132 kW drive for 500-690 VAC pump and fan duty
The Siemens 6SL3220-3YH48-0UB0 is a SINAMICS G120X variable-frequency drive rated for 132 kW output with a 110% overload capability for 60 seconds and 100% for 240 seconds — sized for centrifugal loads where the peak torque demand is brief, like pump start-up or fan inertia. It accepts a 500-690 VAC 3-phase supply at 47-63 Hz, which covers the common 575 V and 690 V industrial distribution voltages in North American and European high-voltage motor installations.
Frame size FSF — panel integration and cooling
Frame size FSF with IP20 / UL open type protection means the drive is intended for enclosure mounting where the cabinet provides the environmental seal and airflow path — the drive itself is not sealed against dust or washdown. Packaging dimensions of 400 x 780 x 584 mm give a sense of the unit footprint; plan for top and bottom clearance per the manual for air circulation through the heatsink.
Fieldbus and operator interface
Integrated MODBUS RTU, BACnet MS/TP, and USS protocols cover the three most common building-automation and industrial serial networks — no separate communication module needed for BACnet integration into a BMS or MODBUS into a PLC. The Intelligent Operator Panel (IOP) is included, providing a local display for parameter access, fault diagnosis, and commissioning without a laptop.
Unfiltered topology — harmonic mitigation planning
The wide input voltage tolerance of +10/-20% on the 500-690 VAC nominal range allows the drive to ride through sags down to 400 VAC without tripping on undervoltage.
Compliance and documentation
RoHS compliant since July 1, 2006, and REACH Article 33 candidate-list information is available — both needed for EU-market equipment declarations and material compliance filings.
