56 A LO drive for pump and fan duty
The 6SL3220-3YD34-0UB0 is a SINAMICS G120XA AC drive from Siemens, built for variable-torque loads like pumps, fans, and compressors in HVAC and industrial process applications. It accepts 3-phase 380-440 V input at 47-63 Hz and delivers 56 A rated current in Low Overload (LO) duty — the rating that governs continuous operation on centrifugal loads where peak torque seldom exceeds 110%.
Mature lifecycle — still in active production
Lead time is quoted at 1-10 working days from Siemens distribution, making it a straightforward BOM line for new panel builds or replacement of an existing G120XA unit.
