Minimum requirements must be fulfilled in the switchgear for the
interlocking to function:
• Bowden cables must be installed as far as possible in a
straight line with minimum bending.

Communication with MODBUS
The requirements for power distribution in terms of communication
capability, data transparency, flexibility and integration are
constantly increasing. An integrated and modular communication
architecture was designed for the SENTRON 3WL5 to ensure
that it can satisfy these requirements.
The core component of this architecture is the CubicleBUS,
which links together all of the intelligent components within the
SENTRON 3WL5 and enables the easy and safe connection of
other additional external components to the circuit breaker. The
CubicleBUS is already incorporated and pre-connected in all
complete circuit breakers with ETU45B trip units.
The high level of modularity of the system allows communication
functions to be retrofitted at any time (e.g. the measurement
function). Similarly, the upgrade of a non-communication-capable
SENTRON 3WL5 (e.g. changeover from ETU25B to ETU45B with
CubicleBUS) can be carried out easily on site in the plant. All
modules connected to the CubicleBUS can directly access the
existing source data of the circuit breaker, which guarantees the
quickest possible access to information and response to events.
Furthermore, additional external modules (including digital inputs/
outputs, analog outputs) can be connected to the CubicleBUS
to provide cost-effective solutions for the automation of further
devices in the switchgear.

SENTRON 3WL5 Air Circuit Breakers/Non-Automatic Air Circuit Breakers
According to UL 489/IEC 60947-2 for AC up to 5000 A
General data
CubicleBUS modules
Digital output modules with rotary coding switch
6 items of binary information concerning the state of the circuit
breaker (reasons for tripping and warnings) can be output via
this module to external signaling devices (e.g. LED, horn) or be
used for the selective shut-down of other system components
(e.g. frequency converters).
Digital output modules are available in versions with and without
a rotary coding switch. On modules with a rotary coding switch
it is possible to choose between two signaling blocks each with
6 defined assignments and to set an additional response delay.
All the digital output modules are available as a version with
relay outputs (CO contacts, up to 12 A). Up to two modules of
this type can be connected to one SENTRON 3WL5.
Analog output module
Digital input modules
With the digital input module, up to 6 additional binary signals
(24 V DC) in the circuit breaker environment can be connected
to the system. It is thus possible to send messages concerning
the state of a switch disconnector or a control cabinet door to the
PROFIBUS DP or MODBUS.
One module each of this type can be used for holding the six
items of digital information and for automatically switching over
the parameters.
Digital output module with rotary coding switch
4
Digital output modules, configurable
The configurable output module is available for higher-performance
solutions. With this module, random events on the CubicleBUS
can be switched directly to one of six available outputs or three
of these outputs can be assigned with up to six events. In other
words, up to six events can be placed on one physical output
with OR operation. Either BDA/BDA Plus or Switch ES Power is
used for configuring.
A relay variant is also available here the same as for the output
modules with rotary coding switch. Only one module of this type
is possible per SENTRON 3WL5.
Digital input module
ZSI modules (short-time grading control)
The use of ZSI modules is recommended when Siemens circuit
breakers are arranged in several staggered levels but full grading
with the smallest possible delay is to be assured nevertheless.
The circuit breakers are interconnected by these modules. In
case of a short-circuit, each affected circuit breaker asks the
circuit breakers directly downstream whether the short-circuit
has also occurred in the next, lower level. The short-circuit is
exactly localized as the result, and only the next upstream circuit
breaker in the energy flow direction is switched off.
Digital output module, configurable
Analog output modules
The analog output module can be used to output the following
measured values to analog indicators in the control cabinet
door:
• IL1, IL2, IL3, IN or
• UL12, UL23, UL31, UL1N or
• PL1, PL2, PL3, Stot or
• p.f.1 , p.f.2 , p.f.3, I% or
• favg, ULLavg, Ptot, p.f.avg
Four 4-20-mA/0-10-V interfaces are available for this. The
measured values to be output are selected with a rotary coding
switch. By using the analog output module it is possible to do
without additional converters and their conventional installation/
wiring in the main current path. Up to two modules of this type
can be connected to one SENTRON 3WL5.

Every electronic trip unit type and every setting has its own
characteristic curve. Only a selection is shown in the following.
The characteristic curves each show the largest and smallest
setting range of SENTRON 3WL5 circuit breakers with 1000 A
rated current at 480 V rated voltage with various trip units. In
order to obtain a complete tripping characteristic, the relevant
parts of the characteristics have to be combined. The
characteristic curves show the behavior of the electronic trip unit
when it is activated by a current that is already flowing before the
tripping operation. If the overcurrent tripping occurs immediately
after switch on and the electronic trip unit is therefore not yet
enabled, the opening time is extended, depending on the level
of the overcurrent by up to 15 ms. In order to determine the
break-times of the circuit breakers, approximately 15 ms must
be added to the opening times shown for the arcing time.
Refer to the following legend for tolerances.
The characteristic curves shown apply to ambient temperatures
at the circuit breaker between -5 and +55 °C. The trip unit can
be operated at ambient temperatures of -20 to +70 °C. An
extended tolerance band can apply at these temperatures.
