Cummins N855 50 Hz genset delivers stable and robust power for factories, workshops, marine-support vessels, and commercial sites. Its 6-cylinder inline diesel engine (about 14 L) handles continuous loads reliably and adapts smoothly to changing demand.
The alternator uses a brushless, three-phase design with low-reactance 2/3-pitch winding and class-H insulation. It keeps voltage stable and waveform clean — even with heavy or mixed loads — and supports smooth motor starts.
A built-in radiator and fan cooling system keeps engine temperature steady during long runtimes or variable load conditions. The integrated cooling simplifies installation and promotes consistent performance.
The control system offers automatic start/stop, accurate frequency and voltage regulation, output monitoring, alarm alerts, and protective shutdown when needed. These features make operation and maintenance simple and reliable.
With its strong engine, dependable alternator, and stable cooling and control systems, the N855 genset provides a practical, cost-effective 50 Hz power solution — whether for continuous industrial power, marine support, or emergency backup.
