The Siemens 6SE6420-2UC12-5AA1, also identified as 6SE64202UC125AA1, is a Siemens MICROMASTER 420 AC drive designed to provide reliable variable-speed control for small AC motors used in industrial automation, manufacturing, machinery, and general-purpose motor control applications. This drive supports a 1/3-phase 200�240 VAC input and is rated for 0.25 kW (0.33 HP) motor power with a rated output current of 1.7 A. The drive provides three-phase AC output and supports an output frequency range of up to 650 Hz.

The MICROMASTER 420 family provides flexible frequency conversion and dependable motor speed regulation for a wide range of general-purpose industrial applications. The 6SE6420-2UC12-5AA1 is an unfiltered version of the MICROMASTER 420 and is suitable for applications where the required EMC filtering is provided separately or is not required by the installation.

The Siemens 6SE6420-2UC12-5AA1 supports 150% overload capability for 60 seconds for constant-torque operation and also supports square-law torque applications. Its compact design, IP20 protection rating, and flexible frequency control make it suitable for small conveyors, pumps, fans, blowers, packaging machinery, machine equipment, and other low-power motor-control systems.
