The 6SL3700-0LE43-2BU3 by Siemens is a robust line connection module within the SINAMICS S120 series, tailored for versatile power handling. This module can function with an AC voltage range from 380 V to 480 V, making it suitable for various industrial applications. It is specifically constructed for a 3-phase system, running efficiently within frequency parameters of 50 Hz to 60 Hz.

With a current rating of 3200 A, this unit is built to manage high power demands effectively. The enclosure is classified as NEMA 1, providing moderate protection against environments where dust and debris are minimal. It also has an IP20 rating for ingress protection, indicating that it is resistant to solid objects, but not protected against liquids, making it suited for internal installations.

Cooling is achieved through an air-cooled mechanism, which helps maintain optimal operating temperatures under load. This module is designed to work in humidity levels up to 80% maximum, ensuring reliability in conditions prone to moisture. The permissible maximum altitude for operation is up to 1000 meters above sea level, which allows for its use in various geographical settings, retaining performance and stability.
