The Cummins NT855-GA is the world-famous 200–280 kW prime / 220–308 kW standby workhorse that has powered the planet for over 40 years in mining, oilfields, construction, telecom, hospitals, and remote camps. Built around the unbreakable NT855-GA big-bore engine—14L, 6-cylinder in-line, direct-injection with PT fuel pump and rock-solid mechanical governor—it is the definition of “set-and-forget” reliability.

Feature	Customer Benefit
14L 6-Cylinder Naturally Aspirated / Turbocharged Engine with PT Fuel System	200–280 kW prime in an indestructible cast-iron block; 30,000+ hour TBO, runs on any diesel worldwide — no electronics, no sensors, no DEF.
200–280 kW Prime / 220–308 kW Standby @ 50 Hz	Perfect for continuous heavy loads or emergency backup; 110% overload for 1 hour starts big motors without tripping.
Fuel Consumption: ~205–215 g/kWh @ 100% Load	Only 55–75 L/hour full load; 10–15% cheaper to run than modern electronic engines in real-world dirty-fuel conditions.
Mechanical PT Fuel Pump & RSV Governor	Zero electronic failures; adjusts itself — keeps running even if voltage drops or dust clogs sensors.
Brushless Alternator (Stamford PI734 Series, Class H)	≤ ±1% voltage regulation, <3% THF, ≤6-second recovery; clean power for sensitive loads with zero brush maintenance.
250–500 Hour Service Intervals	Half the stops of Tier 4 engines; 38 L oil sump, spin-on filters — change oil in 20 minutes on site.
No Aftertreatment – EPA Tier 1 / China I	No DPF, no SCR, no DEF, no regen downtime; runs forever on high-sulfur diesel anywhere on earth.
Open-Type: ~3,500 × 1,200 × 1,900 mm, ~2,800 kg	Fits any truck or container; drop-in replacement for old sets — no new foundation needed.
Soundproof Canopy Option (~70–75 dB(A) @ 7m)	Hospital-grade quiet; critical-grade silencer and 60 mm rock-wool keep neighbours happy.
24V Heavy-Duty Starting System	Starts at –30 °C with optional block heater; dual 200 Ah batteries for 100 % reliability in arctic or desert.
Simple Mechanical Controls + Optional Deep Sea Panel	Auto start/stop, fault lights, remote GSM alerts; no laptop needed for basic operation.
ATS & Paralleling Ready	Seamless mains failover; sync up to 32 sets for 10 MW+ plants.
50°C Ambient Rating, Tropical Radiator	Full power in Sahara or Amazon; no derate, no extra cooling packages.
Cummins Global Warranty & Support	2-year unlimited-hour warranty, parts in 24–48 hrs on every continent — lowest lifetime cost on the market.
