Overview of 3WL circuit breakers/non-automatic air circuit breakers
Coordinated dimensions
Versions
The dimensions of 3WL circuit breakers only differ in terms of the
width of the device which depends on the number of poles and
the size.
• Rated currents: 630 A to 6300 A
• 3 sizes for different rated current ranges (see above illustration)
• 3 and 4-pole versions
• Rated operational voltage up to 690 V AC and 1000 V DC.
Special versions up to 1000 V AC and 1150 V AC available
• 4 different switching capacity classes in the range from 55 kA
to 150 kA for AC applications and one switching capacity
class for DC applications.
The 3WL circuit breakers are supplied complete with operating
mechanism (manual operating mechanism with mechanical
closing), electronic release and auxiliary switches (2 NO contacts + 2 NC contacts in the standard version), and can be
equipped with auxiliary releases.
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 release system and do not
perform any protection function 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.
Installation types
Operating mechanisms
Fixed-mounted or withdrawable version
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
Ambient temperatures
The 3WL 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.
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
installation type:
• 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 cutout in the
door providing access to all control elements and displays with
the control cabinet door closed.

General data
Withdrawable short-circuit, grounding, and bridging units
Portable positively-driven grounding and short-circuit devices
are used for the disconnected system sections to verify isolation
from the supply at the workplace.
Withdrawable grounding units allow simple and comfortable
grounding. They are simply inserted into the guide frames in
place of the corresponding withdrawable circuit breakers. This
ensures that these devices are always first connected with the
grounding electrode and then with the components to be
grounded.
The grounding contacts are fitted to the side of the switch enclosure and establish the connection when inserted into the guide
frame.
An energy storage device for shunt releases 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.

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
All withdrawable terminals are short-circuited and grounded on
delivery.
The operating mechanism is used to load the storage spring automatically.
They are easily converted into withdrawable bridging units by
qualified electricians according to the enclosed instructions.
The operating mechanism is activated if the storage spring has
been unloaded and the control voltage is available.
In addition, the withdrawable unit can be adapted to various
rated currents of a size.
It is switched off automatically after loading. This does not affect
manual operation of the storage spring.
Withdrawable short-circuit and grounding unit
Indicators, signals, and control elements
The withdrawable short-circuit and grounding unit consists of a
breaker enclosure with penetration blades which are connected
with the short-circuiting link.
Motor shutdown switch
Depending on the version, the short-circuiting links are arranged
at the top and/or bottom. The grounding and short-circuit connections are established when the device is inserted.
It must be ensured that the side to be short-circuited and
grounded is not live. For this reason it is recommended that the
withdrawable unit is only wound in when the door is closed.
Withdrawable bridging unit
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 storage spring is fully loaded.
Resetting the manual tripped signal
The withdrawable bridging unit consists of a breaker enclosure
in which all disconnection components and the operating mechanism have been replaced with simple connections between the
upper and lower contacts.
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.
Auxiliary releases
This option allows the circuit breaker to be reset both manually
and electrically.
Up to two auxiliary releases can be installed at the same time.
The following are available:
Automatic resetting of reclosing lockout
1 shunt release
or 1 undervoltage release
or 2 shunt releases
or 1 shunt release
+ 1 undervoltage release.
When the ETU is activated, reclosing of the circuit breaker is prevented until the release is either electrically or manually reset. If
the "Automatic resetting of reclosing 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.
Signaling switch for auxiliary releases
Tripped signaling switch
One signaling contact is used for each auxiliary release to determine the switch positions of the auxiliary releases.
If the circuit breaker has tripped due to an overload, short-circuit, ground fault or extended protection function, the tripped
signaling switch can indicate this. This signaling switch is available as an option. If the circuit breaker is used for communication, this option is supplied as standard.
Shunt release
When the operational voltage is connected to the shunt release,
the circuit breaker is opened immediately. The shunt release is
available in the versions 5 % OP for over-excitation
and 100 % OP for permanent excitation. This means that it is also
possible to block the circuit breaker against being jogged into
closing.

Ready-to-close signaling switches
The 3WL circuit breakers are equipped with an optical ready-toclose indicator as standard. In addition, the ready-to-close status can be transmitted by means of a signaling switch as an option. If the switch is used for communication, the signaling switch
is supplied as standard.

Electronic releases (ETU)
The electronic release 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.

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.
A new internal circuit breaker data bus allows switchboard panel
communication between the circuit breaker and secondary devices in the circuit breaker section:
• 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.

module (retrofittable)
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.
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.
Example of configuration for ETU45B
The overload protection L (long time protection) for the electronic releases ETU45B and ETU76B allows the characteristic
curve to be switched between I2t and I4t.
The I4t characteristic improves discrimination for downstream
circuit breakers and fuses.
Electronic releases ETU
Modularity has also been strictly emphasized during the development of the electronic releases. 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.
Rated current module/Rating Plug
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 plant.

