450 kW HVAC drive with C3 filter and dual-fieldbus
The 6SL3220-1YE62-0CB0: This SINAMICS G120X is a 450 kW infrastructure converter built for HVAC, water, and wastewater fan/pump loads. The 135% overload for 3 seconds (110% for 60 seconds, 100% for 240 seconds) matches the starting torque profile of centrifugal fans and pumps — no need to oversize the drive for duct static pressure recovery. The integrated RFI suppression filter meets category C3 for 3AC 380-480V +10/-20% at 47-63 Hz, so it ships ready for European EMC environments without an external filter on the line side. Ambient temperature rating is 0 to +45 °C without derating — above that, the drive current must be reduced per the SINAMICS G120X manual curves.
Fieldbus and I/O configuration for BMS integration
The drive ships without an operator panel or IO expansion module, but the integrated fieldbus supports MODBUS RTU and BACnet MS/TP natively via the USS protocol — the two most common BMS communication standards for HVAC plants. The BACnet MS/TP interface lets the building automation system poll drive status and issue speed commands directly over RS-485. Size FSJ enclosure with IP20 / UL open type protection means it mounts inside a panel or electrical room — not outdoors. The packaging dimensions are 1,200 x 1,857 x 800 mm, so plan for a lift truck or pallet jack at receiving; this is not a hand-carry unit.
The lifecycle stage is mature and the product status is active — Siemens still manufactures this order code. Product class C means it is produced to order and cannot be returned, so confirm the BOM quantity and voltage before committing.
