Diesel generator set NT855 series engine
320 kVA–440 kVA 50 Hz 320 kW–400 kW 60 Hz
Description
This Cummins® Power Generation commercial generator set is a fully integrated power generation system, providing optimum performance, reliability, and versatility for stationary standby, prime power, and continuous duty applications. Cooling system – Standard integral setmounted radiator system, designed and tested for rated ambient temperatures, simplifies facility design requirements for rejected heat. Control system – Standard PowerCommand® electronic control provides total system integration including remote start/stop, precise frequency and voltage regulation, alarm and status message display, AmpSentry protection, output metering, auto-shutdown. Enclosures – Optional weather-protective and sound-attenuated enclosures are available. Warranty – Backed by a comprehensive warranty and Worldwide distributor network.
Features
Cummins® heavy-duty engine – Rugged 4-cycle industrial diesel delivers reliable power, low emissions and fast response to load changes. Permanent magnet generator (PMG) – Offers enhanced motor starting and fault clearing short circuit capability. Alternator – Several alternator sizes offer selectable motor starting capability with low reactance 2/3 pitch windings; low waveform distortion with non-linear loads, fault clearing short-circuits capability, and class H insulation.
