Product Description: Siemens 6SE6440-2UC15-5AA1

The Siemens 6SE6440-2UC15-5AA1 is a line module in the SINAMICS S120 family, designed to feed the shared 600 V DC bus of the drive system. It accepts a 3-phase 380–480 V AC supply and provides a continuous current of 15 A. Integral protection functions—including overcurrent, short- circuit, and overvoltage protection—ensure reliable operation. The module communicates via the DRIVE-CLiQ interface for configuration and diagnostics, seamlessly integrating into the modular S120 architecture.
