Buying 6SL3120-2TE21-0AD0 from Flexa Systems
Buy the Siemens 6SL3120-2TE21-0AD0 SINAMICS VFD, in stock refurbished and available brand new on request, or send yours to Flexa Systems for repair. This drive is rated for a 480 VAC 3-phase supply and 9 A, which places it in motor control panels fed from a 480 V plant bus, driving a motor whose current stays within that rating. When one drops out on a conveyor, pump or process line, ordering the exact same part number keeps the voltage and current rating identical to what the panel was designed around. Each refurbished unit is tested before shipment, carries a 2-year warranty and typically saves 30-60% compared with new.
Repair option: send in your faulty unit for component-level repair — $990.00 with free diagnostics, a 2-year warranty, and a 5–30 business day turnaround. Repair typically costs 40–70% of a new unit, saving you 30–60%. Learn more about our Siemens repair and VFD repair service.

6SL3120-2TE21-0AD0 FAQ
What should I check before swapping in a replacement 6SL3120-2TE21-0AD0?
Confirm the motor nameplate current falls within the 9 A rating and that your supply is 480 VAC 3-phase. Back up the parameters from the existing SINAMICS drive so they can be reloaded onto the replacement.
Should I buy the 6SL3120-2TE21-0AD0 refurbished or brand new?
The refurbished unit is in stock, so it is the quicker way to get a stopped line running again with the same 480 VAC, 9 A rating. Brand new is available on request if your maintenance policy calls for unused spares.