Selectable parameters
In the case of quick changes of power supply conditions,
e. g. for switchovers from transformer to generator operation or
if a section of the supply is disconnected when the shift
changes, the 3WL circuit breaker allows the relevant protection
parameters to be quickly adapted to the new conditions.
The ETU76B contains two independent tripping characteristic
curves (parameter sets). The switchover is completed within
200 ms and is performed with the help of an external signal.

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.
Measurement method 1: in position
.
The electronic release determines the ground-fault current by
means of vectorial summation current formation for the three
phase currents and the N conductor current.
Measurement method 2: in position
.
Direct measurement of the ground-fault current (measurement
method 2)
Ground-fault protection with I2t characteristic curve
A standard current transformer with the following data is used for
measurement of the ground-fault current:
1200 A/1 A, Class 1 (the internal load of the 3WL circuit breaker
is 0.11 Ω). The current transformer can be installed directly in the
grounded neutral point of a transformer.
With the exception of the ETU27B electronic release, all
versions of the ground-fault modules are supplied with an I2t
characteristic curve which can be activated.

This setting can be implemented for the electronic release version ETU76B with Menu/Comm.
Selection criteria for 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 3WL Circuit Breakers/Non-Automatic Air Circuit Breakers".
• Rated current In which is to flow through the branch circuit.
This value must not be greater than the maximum rated circuit
breaker current of the circuit breaker.
The rated current for the 3WL circuit breaker is specified using
the rated current module. See illustration "Overview of 3WL
Circuit Breakers/Non-Automatic Air Circuit Breakers" in "Design".
• Ambient temperature
for the circuit breaker.
This is usually the control cabinet internal temperature.
• Design of the circuit breaker
• Minimum short-circuit current
which flows through the switching device. The release must
still detect this value as a short-circuit and must respond by
tripping.
Protection functions of the circuit breaker.
These are determined by the selection of the
corresponding electronic release, see the table
"Functions of the Electronic Releases" under "Functions".

This version of the 3WL non-automatic air circuit breaker is suitable for direct current applications. The external protective device DIGmat S100 provides adjustable overload and short-circuit protection for 3WL non-automatic air circuit breakers.
This is based on the measuring chain of a shunt resistor and the
DIGmat S100 tripping unit. Shunt resistors are available for
1000 A, 2000 A and 4000 A (special ranges on request).
They are in accordance with DIN 43703 and have a class
accuracy of 0.5.
A measuring-circuit voltage of 60 mV DC is picked off for rated
current In.
The measuring-circuit voltage is a linear image of the primary
current.
DIGmat S100
The DIGmat S100 tripping unit monitors the image of the primary
current thus supplied and compares it with the tripping characteristic curve set on the device. The parameter settings on the
DIGmat S100 apply also for DC feedbacks.
Reversing duty is possible therefore.
• Short-circuit protection:
Setting range Ii = 1.25 × IR up to max. 4 × In
If the set value is exceeded, tripping occurs in less than
50 ms.
The tripping characteristic curve is determined and described
by the following
variables:
• Overload protection:
Setting range IR = 0.4 ... 1.0 In
The characteristic curve has an I2t characteristic.
The tripping time tR can be selected between 2 and 10 s,
although tR for 6 × IR is defined.

■ Configuration
• The bending radii of the Bowden wire must be > 500 mm.
• The sum of all bending angles along the Bowden cable 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.
Mutual mechanical circuit breaker interlocking
The module for mutual mechanical interlocking can be used for
one or two 3WL circuit breakers and can be adapted easily to
the corresponding versions. The fixed-mounted and withdrawable circuit breaker versions are fully compatible and can therefore be used in a mixed configuration in an installation. This also
applies to 3WN6 circuit breakers.
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 3WL circuit breaker 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
3WL circuit breaker 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 and ETU76B releases.
20
Siemens · 2012
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 3WL circuit breaker (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.

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. light, 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 3WL circuit breaker.
Analog output 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 for example to send messages
concerning the state of a switch disconnector or a control cabinet door to the PROFIBUS DP/MODBUS.
With the digital input module on the CubicleBUS it is also possible for the two different protection parameter sets held in the
ETU76B electronic releases to be switched over automatically in
a few milliseconds. It is thus possible, for example, to automatically change the parameters of a coupling switch should the
transformer infeed fail.
Digital output modules with rotary coding switch
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 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 3WL circuit breaker.
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.
Digital output modules, configurable
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.
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, ΔI % 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 3WL circuit breaker.

Every release 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
3WL circuit breakers with 1000 A rated current at 500 V rated
voltage with various releases. 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 release 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 release 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 release can
be operated at ambient temperatures of -20 to +70°C.
An extended tolerance band can apply at these temperatures.

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 release 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 release 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 total break-times
of the circuit breakers, approximately 15 ms must be added to
the opening times shown for the arcing time.

of 1 m from the connecting bars, the circuit breaker can be used
at full operational current load.
If the parallel or series connections are made directly at the
connecting bars, for thermal reasons the continuous load on the
circuit breakers must only be 80 % of the permissible operational
