450 kW HVAC drive with 135% overload capacity
The 6SL3220-1YH62-0CP0 is a SINAMICS G120X infrastructure converter rated for 450 kW output power, delivering 135% overload for 3 seconds or 110% for 60 seconds, with 100% continuous duty for 240 seconds. That overload profile matches the starting and stall requirements of large centrifugal fans and pumps in HVAC and water/wastewater service — the 135% peak handles the inertia of a fan wheel without tripping on overcurrent, while the 110% sustained covers the ramp-up period.
Supply voltage, ambient limits, and enclosure
Input range is 3AC 500-690 V +10/-20% at 47-63 Hz, covering the common 575 V and 690 V industrial grids in North America and Europe. The drive is rated for 0 to +45 °C ambient with IP20 / UL open type enclosure — install it in a clean, ventilated cabinet; the IP20 rating means the drive itself is protected against solid objects larger than 12 mm but not against water ingress, so it needs a cabinet in wet environments. Size FSH frame — the packaging dimensions are 800 x 1,870 x 600 mm — so plan for a floor-mounted cabinet with adequate lifting provisions. The drive ships as a single piece, product class C, meaning it is manufactured to order and cannot be returned for credit once configured.
Fieldbus and I/O configuration
This variant ships with integrated PROFIBUS DP fieldbus — no operator panel and no IO expansion module included. For a water/wastewater or HVAC plant with an existing PROFIBUS backbone, this drive drops straight into the network without a gateway. If you need a different fieldbus (PROFINET, EtherNet/IP, BACnet), this is not the right order code; the G120X family has separate variants for each protocol.
