Siemens 6SE6440-2AD33-0EA1 MICROMASTER 440 frequency inverter drive, 30kW, 380-480V AC.

The Siemens 6SE6440-2AD33-0EA1 is a MICROMASTER 440 series frequency inverter drive rated at 30kW output power. This three-phase AC drive operates on 380-480V input voltage and is designed for variable speed control of standard asynchronous motors in industrial applications.

The MICROMASTER 440 series is engineered for demanding variable-torque and constant-torque applications, including pumps, fans, compressors, conveyors, and general material handling systems. These drives feature vector control capability, integrated EMC filters, and comprehensive motor protection functions.

The MICROMASTER 440 range has been superseded by the Siemens SINAMICS series, making these units a legacy product. However, they remain widely deployed in existing industrial installations and process automation systems where replacement-in-kind is preferred over system upgrades.
