Overview
The Cummins NT855 is a 14.0 L 6-cylinder Cummins diesel engine supplied in 1 factory rating from 310 hp (231 kW) to 310 hp (231 kW). Every rating listed on this page is a complete engine for generator drive duty, not a generator set, and each unit ships with its serial number recorded against the specification sheet that applies to it.
Ratings in this family differ in rated speed, peak torque and emissions tier rather than in displacement or cylinder count, so the choice between them is a duty-matching question. The specifications panel and the per-rating entries on this page are generated from the same source data, so a rating quoted here can be matched directly against a delivery document.
Specifications
The specifications panel lists the family-level values that are common to every NT855 rating, including the 14.0 L displacement and the inline 6-cylinder layout. Ratings that share displacement and cylinder count but differ in output are listed individually in the model selection section.
Model Selection: NT855 Rating
Each entry in this section is one rating of the Cummins NT855. The rated power is the output at the stated speed; the peak torque figure is the value the rating develops at the lower speed shown, which is what normally decides whether a rating suits a given machine. Each rating carries a stable anchor, so a single rating can be linked or quoted directly.

NT855-GA — rated 231 kW (310 hp) at 1500 rpm.
Applications
NT855 engines in this family are normally specified for generator drive work.
Generator drive: ratings here are quoted at a fixed governed speed, and the engine is matched to the alternator frame and the prime/standby duty that the site actually needs.
Verification, Documentation and Ordering
Each engine is offered with nameplate verification + load-test record per serial number. That means the model and rating printed on the engine nameplate can be checked against the record issued for that serial number before shipment, which is the point most buyers of re-rated or re-exported engines want covered.
To receive a quotation, send the exact rating from the matrix above (for example NT855-GA), the machine or application it will drive, the quantity, and the destination port. If the rating you need is not listed, send the model and the required output and we will confirm whether it belongs to this family or to a neighbouring one.
Buyer tip: Send your NT855 specification, quantity and destination port for a verified quotation and lead time.
Frequently Asked Questions
What displacement and cylinder count does the NT855 use?
Every rating in this family shares the same 14.0 L displacement and inline 6-cylinder, 4-cycle configuration. Ratings differ in output, rated speed and emissions tier rather than in the base engine.
How is a NT855 rating ordered?
Send the exact rating shown in the model selection table, the application it will drive, the quantity and the destination port. The engine is then quoted against that rating and confirmed against its nameplate and load-test record.
At what speed is the NT855 rated?
The ratings on this page are governed at 1500 rpm. Rated speed fixes the speed the driven machine sees through its gearing, so confirm the governed speed before ordering rather than relying on the power figure alone.
Is the NT855 a complete engine or a generator set?
Every entry on this page is a complete engine. Generator sets and packaged gen-sets are listed separately from this family and are not included here.
