Product description 3.1 3 Fields of application Soft starters are used to start three-phase induction motors with reduced torque and reduced starting current. SIRIUS soft starter family The SIEMENS SIRIUS soft starter family comprises three different versions with different functionalities and prices. 3RW30 and 3RW40 Simple or standard applications are covered by the SIRIUS 3RW30 and 3RW40 soft starters and are described in this manual.
Product description 3.2 Basic physical principles of a three-phase induction motor 3.2 Basic physical principles of a three-phase induction motor SIRIUS soft starters are used to reduce the current and torque of a three-phase induction motor during the startup process. 3.2.1 Three-phase induction motor Fields of application Three-phase induction motors are used in a wide range of applications in commerce, industry, and trade owing to their simple, robust design and their minimal maintenance.
Product description 3.2 Basic physical principles of a three-phase induction motor Starting torque The starting torque and the breakdown torque can usually be assumed to be between two and four times the rated torque. From the point of view of the load machine, this means that the starting and acceleration forces exert a higher mechanical load on the machine and the product being conveyed compared to nominal operation.
Product description 3.3 Functional principle of the SIRIUS 3RW30 and 3RW40 soft starters 3.3 Functional principle of the SIRIUS 3RW30 and 3RW40 soft starters The SIRIUS 3RW30 and 3RW40 soft starters have two antiparallel thyristors in two out of the three phases. One thyristor for the positive half-wave and one for the negative half-wave is provided in each phase (refer to Fig. "Phase angle control and schematic diagram of a twophase controlled soft starter with integral bypass contacts").
Product description 3.
Product description 3.3 Functional principle of the SIRIUS 3RW30 and 3RW40 soft starters Bypass mode Once the motor has been started up correctly, the thyristors are subject to fully advanced control, meaning that the whole mains voltage is applied to the motor terminals. As the motor voltage does not have to be controlled during operation, the thyristors are bridged by integral bypass contacts that are rated for AC1 current.
Product description 3.3 Functional principle of the SIRIUS 3RW30 and 3RW40 soft starters The occurrence of DC components, caused by the phase angle and the overlapping phase currents, is a negative physical effect of two-phase control during the startup process that can mean a louder noise is produced by the motor. The "polarity balancing" control principle was developed and patented by SIEMENS to prevent these DC components during starting.

This is particularly important in connection with heavy-duty starting or if the fuse that is installed has already been operated close to the thermal tripping limit with the wye-delta assembly.
Product description 3.3 Functional principle of the SIRIUS 3RW30 and 3RW40 soft starters 3.3.3 Applications and use Applications and selection criteria The SIRIUS 3RW30 and 3RW40 soft starters represent a good alternative to direct or wyedelta starters.

5 Functions 5.1 Start modes You can choose between different startup functions reflecting the wide range of applications and functionality of the SIRIUS 3RW30 and 3RW40 soft starters. The motor start can be optimally adapted to each particular application. 5.1.1 Voltage ramp The SIRIUS 3RW30 and 3RW40 soft starters achieve soft starting by means of a voltage ramp. The motor terminal voltage is increased from a parameterizable starting voltage up to the mains voltage within a definable ramp-up time.
Functions 5.1 Start modes The SIRIUS 3RW40 soft starter has intrinsic device protection, current limiting, and ramp-up detection functions. These functions do not form part of the SIRIUS 3RW30 soft starter. CAUTION Risk of property damage When using the 3RW30: Make sure the selected ramp time is longer than the actual motor ramp-up time. If not, the SIRIUS 3RW30 may be damaged because the internal bypass contacts close when the set ramp time elapses.
Functions 5.
Functions 5.1 Start modes 5.1.2 Current limiting and ramp-up detection (3RW40 only) The SIRIUS 3RW40 soft starter measures the phase current (motor current) continuously with the help of integrated current transformers. The motor current that flows during the startup process can be actively limited by means of the soft starter. The current limiting function takes priority over the voltage ramp function.
Functions 5.1 Start modes Ramp-up detection (3RW40 only) The SIRIUS 3RW40 soft starter is equipped with an integrated ramp-up detection function. If it detects a motor startup, the motor voltage is immediately increased to 100 % of the mains voltage. The internal bypass contacts close and the thyristors are bridged. 0RWRU FXUUHQW , ,'LUHFW RQ OLQH VWDUWLQJ PRWRU ,6RIW VWDUWHU DGMXVWDEOH FXUUHQW OLPLW YDOXH %HJLQQLQJ GHWHU PLQHG E\ VSHFLILHG VWDUWLQJ PRGH LQ WKLV FDVH YROWDJH UDPS 0RWRU UXQ XS UHFRJQL
Functions 5.2 Stop modes 5.2 Stop modes You can choose between different stop modes reflecting the wide range of applications for SIRIUS soft starters. The motor stop can be optimally adapted to each particular application. If a start command is issued during the stop process, the process is interrupted and the motor is started again with the set start mode.
Functions 5.2 Stop modes 5.2.2 Soft stop (3RW40 only) In "soft stop" mode, the natural stop process of the load is decelerated. The function is used when the load must be prevented from stopping abruptly. This is typically the case in applications with a low mass inertia or a high counter-torque. Ramp-down time The "Ramp-down time" potentiometer on the soft starter allows you to specify how long power should still be supplied to the motor after the ON command is removed.
Functions 5.3 Motor protection / intrinsic device protection (3RW40 only) 5.3 Motor protection / intrinsic device protection (3RW40 only) NOTICE If the soft starter is disconnected because the motor overload protection or the intrinsic device protection trips, you must wait a defined cooling time (recovery time) prior to acknowledging the fault or starting the motor again.

