630 kW overload profile — what it means for pump and fan sizing
The 6SL3220-1YH68-0CB0: Rated 630 kW continuous, with a 135% overload for 3 seconds, 110% for 60 seconds, and 100% for 240 seconds. For HVAC centrifugal loads, the 60-second overload covers starting inertia without oversizing the drive; the 3-second ceiling handles transient grid dips or valve slam events. Input range is 3AC 500-690 V +10/-20%, 47-63 Hz — covers 575 V and 600 V nominal supplies common in North American and European infrastructure sites without a step-down transformer.
Integrated fieldbus — no option card needed
MODBUS RTU, BACnet MS/TP, and USS are on-board — the drive talks directly to a building management system or PLC without a separate communication module. The BACnet MS/TP interface is the standard for HVAC/water/wastewater automation, so this drive drops into a BMS segment with no gateway.
Panel integration — size FSJ, IP20, and the RFI filter
Size FSJ frame, IP20 / UL open type — mounts inside a panel with top and bottom gland-plate clearance for the 3AC power and motor cables. The built-in RFI suppression filter (category C3) meets conducted emission limits for industrial second-environment (not residential), so no external filter is needed for most industrial or infrastructure sites.
Compliance and export control
RoHS compliant since 11 March 2020. REACH Article 33 duty to inform applies — the drive contains lead (CAS 7439-92-1) above 0.1% w/w in certain components. Export classification is AL:N / ECCN EAR99H, meaning no special license required for most destinations.
