c2750 d5e generator

This Cummins® 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.

Features & Benefits

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 F or H insulation.

Cooling system - Optional remote mounted cooling system, designed and tested for rated ambient temperatures, offers maximum flexibility for facility design requirements.

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 at fault detection and NFPA 110 Level 1 compliance.

NFPA - The genset accepts full rated load in a single step in accordance with NFPA 110 for Level 1 systems. 

Warranty and service - Backed by a comprehensive warranty and worldwide distributor network.
