7 Overview SIRIUS soft starters have all the same advantages as the 3RW30 soft starters. This also applies to the integrated bypass contact system. At the same time they come with additional functions, e.g. solid-state motor overload and intrinsic device protection and adjustable current limiting, optional thermistor motor protection (up to size S3), integrated remote RESET (up to size S3), as well as a two-phase control method (Polarity Balancing) that is unique in this performance range. SIRIUS soft starters are part of the SIRIUS modular system. This results in advantages such as identical sizes and a uniform connection method. Thanks to their particularly compact design, SIRIUS soft starters are only half as big as comparable wye-delta starters. Hence they can be mounted in minimum space in the control cabinet. Configuring and mounting are carried out quickly and easily thanks to the 3-wire connection. SIRIUS for three-phase motors Soft starters rated up to 250 kw (at 400 V) in three-phase networks. Extremely small sizes, low power losses and simple commissioning are just three of the many advantages of the SIRIUS soft starters. Application The SIRIUS 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.

13 Function SIRIUS soft starters have all the same advantages as the 3RW30/31 soft starters. At the same time they come with additional functions and a two-phase control method (Polarity Balancing) that is unique in the performance range up to 250 kw. Starting voltage, starting and ramp-down time of the voltage ramp and current limit are all easy to set using stepless rotary potentiometers, the same as on the SIRIUS 3RW30/31. The rated motor current, the setting of the tripping time and the resetting of the motor overload function are controlled like the SIRIUS overload relays by means of potentiometers and keys. Once again there is nothing new to get used to. SIRIUS comes with the new, patented control method called "Polarity Balancing", 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 starting operation of the motor. This phenomenon cannot be influenced, but in most applications it is non-critical. Controlling the power semiconductors in the two controlled phases results not only in this unbalance, 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 %. "Polarity Balancing" reliably eliminates these direct current components during the ramp-up phase. It creates a motor ramp-up that is uniform in speed, torque and current rise. At the same time the acoustic quality of the starting operation comes close to the quality of a three-phase controlled starting operation. This is made possible by the on-going dynamic balancing of current half-waves of different polarity during the motor ramp-up. The SIRIUS is equipped with optimum functionality. An integral bypass contact system reduces the power loss of the soft starter during operation. This reliably prevents heating of the switchgear environment. Using a 4-step rotary potentiometer it is possible to set different overload tripping times. Thanks to the integral motor overload protection to IEC there is no need of an additional overload relay. Device variants with integrated thermistor motor protection (PTC type A of Thermoclick) are available as an option for the sizes S0 to S3. This saves space in the control cabinet and wiring outlay in the feeder. Internal intrinsic device protection prevents in addition the thermal overloading of the thyristors and the power section defects this can cause. As an option, the thyristors can also be protected by SITOR semiconductor fuses from short-circuiting. And even inrush current peaks are reliably avoided thanks to adjustable current limiting. 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. We offer a comprehensive range of accessories for our soft starters. Examples include box terminal blocks, accessories for mechanical reset and a module for remote reset (size S or larger) or a sealing cover or easy-to-fit terminal covers for optimum touch protection. Soft starting with voltage ramp; the starting voltage setting range U s is 40 to 100 % and the ramp time t R can be set from 0 to 20 s. Smooth ramp-down with voltage ramp; the running down time t off can be set between 0 s to 20 s. The switch-off voltage U off is then dependent on the selected starting voltage U 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 S and larger) Adjustable current limiting Integrated bypass contact system to minimize power loss Setting with potentiometers Simple mounting and commissioning Integrated status monitoring and fault monitoring Mains voltages 50/0 Hz, 200 to 00 V Various control voltage versions - Sizes S0 to S3: 24 V AC/DC and 110 to 230 V AC/DC - Sizes S 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 possible. Wide temperature range from -25 to +0 C Built-in auxiliary contacts ensure user-friendly control and possible further processing within the system (for status graphs see Page /22).

21 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 circuit breaker and soft starter) is sufficient. If type of coordination 2 is to be fulfilled, semiconductor fuses must be fitted in the motor feeder.
