The Siemens 6SL3220-3YC20-0UB0 is a SINAMICS G120X variable frequency drive rated for 4 kW output power at 110% overload for 60 seconds (100% for 240 seconds), accepting 200-240 VAC three-phase input (+10/-20%, 47-63 Hz). This makes it a fit for 3-phase motor loads in that voltage class — pumps, fans, compressors — where the 110% overload handles short-duration starting or transient loads without oversizing the drive. Ambient temperature range is -20 to +45 °C, so it can sit in a non-conditioned cabinet near a hot process line or rooftop enclosure without derating until you push past 45 °C. The drive ships with an Intelligent Operator Panel (IOP) for local parameter access and commissioning, and integrates MODBUS RTU and BACnet MS/TP on the fieldbus side — no extra option card needed for building automation or plant-floor networks.
Frame size FSB, IP20 / UL open type enclosure. Painting class 3C2 means it tolerates moderate industrial atmospheres (humidity, some chemicals) but not direct spray. Packaged dimensions 400 x 350 x 195 mm, single-piece unit. No IO expansion module included — the base drive has the IOP and fieldbus; if you need additional I/O, order the optional IO expansion separately.
