Continuous S1 Duty
Engineered for sustained industrial operation under continuous-load conditions and long operating cycles.
Reliable continuous power for mid-scale industrial environments.
The CUMFA POWER™ NT855-SP400 is a mid-scale industrial genset built on the proven Cummins NT855 engine platform. With a 400 kVA nameplate rating and a verified continuous output of 320 kW, it is engineered for stable, controlled performance under continuous-duty industrial conditions.
Field-proven power. Globally trusted.
The CUMFA POWER™ NT855-SP400 delivers stable and reliable industrial power under continuous operating conditions. Built on the globally recognized Cummins NT855 platform, the SP400 configuration enhances cooling, combustion, control, and protection systems for improved durability and operational efficiency.
Verified load-test data with transparent performance information
| Model | Verified Output / Current | Validation Status |

400 kVA — 577 A |  Load-Tested Continuous / S1 |
Why is the verified output different from the nameplate rating?
The 400 kVA value represents the platform nameplate rating. The 400 kVA continuous output has been confirmed through on-site load testing at 1500 rpm, 400 V and 0.8 power factor under S1 continuous-duty conditions. This ensures that published performance reflects verified operating data rather than nominal ratings alone.
