3RW Soft Starters
3RW30
for standard applications
■ Overview
The SIRIUS 3RW30 soft starters reduce the motor voltage
through variable phase control and increase it in ramp-like mode
from a selectable starting voltage up to mains voltage. During
starting, these devices limit the torque as well as the current and
prevent the shocks which arise during direct starts or wye-delta
starts. In this way, mechanical loads and mains voltage dips can
be reliably reduced.
Soft starting reduces the stress on the connected equipment
and results in lower wear and therefore longer periods of troublefree production. The selectable start value means that the soft
starters can be adjusted individually to the requirements of the
application in question and unlike wye-delta starters are not
restricted to two-stage starting with fixed voltage ratios.
The SIRIUS 3RW30 soft starters are characterized above all by
their small space requirements. Integrated bypass contacts
mean that no power loss has to be taken into the bargain at the
power semiconductors (thyristors) after the motor has started
up. This cuts down on heat losses, enabling a more compact
design and making external bypass circuits superfluous.
■ Application
The 3RW30 soft starters are suitable for soft starting of threephase asynchronous motors.
Due to two-phase control, the current is kept at minimum values
in all three phases throughout the entire starting time. Due
to continuous voltage influencing, current and torque peaks,
which are unavoidable in the case of wye-delta starters, for
instance, do not occur.
Application areas
• Pumps
• Heat pumps
• Hydraulic pumps
• Presses
• Conveyors
• Roller conveyors
• Screw conveyors
Various versions of the SIRIUS 3RW30 soft starters are available:
• Standard version for fixed-speed three-phase motors, sizes
S00, S0, S2 and S3, with integrated bypass contact system
• Version for fixed-speed three-phase motors in a 22.5 mm
enclosure without bypass
6
Soft starters rated up to 55 kW (at 400 V) for standard
applications in three-phase networks are available. Extremely
small sizes, low power losses and simple start-up are just three
of the many advantages of this soft starter.

3RW40
for standard applications
■ Overview
■ Application
SIRIUS 3RW40 soft starters have all the same advantages as the
3RW30 soft starters.
The SIRIUS 3RW40 soft starters are characterized above all by
their small space requirements. Integrated bypass contacts
mean that no power loss has to be taken into the bargain at the
power semiconductors (thyristors) after the motor has started
up. This cuts down on heat losses, enabling a more compact
design and making external bypass circuits superfluous.
At the same time this soft starter comes with additional
integrated functions such as adjustable current limiting, motor
overload and intrinsic device protection, and optional thermistor
motor protection. The higher the motor rating, the more
important these functions because they make it unnecessary to
purchase and install protection equipment such as overload
relays.
Internal intrinsic device protection prevents the thermal
overloading of the thyristors and the power section defects this
can cause. As an option the thyristors can also be protected by
semiconductor fuses from short-circuiting.
Thanks to integrated status monitoring and fault monitoring, this
compact soft starter offers many different diagnostics options.
Up to four LEDs and relay outputs permit differentiated
monitoring and diagnosis of the operating mechanism by
indicating the operating state as well as for example mains or
phase failure, missing load, non-permissible tripping time/class
setting, thermal overloading or device faults.
Soft starters rated up to 250 kW (at 400 V) for standard
applications in three-phase networks are available. Extremely
small sizes, low power losses and simple start-up are just three
of the many advantages of the SIRIUS 3RW40 soft starters.

"Increased safety" type of protection EEx e according to
ATEX directive 94/9/EC
The 3RW40 soft starters size S6, S10 and S12 are suitable for
starting explosion-proof motors with "increased safety" type of
protection EEx e;
see Catalog LV 1 "Appendix" –> "Standards and approvals" –>
"Type overview of approved devices for explosion-protected
areas (ATEX explosion protection)".
6/6
Siemens LV 1 N SIRIUS Soft Starters · 01/2008
The SIRIUS 3RW40 solid-state soft starters are suitable for soft
starting and stopping of three-phase asynchronous motors.
Due to two-phase control, the current is kept at minimum values
in all three phases throughout the entire starting time and
disturbing direct current components are eliminated in addition.
This not only enables the two-phase starting of motors up to
250 kW (at 400 V) but also avoids the current and torque peaks
which occur e.g. with wye-delta starters.

