The Siemens 6SL3056-4AA33-3AV0 is a panel-mount ammeter for the SINAMICS V50 drive family, scaled 0-330 A with a 0-20 mA analog input. The 0-20 mA loop is less susceptible to induced noise than a mV-level shunt signal, which matters when the meter shares a cabinet with switching power stages.
The product class is D: made to order against customer specifications, requiring engineering services.
For the panel builder: the 0-20 mA input is a two-wire loop, so the meter connects directly to the drive's analog output terminals — no external burden resistor. The 0-330 A scale is a direct read for drives feeding motors in that current band; verify your drive's rated output current matches the meter's full-scale before wiring. The meter itself is a SINAMICS V50 series component, so it shares the same form factor and mounting provisions as the drive module it pairs with.
