630 kW infrastructure drive — what it fits
The 6SL3220-3YH68-1CB0: This is a SINAMICS G120X, the Siemens family purpose-built for HVAC, water, and wastewater infrastructure — pump, fan, and compressor loads that run at constant torque or variable torque profiles. Rated 630 kW at 3AC 500-690 V, it handles the big iron in a central plant or lift station. The overload capability — 135 % for 3 s, 110 % for 60 s, 100 % for 240 s — matches the starting and transient demands of centrifugal pumps and fans. It is not sized for high-inertia conveyors or extruders; the short-duration 135 % peak is for breakaway torque, not sustained overload.
Fieldbus and integration for BAS networks
MODBUS RTU, BACnet MS/TP, and USS are onboard — no option card needed for building automation system (BAS) integration. BACnet MS/TP is the standard for HVAC plant controllers; MODBUS RTU covers the water/wastewater SCADA side. The Intelligent Operator Panel (IOP) and IO expansion are included in this order code. The RFI suppression filter is category C3, meaning it is certified for industrial environments where the supply is not shared with residential lines. For a 630 kW drive at 690 V, C3 is the expected filter class — it attenuates conducted emissions to EN 61800-3 second environment.
Lifecycle, compliance, and ordering posture
RoHS compliant since March 2020. REACH Article 33 duty applies — the drive contains lead (CAS 7439-92-1) above 0.1 % w/w in certain components, per the candidate list. Export control is AL:N / ECCN:EAR99H — no special license required for most destinations.
Physical footprint and handling
FSJ frame size — the packaging footprint is 1200 x 1857 x 800 mm. At this power level, plan for a floor-mounted cabinet or standalone enclosure; the IP20 / UL open type rating means it needs installation in a pollution-degree-2 environment or better.
