450 kW overload profile for pump and fan duty
The 6SL3220-1YH62-0CB0 is a SINAMICS G120X infrastructure converter rated 450 kW with a 135% overload for 3 seconds, 110% for 60 seconds, and 100% for 240 seconds — a profile matched to centrifugal pump and fan starting torque where the peak demand is brief and the continuous load stays near the nameplate. It accepts 3-phase 500-690 V AC +10/-20% at 47-63 Hz, covering the common 575 V and 690 V industrial grids in North America and Europe without an external transformer.
Fieldbus integration for building automation
The drive ships with integrated MODBUS RTU, BACnet MS/TP, and USS protocols on the standard communication port — no option module needed for connection to a BAS controller or a water/wastewater SCADA system. No IO expansion or operator panel is included in the base unit; the control terminals and fieldbus interface handle start/stop, speed reference, and status feedback for remote operation.
Panel mounting and cooling in Size FSH
The FSH frame size with IP20 / UL open type protection requires mounting inside a ventilated enclosure — the drive relies on forced-air cooling from its internal fans, so the cabinet must allow free airflow through the heatsink fins and maintain ambient temperature between 0 and 45 °C.
Compliance and export documentation
RoHS compliant since March 2020, with a REACH Article 33 declaration for lead content above 0.1% w/w — the lead CAS-No. 7439-92-1 is present in certain component alloys and must be declared in the supply chain documentation. Export Control Classification is AL:N / ECCN:EAR99H, meaning no special export license is required for most destinations under US and EU regulations.
