The Siemens 6SL3220-3YD32-0CB0 is a SINAMICS G120XA variable frequency drive rated for 22 kW output on a 380 V to 440 V three-phase supply, with an integrated Class A C3 EMC filter. The FSD frame size (472 x 200 x 239 mm) and IP20 protection mean it mounts inside a control cabinet — not in a washdown or outdoor location. The integrated IOP-2 operator panel and onboard fieldbus (MODBUS RTU, BACnet MS/TP, USS) let a controls integrator commission it without an external gateway for building-automation or water/wastewater networks.
The 110% overload capability for 60 s per 600 s period is the key selection parameter for pump, fan, and compressor duty — it handles start-up and short-duration peak loads without oversizing the drive. The integrated Class A C3 filter meets the conducted emission limits for second-environment (industrial) installations per IEC 61800-3; if the drive goes into a residential or first-environment supply, an external Class A C2 or Class B filter may be required. The 6 DI / 4 DQ / 2 AI / 2 AO terminal complement covers most standalone applications without an expansion module: two analog inputs can take a 4-20 mA pressure or level transmitter, and the two analog outputs can drive an external meter or repeater.
The FSD frame has a 472 mm height, 200 mm width, and 239 mm depth — verify the cabinet depth allows rear clearance for the heat sink and the minimum 100 mm air gap above and below for natural convection cooling. IP20 means no gaskets or sealing; the cabinet door protects the drive from dust and accidental contact. The integrated IOP-2 panel can be mounted remotely if the drive is deep inside the enclosure; the connection cable is ordered separately (6SL3255-0AA00-4JA2).
