3RW4455-6BC35

The Siemens 3RW4455-6BC35 soft starter is a specialized device designed to enhance motor startup operations effectively. It is capable of operating within a voltage range of 400 to 600 Volts AC and complies with a rated control supply frequency of 50 to 60 Hertz. The current rating of this unit varies based on temperature conditions — it handles 693 amperes at 40°C, 615 amperes at 50°C, and down to 551 amperes at 60°C.

In terms of power capabilities, the soft starter can support 400 kilowatts at 400 volts for standard circuits and 710 kilowatts for inside-delta configurations. At 500 volts, the ratings are 500 kilowatts for standard circuits and up to 800 kilowatts for inside-delta applications. This versatility makes it suitable for various industrial environments.

The product is designed to function within an ambient operating temperature range of 0 to 60°C and can be stored in temperatures from -25 to 80°C, provided the conditions remain non-condensing. The unit is rated for installation at altitudes of up to 16,404 feet (5,000 meters) without performance degradation.

This soft starter is designed with screw-type terminals for easy electrical connections and can accommodate both stranded and finely stranded conductors. Three poles for the main current circuit allow for effective connection and integration into existing systems. Power loss is rated at 220 watts when operating at 40°C, ensuring efficiency during usage. The Siemens 3RW4455-6BC35 is an excellent choice for applications requiring reliable soft starter performance.
