630 kW infrastructure drive — what the overload profile means for pump/fan duty
The 6SL3220-3YH68-0CB0 is a SINAMICS G120X converter rated 630 kW with a 135% overload for 3 seconds, 110% for 60 seconds, and 100% for 240 seconds — this overload profile maps to pump and fan starting torque demands where the peak comes at breakaway and drops off once the impeller spins up. Input range is 3AC 500-690 V +10/-20% at 47-63 Hz, with an integrated RFI suppression filter for Category C3 environments — the filter is built in, not a bolt-on kit, which saves a panel slot and avoids the wiring between drive and filter.
Fieldbus integration and panel fit
The drive ships with MODBUS RTU, BACnet MS/TP, and USS on the base board — no fieldbus option module needed for building automation or water/wastewater networks; the BACnet MS/TP interface connects directly to the BMS controller without a gateway. Size FSJ frame with IP20 / UL open type protection — the enclosure is ventilated for convection cooling and mounts in a clean indoor panel; the 1,200 x 1,857 x 800 mm shipping package gives the rough footprint for panel layout planning. Ambient rating is 0 to +45 °C — above that the drive must be derated or cabinet-cooled; the Intelligent Operator Panel (IOP) is included for commissioning and diagnostics without a laptop.
Lifecycle and compliance — active, RoHS, REACH
Product status is active — this is a current-production drive from Siemens, not a phase-out or NRND line; available to order against BOM quantities through authorized distribution. RoHS compliant since March 2020, with a REACH Article 33 declaration for lead (CAS 7439-92-1) above 0.1% w/w in certain components — the REACH notice is a supply-chain disclosure, not a restriction on use in industrial equipment. Export control classification is AL: N / ECCN: EAR99H — no special license required for most industrial destinations, but confirm the end-use country with your compliance team.
