The Siemens 6SE6440-2UD21-1AA1 is a 1.1 kW MICROMASTER 440 frequency inverter developed for adjustable-speed operation of three-phase industrial motors. Designed for 380–480 V AC systems, this drive provides a compact solution for machinery requiring reliable motor control and straightforward integration into an existing electrical panel.

This model is suitable for smaller production machines, pump units, conveying equipment and motor-driven auxiliary functions where the original MM440 platform must be maintained. Although it shares the compact FSA format with nearby power ratings, the correct replacement decision should be based on the complete Siemens order number and electrical data rather than physical appearance alone.
