Drive sizing and overload profile for pump/fan loads
The SINAMICS G120X 6SL3220-3YH66-1CB0 is a 560 kW infrastructure converter sized for variable-torque HVAC, water, and wastewater applications. Its overload capability — 135 % for 3 s, 110 % for 60 s, 100 % for 240 s — matches the starting and short-duration peak demands of centrifugal pumps and fans without oversizing the drive frame. Input voltage 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. Ambient rating is 0 to +45 °C, with the IP20 / UL open type enclosure suited for indoor panel mounting.
Active production and made-to-order lead time
Export control classification is AL: N / ECCN: EAR99H, so no special license is required for most destinations. RoHS compliance is confirmed since March 2020; REACH Article 33 disclosure notes lead (CAS 7439-92-1) above 0.1 % w/w in certain components.
Fieldbus and operator interface onboard
The drive ships with an intelligent operator panel (IOP) and IO expansion, plus integrated MODBUS RTU and BACnet MS/TP fieldbus — no extra communication module needed for building automation or SCADA integration. The FSJ frame size and 1,200 x 1,857 x 800 mm packaging dimensions indicate a large cabinet-mount unit; plan gland plate and busbar access accordingly.
