Siemens 6SE6440-2UD22-2BA1 MICROMASTER 440 Inverter

The Siemens 6SE6440-2UD22-2BA1 is a 2.2 kW / 3.00 hp MICROMASTER 440 frequency inverter designed for industrial motor applications requiring reliable variable-speed operation. Built for three-phase 380–480 V supply systems, it provides a rated high overload output current of 5.90 A.

Unlike the smaller FSA models in this MM440 range, the 6SE6440-2UD22-2BA1 uses an FSB frame format. This makes cabinet dimensions and mounting conditions particularly important when reviewing a replacement requirement. The drive may be relevant to conveyors, pump systems, mixing equipment, production machinery and other motor-driven industrial applications.