WARNING Danger of death or serious injury.
Functions 5.3 Motor protection / intrinsic device protection (3RW40 only) Trip class (electronic overload protection) The trip class (CLASS) specifies the maximum time within which a protective device must trip from a cold state at 7.2 x the rated operational current (motor protection to IEC 60947). The tripping characteristics represent this time as a function of the tripping current (refer to chapter Motor protection tripping characteristics for 3RW40 (with symmetry) (Page 168)).
Functions 5.3 Motor protection / intrinsic device protection (3RW40 only) Recovery time (thermistor motor protection) If the thermistor motor protection is tripped, the soft starter cannot be restarted until the sensor installed in the motor has cooled down. The recovery time varies according to the temperature state of the sensor. 5.3.

The starter operates until the signal is removed again. If a ramp-down time is parameterized (3RW40 only), a soft stop starts as soon as the signal is removed.
Functions 5.5 Functions of the inputs For recommended circuits, e.g. control by means of pushbuttons, contactor contacts, or a PLC, refer to chapter Typical circuit diagrams (Page 175). 5.5.3 Thermistor input / connection on 3RW40 2 to 3RW40 4 24 V AC/DC rated control voltage After removing the copper jumper between T11/21 and T22, you can connect and evaluate either a Klixon thermistor integrated in the motor winding (at terminal T11/T21-T22) or a type A PTC (at terminal T11/T21-T12).
Functions 5.6 Functions of the outputs 5.6 Functions of the outputs 5.6.1 3RW30: Output terminal 13 / 14 ON The potential-free output contact at terminal 13/14 (ON) closes if a signal is present at terminal 1 (IN); it remains closed until the start command is removed. The output can be used, for instance, to control a line contactor connected upstream or to implement latching if you selected pushbutton control. For recommended circuits, refer to chapter Typical circuit diagrams (Page 175).
Functions 5.6 Functions of the outputs RUN The RUN output remains closed as long as the motor is controlled by the soft starter, in other words during the startup phase, in bypass mode, and during the soft stop (if set). This output function can be used, for instance, if a line contactor connected upstream must be controlled by the soft starter, especially if the soft stop function is set. BYPASSED The BYPASSED function can be used, for instance, to indicate that the motor has started up successfully.

Configuration 11.2 Startup class 11.2 Startup class To achieve the optimum soft starter design, it is important to know and take into account the ramp-up time (startup class) of the application. Long ramp-up times mean a higher thermal load on the thyristors of the soft starter. An appropriately dimensioned SIRIUS 3RW40 or 3RW44 soft starter should be chosen for startup processes with a motor ramp-up time > 20 s. The maximum permissible ramp-up time for SIRIUS 3RW30 soft starters is 20 seconds.
Configuration 11.2 Startup class 11.2.1 Application examples for normal starting (CLASS 10) with 3RW30 and 3RW40 Recommended basic parameter settings Assuming the conditions and constraints indicated below apply, the size of the soft starters can be equivalent to the motor rating for a normal starting characteristic (CLASS 10). You can find a suitable soft starter for the required motor rating based on the required startup class in chapter Technical data (Page 127).
Configuration 11.2 Startup class 11.2.2 Application examples for heavy-duty starting (CLASS 20): 3RW40 only Recommended basic parameter settings Assuming the conditions and constraints indicated below apply, the soft starter size must be at least one power class higher than the motor rating for heavy-duty starting (CLASS 20). You can find a suitable soft starter for the required motor rating based on the required startup class in chapter Technical data (Page 127).
Configuration 11.3 ON time and switching frequency 11.3 ON time and switching frequency Based on the rated motor current and the startup class, the SIRIUS 3RW30 and 3RW40 soft starters are dimensioned for a maximum permissible switching frequency in combination with a relative ON time (refer to chapter Technical data (Page 127)). If these values are exceeded, a larger soft starter may have to be selected.
Configuration 11.4 Reducing the rated data 11.4 Reducing the rated data You can reduce the rated data of the SIRIUS 3RW30 and 3RW40 soft starters if ● The installation altitude is higher than 1000 m. ● The ambient temperature in the switching device's environment exceeds 40 °C. ● The lateral clearances described earlier are not complied with, e.g. side-by-side assembly or direct mounting of other switching devices (assembly type). ● The vertical mounting position is not complied with. 11.

Technical data 13.1 3RW30 13.1.1 Overview 13 SIRIUS 3RW30 soft starters reduce the motor voltage through variable phase angle control and increase it from a selectable starting voltage up to the mains voltage within the ramp time. They limit the starting current and torque, so that the shocks that occur during direct starts or wye-delta starting are avoided. Mechanical loads and mains voltage dips can be effectively prevented in this way.

Technical data 13.2 3RW40 13.2 3RW40 13.2.1 Overview SIRIUS 3RW40 soft starters have all the same advantages as the 3RW30 soft starters. SIRIUS 3RW40 soft starters are characterized above all by their small space requirements. Integral bypass contacts mean that no power loss has to be taken into account 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.
