630 kW VFD for infrastructure pump and fan duty
The Siemens 6SL3220-1YH68-1CP0 is a SINAMICS G120X infrastructure converter rated 630 kW at 500-690 V, 47-63 Hz, with a 135% overload capability for 3 seconds and 110% for 60 seconds — the kind of headroom that holds the unit on the grid when a large ID fan or boiler feed pump demands a transient torque spike without tripping the drive. It ships as an IP20 / UL open type unit in Size FSJ, with an integrated RFI suppression filter for category C3 and a PROFIBUS DP fieldbus interface — no separate filter or communication module needed for a standard infrastructure installation.
Overload profile and ambient limits
The drive delivers 630 kW continuous, with 135% current for 3 seconds and 110% for 60 seconds, then 100% for 240 seconds — this matches the starting and short-time overload demands of centrifugal pumps, fans, and compressors in water/wastewater and HVAC plants, provided the ambient stays between 0 and 45 °C. Below 45 °C the drive runs at full rated output; above that the output current must be derated per the SINAMICS G120X manual — a consideration for enclosed panels or hot machine rooms where the internal air temperature climbs above the ambient spec.
Compliance documentation for regulatory filing
RoHS compliant since 11 March 2020, with a REACH Article 33 disclosure for lead (CAS 7439-92-1) above 0.1% w/w — the lead is in the electronic components and solder joints, a standard declaration for industrial drives. Export control classification is AL: N / ECCN: EAR99H, meaning no special license is required for shipment to most destinations, but the buyer should verify end-use and end-user restrictions per their own compliance program.
