The Siemens 6SL3210-5BB21-5UV0 is a SINAMICS V20 spare-part drive rated for 1.5 kW on a 200-240 V 1-phase AC supply, with a 150% overload capability for 60 seconds. Unfiltered, it carries IP20 / UL open-type protection — intended for cabinet mounting, not standalone washdown. Onboard I/O includes 4 digital inputs, 2 digital outputs, 2 analog inputs, and 1 analog output; fieldbus is USS or MODBUS RTU via the built-in Basic Operator Panel (BOP).
What the ratings mean for fit
The 150% overload for 60 s means this drive can handle a momentary load surge — typical for a pump or fan starting against a closed valve — without tripping. The unfiltered variant (no internal EMC filter) keeps conducted emissions higher, so it's suited for installations where an external line filter is already present or where the drive is close to the transformer. IP20 / UL open type means it must live inside an enclosure with a minimum IP54 gland plate; the 140 x 160 x 165 mm (WxHxD) footprint fits a standard 200 mm deep cabinet.
