500 kW HVAC/water drive — what the overload ratings mean
The 6SL3220-2YH64-1CF0 is a SINAMICS G120X infrastructure converter rated 500 kW, designed specifically for HVAC, water, and wastewater applications where pump and fan curves demand short-duration overloads rather than continuous high torque. The drive delivers 135% rated current for 3 s, 110% for 60 s, and 100% for 240 s — the 3-second ceiling handles inrush on large impellers starting against a closed valve, while the 60-second window covers the acceleration ramp without tripping on thermal accumulation.
Voltage range and filter — 500-690 V with C3 RFI suppression
Input range is 3AC 500-690 V +10/-20% at 47-63 Hz, covering 525 V, 575 V, and 690 V grids common in European and North American industrial plants without a step-down transformer. The built-in RFI suppression filter is category C3, meaning it meets conducted emissions limits for industrial environments (second environment per EN 61800-3) but is not suitable for residential or public low-voltage networks without additional external filtering.
Export control is AL: N / ECCN: EAR99H, meaning no special licensing is required for most commercial shipments outside embargoed destinations.
Compliance — RoHS, REACH, and lead declaration
RoHS compliant since 11-03-20, with a REACH Article 33 duty-to-inform declaration for lead (CAS 7439-92-1) above 0.1% w/w in certain components — a standard disclosure for industrial drives that use leaded solder or terminal plating.
Size FSJ — packaging and physical integration
Housed in size FSJ with IP20 / UL open-type protection, meaning the drive requires installation inside a locked electrical enclosure to meet touch-safe requirements — it is not a stand-alone outdoor unit. Packaging dimensions are 1,200 x 1,857 x 800 mm — the crate footprint is substantial, so plan for forklift access and a staging area during commissioning.
