Introducing Advantages and Hot Models of Siemens SIRIUS 3RW4436 soft starter series Siemens 3RW4436 belongs to Siemens SIRIUS 3RW44 soft starter series, the following are its advantages and related hot models introduction: **Advantages** Variety of starting functions: soft starting can be performed by burst pulse, torque control, voltage ramp, adjustable torque or current limiting function, and any combination thereof, which can meet the starting needs of different load types such as fans, pumps and so on. **Integrated bypass contact:** After detecting the completion of motor soft start, the bypass contact integrated in the soft starter will bypass the thyristor, which significantly reduces the heat loss of the soft starter during the rated value, prolongs the service life and improves the working efficiency. **Perfect protection function:** with electronic motor overload protection and equipment self-protection function, it can prevent the thermal overload of power unit thyristor; it also has the functions of phase failure protection and overheating protection, which can effectively protect the motor and the soft starter itself. **Convenient parameter setting:** using multi-line display with backlight illumination, keys and menu prompts for operation and debugging, through the four-key operation and plain text display, after selecting the menu language, only a few simple steps of setting, you can optimize the parameters of the motor soft start and soft stop quickly, easily and reliably. **Good communication:** The optional PROFIBUS DP module, with its communication functions, programmable control inputs and relay outputs, allows the soft starter to be integrated into the controller for easy remote control and monitoring. **Simple wiring:** motor wiring is relatively easy, low installation and commissioning difficulties. Wide range of applications: the main circuit power supply voltage range is 200V-690V, 50Hz-60Hz, and the applicable temperature is up to 60ºC (capacity reduction starts from 40ºC), so it can be used in a variety of industrial environments and under different power supply conditions. **Hot Models about Siemens 3RW4436** [3RW4436-6BC44](https://www.cwlyautomation.com/product/5277.html "3RW4436-6BC44"): with a motor power of 90kW and a rated current of 162A at 400V, it is suitable for many industrial environments with medium power requirements. [3RW4436-2BC44](https://www.cwlyautomation.com/product/5276.html "3RW4436-2BC44"): compression spring connection, also for motors up to 90 kW. [3RW4436-2BC45](https://www.cwlyautomation.com/product/5284.html "3RW4436-2BC45"): rated working voltage 400V-600V, adaptable motor power of 110kW, in some of the higher voltage requirements, power demand is relatively large occasions more applications. [3RW4436-2BC46](https://www.cwlyautomation.com/product/5285.html "3RW4436-2BC46"): compression spring wiring, corresponding to Amp standard 162, suitable for motor power of 160kW (250kW under internal delta wiring), can be used in some large-scale equipment with higher requirements for starting power.
