About Siemens MICROMASTER 420 AC Inverter Drive (6SE6420-2UC22-2BA1), 3-Phase 240V output, 10.4 A rated current, Frame Size FSB, unfiltered, IP20 cubicle-mount motor controller

Regulate low-voltage AC motor speeds reliably with the legacy Siemens MICROMASTER 420 AC Frequency Inverter Drive (6SE6420-2UC22-2BA1). Part of the trusted MICROMASTER 420 (MM420) series, this Frame Size B (FSB) compact inverter steps down energy footprints by delivering precise V/f speed control for 3.0 HP (2.2 kW) induction motors. The flexible input section handles single-phase or three-phase 200240V AC incoming grid power, cleanly converting it into an adjustable three-phase output up to a 10.4 Amp continuous rating. Engineered for heavy factory floors, it tolerates a sharp 150% high overload capability for up to 60 seconds within a 300-second cycle time, utilizing an active cooling fan to operate reliably in ambient panel temperatures up to 50 C.

The core mechanical footprint incorporates a zero-clearance side-by-side cubicle mounting design (202 x 149 x 172 mm) with an IP20-rated protection shield to save tight cabinet real estate. For automated system workflows, it hosts 3 digital inputs, 1 analog input (010V), and 1 programmable relay output, along with built-in RS-485 interfaces optimized for distributed Modbus serial data pipelines.

Important Lifecycle & Module Note: This item has officially entered Product Cancellation / Spare Part status. To future-proof your new facilities, Siemens recommends migrating to the SINAMICS V20 or G120 micro-drive series. Additionally, the baseline unit arrives without an operator keypad panel (BOP/AOP); variable adjustments require plugging in a basic keypad or an external computer interface connection kit.
