55 kW VFD for pump and fan duty — what the ratings mean on a real line
The 6SL3220-3YE40-0UB0 is a SINAMICS G120X drive rated for 55 kW at 110 % overload for 60 seconds, 100 % for 240 seconds — the overload profile matches centrifugal loads (pumps, fans, compressors) where peak torque is brief and infrequent. It runs on 380-480 VAC three-phase, +10/-20 %, 47-63 Hz, unfiltered — the unfiltered input means the drive expects a line reactor or DC-link choke upstream if the supply is weak or has other VFDs on the same bus. The FSE frame size and IP20 / UL open-type enclosure suit panel-mount installation in a clean, ventilated electrical room — not a washdown environment, but standard for MCC-style layouts.
Fieldbus integration: MODBUS RTU and BACnet MS/TP on board
The drive ships with MODBUS RTU and BACnet MS/TP integrated — no option card needed for building automation or industrial serial networks. The Intelligent Operator Panel (IOP) is included for local parameter access and commissioning.
Lifecycle and compliance — active production, full documentation
RoHS compliance dated from July 2006. REACH Article 33 candidate-list information is available on request. Export control classification is AL: N / ECCN: N — no special licensing required for most destinations.
