450 kW at 500-690 V — what the duty cycle means for your pump or fan load
The SINAMICS G120X 6SL3220-1YH62-1CF0 is a size FSH infrastructure converter rated for 450 kW continuous output. The duty cycle is specified as 135% for 3 seconds, 110% for 60 seconds, and 100% for 240 seconds — this overcurrent profile is tailored for HVAC and water/wastewater loads where starting inertia and short-duration overloads (like a clogged pump or fan stall) are the norm, not continuous high-torque demands. Input voltage range is 3 AC 500-690 V +10/-20% at 47-63 Hz, which covers standard 575 V and 690 V industrial supplies in North America and Europe. The integrated RFI suppression filter meets category C3, meaning it's suitable for industrial second-environment installations where the drive is hard-wired to a dedicated transformer, not a residential or public low-voltage grid.
Fieldbus integration and commissioning
This drive ships with PROFINET PN and Ethernet IP integrated on the control board — no separate communication module needed. The IO expansion slot is populated but the operator panel is omitted, so initial parameterization requires a PC connection via the SINAMICS Startdrive or G120X Smart Access web server. For a line-down swap, the PROFINET device name and IP address must match the original; the drive stores the configuration on a removable memory card (not included). The ambient temperature range is 0 to +45 °C without derating. Above that, the drive must be derated per the SINAMICS G120X operating instructions — typically 1.5% per °C up to 60 °C, which matters if the panel sits in a non-conditioned mechanical room or near a boiler.
Sourcing and compliance reality
The product class code C indicates it is manufactured to order, so lead times are project-dependent and confirmed at RFQ. No direct pin-compatible alternative exists within the SINAMICS G120X family at this power level; the frame size FSH is unique to the 450 kW rating. RoHS compliance is confirmed since 11-03-2020. The part contains lead (CAS 7439-92-1) above 0.1% w/w per REACH Article 33 — this is typical for power semiconductor solder joints and does not affect installation or operation, but must be declared in the supply chain documentation. Export control is AL N / ECCN EAR99H, meaning no special license is required for most industrial destinations.
Physical footprint and panel integration
Packaged dimensions are 800 x 1,870 x 600 mm — this is a floor-standing cabinet drive, not a wall-mount unit. The IP20 / UL open type enclosure means it requires installation inside a rated electrical panel; the incoming cable gland plate and busbar connections must be sized for the 450 kW continuous current (approximately 450 A at 690 V).
