Siemens 6SE64202UD215AA0 Micromaster 420 — Compact 1.5 kW AC Drive

The Siemens 6SE64202UD215AA0 Micromaster 420 is a compact variable frequency drive engineered for reliable, everyday motor control in commercial and industrial settings. Optimized for small to mid-size machinery, it delivers stable performance, simple commissioning, and proven Siemens quality in an IP20 chassis for cabinet installation. This model is immediately available with free shipping and backed by a 2-year warranty to help you restore uptime fast.

Power, Voltage, and Frequency Range

Designed for global 460 V-class systems, the Micromaster 420 accepts a 3-phase 380–480 VAC input at 47–63 Hz with an input current of 5.8 A. On the output side, it provides 3-phase 0–480 VAC across a wide 0–650 Hz frequency range with a continuous current of 4 A. This flexibility supports precise speed control, soft starting, and smooth acceleration and deceleration, reducing mechanical stress while improving process consistency.

Motor Compatibility and Performance

Rated for motors up to 1.50 kW, this drive is a strong fit for applications such as small conveyors, fans, pumps, mixers, and general-purpose automation tasks. The Micromaster 420 architecture emphasizes dependable torque delivery and stable low-speed operation, enabling better throughput and reduced energy consumption compared to across-the-line starting. Its unfiltered configuration provides a straightforward baseline for installations where external EMC filtering is specified at the panel level.

Control, Integration, and Operation

The 6SE64202UD215AA0 offers practical I/O and parameter sets that streamline commissioning and daily use. Standard control terminals support common run/stop, direction, and analog speed reference schemes, while parameterization can be completed quickly using a keypad or PC software, depending on your chosen accessories. The IP20 open-type enclosure is intended for protected control cabinets, providing easy access for wiring, maintenance, and future expansion.

Lifecycle Status and Availability

The manufacturer discontinues this catalog number as of 03/01/2011, yet it remains widely deployed due to its durability and familiar Siemens parameter structure. To support your maintenance strategy and minimize downtime, units are in stock, ship free, and include a 2-year warranty. Immediate availability means you can keep critical lines running without waiting on long lead times.
