SIRIUS 3RW40 soft starter is the most prominent feature is a small footprint. Integrated bypass contacts mean that after the motor starter, in the transaction without regard to the power semiconductors (SCR) power consumption. Thus reducing heat loss, making the design more compact, and no external bypass circuit. Meanwhile, soft starters have other integrated features such as adjustable current limiting, motor overload and intrinsic device protection, and optional thermistor motor protection. Because of these features, such as the need to purchase and install overload relays and other protective equipment, and therefore, the higher the motor rating, these features are more important. Internal intrinsic device protection prevents thermal overload and defect thyristor power area. Another option, you can use the thyristor semiconductor fuses prevent short circuits. Due to integrated status monitoring and fault monitoring, this compact soft starter has many different diagnostic functions. Using four LED and relay output to indicate the working status and power or phase failure, missing load, impermissible tripping time / level setting, thermal overload or equipment failure, etc., to achieve control and diagnostics. Starter rated power of 250 kW (400 V), can be used for standard applications in three-phase grid. Ultra-small size, low power consumption and simple starting just one of many advantages of the SIRIUS 3RW40 soft starter three. "Increased safety" protection EEx e, according to ATEX Directive 94/9 / EU S0 to S12 specifications 3RW40 soft starter for starting with "increased safety" type of protection EExe of explosion-proof motor. Catalogs and IC 10 of SIRIUS switching unit, see "Appendix" -> "Standards and Certification" -> "explosion-proof certification." Contact space functional compact SIRIUS 3RW40 soft starter is only required to compare ratings wye-delta starters third of the space required. This not only saves space in control cabinets and standard mounting rails, but also completely eliminates the wye-delta starter wiring work required. This is particularly evident for high motor ratings, these high ratings rarely used as a high-tech solution. At the same time, connect the starter motor cable and the required reduced from six to three. Compact dimensions, short start-up time, simple wiring and fast commissioning make soft starter has a significant cost advantage. These soft starter bypass contacts at work by an integrated solid-state arc system protection. Thereby preventing damage to the bypass contact when a fault, such as a coil spring operating mechanism or the main operation of the control voltage transient failure, mechanical shock or the defective part associated with life. Particularly powerful starting current operating mechanism will exert an uncontrollable load on the local power supply system. Through its voltage soft starter soft start to reduce the starting current. By adjustable current limit function, SIRIUS 3RW40 soft starter for power supply system to alleviate a lot of stress. Upon reaching the selected current limit, and the rest just set the starting point of the soft starter during starting (soft start lifting rate starting voltage and soft start time decision). From this moment, by controlling the voltage soft starter to the motor current is kept constant. Can be done by motor soft starters, intrinsic device protection tripping or motor overload trip to end the process. The result of this function is a long time to choose a soft start on the actual motor soft start time than the soft starter. Because integrated motor overload protection, and standard IEC 60947-4-2, the new soft starter without additional overload relay. Can be easily and quickly adjust the motor rated current, overload trip time (number of operations) to set and reset motor overload protection function. Using a 4-speed rotary potentiometer, you can set different overload tripping time in the soft starter. In addition to 10, 15 and 20, if a different motor management and control device for this function (such as connecting to PROFIBUS), but also cut off the motor overload protection. In addition, there is also provided with a thyristor motor protection device model analysis, rated power 55 kW (400 V when). A type PTC or Thermoclick measuring probe can be connected directly. Motor thermal overload and sensor circuit open circuit and short circuit will cause the immediate disconnection of the soft starter. If the soft starter once the trip, and the intrinsic device protection and motor load protection, as also offers a variety of reset options. Manual reset by reset button, by controlling the voltage transient is automatically disconnected or remote reset. The new device series with "polarity balancing" control method for the protection of two-phase controlled soft starter in DC components. For two-phase controlled soft starters, two control phases overlap current flows from uncontrolled phase. This also leads to physical cause motor soft starters in three-phase current asymmetric distribution. Although this is not affected, but in most applications still can not be ignored. Control not only leads to an asymmetric power semiconductors, when the starting voltage is less than 50% of the motor starting voltage value, the DC component also led to the previously mentioned serious noise. The control method used for these soft starters eliminates the DC component of the soft starter phase and prevents the braking torque that may arise. This method creates speed, torque and current rise on the same motor soft starters, enabling ease the two-phase motor starter. Meanwhile, the start-up operation of the three-phase control sound quality close to the soft starter. Can be achieved by the motor during the soft-start different polarity half-wave current ongoing dynamic coordination and balance. Hence the name "polarity balancing." Area of ??soft start and run application SIRIUS 3RW40 solid-state soft starters SIRIUS 3RW40 for three-phase asynchronous motors can stop control. By two-phase control, the entire starting time, all three of the current can be kept to a minimum, and to avoid the interference of DC components. This not only makes a two-phase motor starters up to 250 kW (400 V), the also avoids the current and torque peaks, such as the use of wye-delta starters produced.