Selection of the soft starter depends on the rated motor current.
The SIRIUS 3RW40 solid-state soft starters are designed for
easy starting conditions. JLoad < 10 x JMotor . In the event of
deviating conditions or increased switching frequency, it may be
necessary to choose a larger device. Siemens recommends the
use of the selection and simulation program Win-Soft Starter.

3RW30
for standard applications
■ Function
The space required by the compact SIRIUS 3RW30 soft starter
is often only about one third of that required by a wye-delta
assembly of comparable rating. This not only saves space in the
control cabinet and on the standard mounting rail but also does
away completely with the wiring work needed for wye-delta
starters. This is notable in particular for higher motor ratings
which are only rarely available as fully wired solutions.
At the same time the number of cables from the starter to the
motor is reduced from six to three. Compact dimensions, short
start-up times, easy wiring and fast commissioning make
themselves felt as clear-cut cost advantages.
The bypass contacts of these soft starters are protected during
operation by an integrated solid-state arc quenching system.
This prevents damage to the bypass contacts in the event of a
fault, e.g. brief disconnection of the control voltage, mechanical
shocks or life-related component defects on the coil operating
mechanism or main contact spring.
The new series of devices comes with the "polarity balancing"
control method, which is designed to prevent direct current
components in two-phase controlled soft starters. On two-phase
controlled soft starters the current resulting from superimposition
of the two controlled phases flows in the uncontrolled phase.
This results for physical reasons in an asymmetric distribution of
the three phase currents during the motor ramp-up. This
phenomenon cannot be influenced, but in most applications it is
non-critical.
It creates a motor ramp-up that is uniform in speed, torque and
current rise, thus permitting a particularly gentle, two-phase
starting of the motors. At the same time the acoustic quality of
the starting operation comes close to the quality of a threephase controlled soft starter. This is made possible by the ongoing dynamic harmonizing and balancing of current half-waves
of different polarity during the motor ramp-up. Hence the name
"polarity balancing".
• Soft starting with voltage ramp; the starting voltage setting
range Us is 40 % to 100 % and the ramp time tR can be set
from 0 s to 20 s.
• Integrated bypass contact system to minimize power loss
• Setting with two potentiometers
• Simple mounting and start-up
• Mains voltages at 50/60 Hz, 200 to 480 V
• Two control voltage versions 24 V AC/DC and 110 to 230 V AC/DC
• Wide temperature range from -25 °C to +60 °C
• The built-in auxiliary contact ensures user-friendly control and
possible further processing within the system (for status
graphs see page 6/22).
6
Controlling the power semiconductors results not only in this
asymmetry, however, but also in the previously mentioned direct
current components which can cause severe noise generation
on the motor at starting voltages of less than 50 %. The control
method used for these soft starters eliminates these direct
current components during the ramp-up phase and prevents the
braking torque which they can cause.

Fuse assignment
The type of coordination to which the motor feeder with soft
starter is mounted depends on the application-specific
requirements. Normally, fuseless mounting (combination of
motor starter protector and soft starter) is sufficient.
If type 2 coordination is to be fulfilled, semiconductor fuses must
be fitted in the motor feeder.

Configuration
Status graphs
If necessary, an overload relay for heavy starting must be
selected where long starting times are involved. PTC sensors are
recommended.
In the motor feeder between the SIRIUS 3RW soft starter and the
motor, no capacitive elements are permitted (e.g. no reactivepower compensation equipment). In addition, neither static
systems for reactive-power compensation nor dynamic PFC
(Power Factor Correction) must be operated in parallel during
starting and ramp-down of the soft starter. This is important to
prevent faults arising on the compensation equipment and/or the
soft starter.
All elements of the main circuit (such as fuses, controls and
overload relays) should be dimensioned for direct starting,
following the local short-circuit conditions. Fuses, controls and
overload relays must be ordered separately. Please observe the
maximum switching frequencies specified in the technical
specifications.
Note:
When induction motors are switched on, voltage drops occur as
a rule on starters of all types (direct starters, wye-delta starters,
soft starters). The infeed transformer must always be
dimensioned such that the voltage dip when starting the motor
remains within the permissible tolerance. If the infeed
transformer is dimensioned with only a small margin, it is best for
the control voltage to be supplied from a separate circuit
(independently of the main voltage) in order to avoid the
potential switching off of the soft starter.

