The Siemens 6SL3210-5BB21-1AV0 is a SINAMICS V20 variable frequency drive rated for 1.1 kW output from a 200-240 V 1-phase AC supply, with a 150% overload capability for 60 seconds. It includes an integrated EMC filter (Category C2), onboard I/O (4 DI, 2 DO, 2 AI, 1 AO), and built-in USS/MODBUS RTU fieldbus with a basic operator panel (BOP).
The datasheet carries a revision date of 04.03.2021 with the standard Siemens copyright notice, indicating the design and specifications are stable.
The 150% overload for 60 seconds is the figure that governs real-world motor starting and short-term load peaks — a pump or fan with a 1.1 kW motor can accelerate under load without tripping on current limit. The integrated C2 filter means this drive meets conducted emission limits for industrial environments (second environment) without an external filter, saving panel space and wiring time. Dimensions of 140 x 160 x 165 mm (WxHxD) fit the standard V20 compact footprint; verify panel depth clearance before committing the BOM line.
