Siemens 6SE6440-2UD21-5AA1 MICROMASTER 440 VFD

The Siemens 6SE6440-2UD21-5AA1 is a compact 1.5 kW MICROMASTER 440 variable frequency drive for controlled operation of three-phase industrial motors. It accepts a 3 AC 380–480 V supply and delivers a rated output current of 4.10 A in high overload operation.

This model offers increased motor capacity while retaining the compact FSA frame format, making it appropriate for installed machines where space is restricted but a higher drive rating is required. Potential applications include packaging auxiliaries, small conveyor drives, feeders, pump systems and general production equipment maintained on the MM440 platform.
