400 kW HVAC drive — overload profile and panel fit
The 6SL3220-3YE60-0CB0: This SINAMICS G120X is a 400 kW infrastructure converter sized for pump, fan, and compressor duty in HVAC, water, and wastewater applications. The overload capability — 135% for 3 seconds, 110% for 60 seconds, 100% for 240 seconds — matches the variable-torque load profile where peak demand is brief and sustained overload is rare. Input accepts 3AC 380-480V +10/-20% at 47-63 Hz, covering the common global industrial mains without a step-down transformer. The built-in RFI suppression filter is Category C3, suitable for industrial second-environment installations where the drive is hard-wired to the supply. Enclosure is IP20 / UL open type, meaning it mounts inside a panel or cabinet that provides the environmental seal. The FSH frame size and the 800 x 1870 x 600 mm packaging dimensions give the panel builder the gland-plate and clearance numbers needed for the layout.
Fieldbus integration and operator interface
Integrated fieldbus options are MODBUS RTU, BACnet MS/TP, and USS — the three protocols most common in building automation and water/wastewater SCADA systems. No separate communication module is needed for these networks, which saves a slot and reduces the BOM count. Comes with an Intelligent Operator Panel (IOP) for local parameterization, fault diagnosis, and commissioning. The IOP supports plain-text menus and can be used to copy drive settings between units. No IO expansion module is included in this order code — the base unit handles the fieldbus interface and the IOP. If additional digital or analog I/O is needed, the SINAMICS G120X platform accepts plug-in IO expansion modules.
Lifecycle and ordering posture
Product class C means this unit is manufactured to order and cannot be returned or re-used. Plan the BOM freeze and delivery window accordingly — the lead time is confirmed at RFQ, not held as off-the-shelf stock. RoHS compliance effective March 2020, with a REACH Article 33 declaration for lead (CAS 7439-92-1) above 0.1% w/w. Export classification is AL: N / ECCN: EAR99H, which typically ships without an export license to most destinations.
