Siemens 6SE6420-2UC13-7AA1 Variable Frequency Drive

Siemens MICROMASTER 420 6SE6420-2UC13-7AA1 is a compact, single‑phase variable frequency drive for speed controlling small AC motors rated at 200–240 VAC. Belonging to the MICROMASTER MM420 family, this unfiltered drive delivers 0.37 kW of continuous torque with a 150% overload capacity for 60 seconds and operates over 47–63 Hz to match load requirements. Its enclosure is IP20 and the physical footprint measures 173 × 73 × 149 mm (H × W × D), suitable for installation in compact control panels and benchtop assemblies. Rated for ambient temperatures from -10 °C to +50 °C, the unit is configured without AOP/BOP options, which simplifies integration where an operator panel is not required. With 1-phase input on a 200–240 V supply, it provides reliable speed control for small conveyors, pumps, fans, and other light industrial machines where smooth acceleration, deceleration, and torque control are important. The 6SE6420-2UC13-7AA1 designation identifies the same MM420 module commonly encountered in replacement parts catalogs and MRO listings, ensuring compatibility with Siemens’ legacy MM420 installations and easy sourcing through major distributors.