The 3RW solid-state motor controllers are designed for easy
starting conditions. In the event of deviating conditions or
increased switching frequency, it may be necessary to choose a
larger device. For accurate dimensioning, use the Win-Soft
Starter selection and simulation program.
Win-Soft Starter selection and simulation program
With this software, you can simulate and select all Siemens soft
starters, taking into account various parameters such as mains
properties, motor and load data, and special application
requirements.
The software is a valuable tool, which makes complicated,
lengthy manual calculations for determining the required soft
starters superfluous.
You can order the CD-ROM under the following order number:
Order No. E20001-D1020-P302-V2-7400.

■ Function
At the same time the number of cables from the starter to the
motor is reduced from six to three. Compact dimensions, short
start-up times, easy wiring and fast commissioning make
themselves felt as clear-cut cost advantages.
The bypass contacts of these soft starters are protected during
operation by an integrated solid-state arc quenching system.
This prevents damage to the bypass contacts in the event of a
fault, e.g. brief disconnection of the control voltage, mechanical
shocks or life-related component defects on the coil operating
mechanism or main contact spring.
The starting current of particularly powerful operating
mechanisms can place an unjustifiable load on the local supply
system. Soft starters reduce this starting current by means of their
voltage ramp. Thanks to the adjustable current limiting, the
SIRIUS 3RW40 soft starter takes even more pressure off the
supply system. It leaves the set start ramp during the ramp-up –
the ramp gradient is fixed by the starting voltage and the ramp
time – as soon as the selected current limit is reached. From this
moment the voltage of the soft starter is controlled so that the
current supplied to the motor remains constant. This process is
ended either by completion of the motor ramp-up or by tripping
by the intrinsic device protection or the motor overload protection.
As the result of this function the actual motor ramp-up can well
take longer than the ramp time selected on the soft starter.
Thanks to the integrated motor overload protection according to
IEC 60947-4-2 there is no need of an additional overload relay
on the new soft starters. The rated motor current, the setting of
the overload tripping time (Class times) and the reset of the
motor overload protection function can be adjusted easily and
quickly. Using a 4-step rotary potentiometer it is possible to set
different overload tripping times on the soft starter. In addition to
Class 10, 15 and 20 it is also possible to switch off the motor
overload protection if a different motor management control
device is to be used for this function, e.g. with connection to
PROFIBUS.
Device versions with thermistor motor protection evaluation are
available up to a rating of 55 kW (at 400 V). A "Thermoclick"
measuring probe can be connected directly, as can a PTC of
type A. Thermal overloading of the motor, open-circuits and
short-circuits in the sensor circuit all result in the direct
disconnection of the soft starter. And if ever the soft starter trips,
various reset options are available the same as with intrinsic
device protection and motor load protection: manually with the
reset button, automatically or remotely through brief disconnection
of the control voltage.
Controlling the power semiconductors results not only in this
asymmetry, however, but also in the previously mentioned direct
current components which can cause severe noise generation
on the motor at starting voltages of less than 50 %.
The control method used for these soft starters eliminates these
direct current components during the ramp-up phase and
prevents the braking torque which they can cause. It creates a
motor ramp-up that is uniform in speed, torque and current rise,
thus permitting a particularly gentle, two-phase starting of the
motors. At the same time the acoustic quality of the starting
operation comes close to the quality of a three-phase controlled
soft starter. This is made possible by the on-going dynamic
harmonizing and balancing of current half-waves of different
polarity during the motor ramp-up. Hence the name "polarity
balancing".
As an option the thyristors can also be protected by SITOR
semiconductor fuses from short-circuiting so that the soft starter
is still functional after a short-circuit (coordination type 2). Three
LEDs are used to indicate the operating state as well as possible
errors, e.g. non-permissible tripping time (CLASS setting),
mains or phase failure, missing load, thermal overloading or
device faults.
• Soft starting with voltage ramp; the starting voltage setting
range Us is 40 to 100 % and the ramp time tR can be set from
0 to 20 s.
• Smooth ramp-down with voltage ramp; the running down time
toff can be set between 0 s to 20 s.
• Solid-state motor overload and intrinsic device protection
• Optional thermistor motor protection (up to size S3)
• Remote reset (integrated up to size S3, optional for size S6 and
larger)
• Adjustable current limiting
• Integrated bypass contact system to minimize power loss
• Setting with potentiometers
• Simple mounting and start-up
• Integrated status monitoring and fault monitoring
• Mains voltages 50/60 Hz, 200 ... 600 V
• Various control voltage versions
- sizes S0 to S3:
24 V AC/DC and
110 ... 230 V AC/DC
- sizes S6 to S12:
115 V AC and 230 V AC. Control by way of the internal
24 V DC supply and direct control by means of PLC are
possible.
• Wide temperature range from -25 to +60 °C
• Built-in auxiliary contacts ensure user-friendly control and
possible further processing within the system (for status
graphs see page 6/36)
The new series of devices comes with the "polarity balancing"
control method, which is designed to prevent direct current
components in two-phase controlled soft starters. On two-phase
controlled soft starters the current resulting from superimposition
of the two controlled phases flows in the uncontrolled phase.
This results for physical reasons in an asymmetric distribution of
the three phase currents during the motor ramp-up. This
phenomenon cannot be influenced, but in most applications it is
non-critical.

