Baudouin 12M55G3000/5 vs Cummins QSK78-G21

Compare Baudouin 12M55G3000/5 and Cummins QSK78-G21 by recorded output, operating duty, frequency and engine specifications. Their listed displacements are 65.65 L and 77.6 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.
