400 kW at 135% overload — sized for pump and fan duty cycles
The 6SL3220-1YE60-0CB0 is a SINAMICS G120X infrastructure converter rated 400 kW on a 3-phase 380-480 VAC supply, with an overload profile of 135% for 3 seconds, 110% for 60 seconds, and 100% for 240 seconds — a duty cycle matched to centrifugal pump and fan loads where peak torque demand is brief and infrequent. The input accepts 380-480 VAC +10/-20% at 47-63 Hz, covering the global 400/480 V class without a transformer, provided the supply neutral is solidly grounded per the installation standard.
Fieldbus integration for building management systems
The integrated fieldbus ports support MODBUS RTU, BACnet MS/TP, and USS on the same physical connection — the drive auto-detects the protocol at power-up, so the controls integrator assigns the bus address and baud rate in parameter group 2030 and the drive joins the BMS segment without a separate gateway card. No IO expansion module or operator panel is fitted as standard; the base unit carries the onboard I/O for start/stop, setpoint, and fault feedback, which is sufficient for most HVAC single-zone or booster-pump applications.
FSH frame size and IP20 enclosure — panel fit and cooling
The FSH frame measures 800 x 1870 x 600 mm (L x W x H) and is rated IP20 / UL open type, meaning it requires installation inside a clean, dry enclosure with forced-air ventilation sized for the drive's published heat dissipation — the bottom cable entry and top air exhaust path must be kept clear of obstructions. The RFI suppression filter is category C3 per EN 61800-3, suitable for industrial second-environment networks; for residential or first-environment compliance an external EMC filter may be needed ahead of the drive.
Active production — no obsolescence risk on this BOM line
RoHS compliance is confirmed since 11 March 2020, and the REACH Article 33 declaration notes lead (CAS 7439-92-1) above 0.1% w/w in certain component materials — this is a standard SVHC disclosure for power electronics with soldered joints and does not restrict installation in EU markets. Export Control Classification is EAR99H under ECCN, which means no US export license is required for most commercial destinations, though end-use and end-user screening still applies per EAR Part 744.