The space required by the compact SIRIUS 3RW40 soft starter
is often only about one third of that required by a wye-delta
assembly of comparable rating. This not only saves space in the
control cabinet and on the standard mounting rail but also does
away completely with the wiring work needed for wye-delta
starters. This is notable in particular for higher motor ratings
which are only rarely available as fully wired solutions.

Note:
These tables present sample set values and device sizes. They
are intended only for the purposes of information and are not

and must be optimized during start-up.
The soft starter dimensions should be checked where necessary
with the Win-Soft Starter software or with the help of Technical

Configuration
Status graphs
Note:
When induction motors are switched on, voltage drops occur as a
rule on starters of all types (direct starters, wye-delta starters, soft
starters). The infeed transformer must always be dimensioned
such that the voltage dip when starting the motor remains within
the permissible tolerance. If the infeed transformer is dimensioned
with only a small margin, it is best for the control voltage to be
supplied from a separate circuit (independently of the main
voltage) in order to avoid the potential switching off of the soft
starter.

A bypass contact system and solid-state overload relay are

The 3RW solid-state soft starters are designed for easy starting
conditions. In the event of deviating conditions or increased
switching frequency, it may be necessary to choose a larger
device. For accurate dimensioning, use the Win-Soft Starter
selection and simulation program.
Where long starting times are involved, the integrated solid-state
overload relay for heavy starting should not be disconnected.
PTC sensors are recommended. This also applies for the smooth
ramp-down because during the ramp-down time an additional
current loading applies in contrast to free ramp-down.
In the case of high switching frequencies in S4 mode, Siemens
recommends the use of PTC sensors. For corresponding device
versions with integrated thermistor motor protection or separate
thermistor evaluation devices see Catalog LV 1.
In the motor feeder between the SIRIUS 3RW soft starter and the
motor, no capacitive elements are permitted (e.g. no reactivepower compensation equipment). In addition, neither static
systems for reactive-power compensation nor dynamic PFC
(Power Factor Correction) must be operated in parallel during
starting and ramp-down of the soft starter. This is important to
prevent faults arising on the compensation equipment and/or the
soft starter.
All elements of the main circuit (such as fuses and controls)
should be dimensioned for direct starting, following the local
short-circuit conditions. Fuses, controls and overload relays
must be ordered separately. Please observe the maximum
switching frequencies specified in the technical specifications.
Win-Soft Starter selection and simulation program
With this software, you can simulate and select all Siemens soft
starters, taking into account various parameters such as mains
properties, motor and load data, and special application
requirements.
The software is a valuable tool, which makes complicated,
lengthy manual calculations for determining the required soft
starters superfluous.
You can order the CD-ROM under the following order number:
Order No. E20001-D1020-P302-V2-7400.
