Siemens 6SE6440-2UD33-0EB1 MICROMASTER 440 Inverter

The Siemens 6SE6440-2UD33-0EB1 is a MICROMASTER 440 industrial inverter rated at 30 kW for constant torque operation and 37 kW for suitable square-law torque applications. This product is designed for high-power motor control requirements in three-phase 380–480 V industrial systems.

With a larger 650 × 275 × 245 mm enclosure, the drive is relevant to installed production lines, industrial pump systems, processing equipment, conveying machinery and maintenance projects where an existing MM440 drive must be sourced or replaced. Because mechanical fit, duty type and wiring details become increasingly important at this power range, selection should be based on the full order number and machine information.
