560 kW HVAC/water drive with overload headroom
The 6SL3220-3YE66-1CP0: Rated 560 kW at 380-480 VAC, 47-63 Hz, this drive handles a 135% overload for 3 seconds and 110% for 60 seconds — the 135% burst covers pump start-up inrush and short-term process spikes without nuisance tripping. The 100% continuous rating for 240 seconds means it sustains full rated current through extended load events. The integrated RFI suppression filter is rated for category C3 environments (industrial second environment, not residential), so it meets conducted emissions limits for most industrial sites without an external filter. Ambient temperature range is 0 to +45 °C — derate above 45 °C per the standard Siemens derating curve. Fieldbus is PROFIBUS DP onboard, with an IO expansion slot and an intelligent operator panel included. The IP20 / UL open type enclosure is sized for cabinet mounting — the FSJ frame dimensions (1,200 x 1,857 x 800 mm packaging) indicate a large-footprint drive that needs a dedicated section in the panel.
