The Siemens 6SL3056-4AA41-0AV0 is a panel-mount ammeter purpose-built for the SINAMICS V50 drive series. It reads motor current across a 0-950 A range from a standard 0-20 mA analog input — so you can pipe that signal straight into a PLC analog card or a local display without extra scaling hardware.
REACH Article 33 duty-to-inform compliance is covered under the current candidate list. No UL or IEC marks are listed in the evidence, so verify local code acceptance before specifying for a jurisdiction that requires them.
Group and product codes
Group Code R220 and Product Group 4923 are the internal Siemens classification tags. They don't change fit or function, but they help when cross-referencing in Siemens' own ordering tools or when a BOM line calls out these codes for traceability.
