Cummins 6LTAA8.9-G2 vs SDEC 6DTAA8.9-G5E3.1

Compare Cummins 6LTAA8.9-G2 and SDEC 6DTAA8.9-G5E3.1 by recorded output, operating duty, frequency and engine specifications. Their listed displacements are 8.9 L and 8.9 L, respectively. Start with the same duty and frequency, then check each model’s source and package conditions. These records alone do not establish interchangeability.

Compare matching ratings

Read across a row to compare the same operating duty and frequency. kWe is electrical output; mechanical kW is power at the engine shaft. kVA is apparent electrical power and is shown only when kWe is missing, without converting it. “Not listed” means the record lacks that rating, not zero output. Continuous and prime duties are kept separate. Check source documents, units and site conditions before comparing values.

An emissions classification in the catalog is not proof of certification for your engine or installation. Confirm the exact model, applicable documents and generator configuration.
