Key Benefits
- Delivers 261 kW (350 HP) at 1800 rpm from 14 L as a factory-rated assembly.
- Peak torque of 1385 N.m @ 1500 rpm holds the load without downshifting or derating.
- Turbocharged/Aftercooled induction keeps charge temperature under control in continuous duty.
- Supplied to CCS/IMO Certificates, so the unit can be registered in markets that require it.
- Dry weight 1430 Kg and envelope 1809mm*881mm*1598mm are published so the installation can be checked before ordering.
- Published fuel consumption of ≤ 220 g/kW.hr makes running cost predictable.
Application Scenarios
- Prime mover for a new generator set build
- Standby set engine replacement
- Rental power fleet rebuild
- Containerised power module
Who It Is For
- Genset packagers matching an engine to an alternator
- Rental power companies rebuilding sets between contracts
- Industrial sites replacing the prime mover in an existing canopy
- Telecom and data infrastructure contractors specifying standby power
Problems It Solves
- An engine that does not hold speed under block load makes the whole set unusable.
- Packagers lose weeks when the engine does not match the alternator and the base frame.
- Standby sets sit idle for months and must still start and take load on demand.
- Identifying the right NTA855-M350 variant from a serial number takes experience; MEP Power checks the configuration before quoting.

- Match the flywheel and SAE housing to the alternator before assembly
- Set the governor to the frequency required, 50 Hz or 60 Hz

How It Compares
| Compared with | What to consider |
|---|---|
| A rebuilt or used engine of the same rating | A rebuilt unit may show the same 261 kW (350 HP) on paper, but its running history is unknown and the warranty rarely covers the whole engine. |
| A larger engine in the same KTA19 range | Moving up a frame size adds weight, envelope and fuel burn; specify the next size up only if the duty cycle really needs the headroom. |
| A non-Cummins engine of similar output | Parts and service for Cummins families are available in most markets, which matters more over ten years than the purchase price on day one. |
