6RA7091-6FV62-0

The 6RA7091-6FV62-0, part of the Siemens SIMOREG series, is a DC master commutation protector equipped with advanced microprocessor technology. It is rated for a DC voltage of 480 volts and can manage a substantial DC current of 1,200 amperes across a 3-phase network. Designed for operation within an extended frequency bandwidth of 45 to 65 Hertz, this unit also has the ability to operate at a lower frequency range down to 23 Hertz and up to 110 Hertz, offering versatility for various applications.

Natural cooling is employed in this device to ensure optimal thermal management, enabling it to work effectively in ambient conditions from 0 to 55°C in non-condensing environments. Storage conditions also allow for a temperature range between -25 to 70°C under similar humidity standards. The protection rating stands as IP00, indicating that while the device is not sealed against dust or moisture, it is ideal for indoor use in controlled conditions.

The 6RA7091-6FV62-0 operates at a rated supply voltage of 380 to 460 volts AC and supports both open-loop and closed-loop control methods for precise adjustment of motor operations. It has a maximum power loss of 100 watts, making it energy efficient during operation. Furthermore, its installation altitude requirement is flexible, permitting operation at elevations up to 6,561.68 feet (2,000 meters) above sea level, making it suitable for various geographical installations. The pollution degree is rated at Degree 2, confirming its capability to function in moderately polluted environments.
