CUMMINS 250 KVA 6CTA A8.3-G4 MFG - 2011

250 kVA : 6CTAA8.3-G4

Lowest life cycle cost ‘C series’ design features have made Cummins® diesel, the standard for comparison of operating economy, reliability and long life. When all cost factors like initial purchase, fuel, lube oil, maintenance and overhaul are considered, the bottom line will show that this Cummins ® ‘C series’ will deliver the lowest life cycle cost.

Heavy duty, durable and emission compliant

Cummins ® ‘C series’ diesel engine comes with heavy duty features, bigger size camshaft, optimized turbo-matching and is yet compact in size with optimum power to weight ratio making it the obvious choice for your long-term power needs.
The genset powered by the reliable Cummins ® ‘C series’ diesel engine meets stringent exhaust emission tests as per MOEF norms without sacrificing fuel efficiency at normal operating loads.

Silent Power

Cummins ® 250 kVA enclosure is so designed as to have optimum performance and serviceability over the complete operating range. The enclosure is compact with integral fuel tank and is designed for ease in maintenance. The powder coated enclosure is manufactured on latest CNC machines to ensure superior finish and durability.
