Cummins QSNT-G3 vs Isuzu 6WG1X

Compare Cummins QSNT-G3 and Isuzu 6WG1X by catalog output, operating duty, frequency and engine specifications. Their listed displacements are 14 L and 15.681 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.

Isuzu 6WG1X: Electrical output includes catalog estimates. Check the calculation basis and source document on the model page; these are not verified complete-generator ratings. Rating details

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.
