Siemens 6SE6440-2UD24-0BA1 MICROMASTER 440 VFD

The Siemens 6SE6440-2UD24-0BA1 is a 4 kW / 5.00 hp MICROMASTER 440 variable frequency drive intended for three-phase industrial motor applications requiring stable speed control and high overload capability. Operating from a 380–480 V supply, it provides a rated high overload output current of 10.20 A.

This FSB-format inverter can be relevant to larger conveyor sections, motor-driven processing equipment, pumps, production machinery and installed MM440 systems requiring a matching Siemens replacement. For buyers planning beyond immediate maintenance, this model may also form part of a wider review of replacement or modernization requirements.

As the MICROMASTER 4 family approaches final discontinuation, customers considering long-term system support may request assistance reviewing a suitable newer Siemens drive option alongside the original MM440 requirement.
