380 kVA : NTA 14-G3

Diesel generator set N14 series

Lowest life cycle cost

N14 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 ® ‘N14 series’ will deliver the lowest life cycle cost.

Heavy duty, durable and emission compliant

Cummins ® ‘N14 series’ diesel engine comes with heavy duty features, bigger size camshaft, optimized turbo-matching, electrical STC Injectors 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 ® ‘N14 series’ diesel engine meets stringent exhaust emission tests as per MOEF norms without sacrificing fuel efficiency at normal operating loads.

Silent Power

Cummins ® 380 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.

Single source power assurance

Design, manufacture and testing of engine, alternator, enclosure and other accessories is done by Cummins Group of companies/ Channel partners (Powerica Limited) for that optimum performance integrity and is backed by countrywide product support network with single source responsibility for the entire package.
