Cummins KTAA19-G6 vs Perkins 2806C-E18TAG1A
Compare Cummins KTAA19-G6 and Perkins 2806C-E18TAG1A by recorded output, operating duty, frequency and engine specifications. Their listed displacements are 19 L and 18 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.
