The 288kW 360kVA Cummins Industrial Generator Set C400D5 QSG12-G3 gives factories, hospitals, water treatment plants, logistics parks, commercial buildings, and rental fleets a 50Hz diesel generator set with 320kW standby capacity.
The 400kVA standby rating gives about 11.111% reserve above the 360kVA prime rating, helping support motor starting, transfer recovery, pump loads, UPS recharge, and short emergency peaks.
The Cummins QSG12-G3 engine uses a 6L, 11.8 L diesel platform, giving buyers a proven engine base with broad parts availability and service support.
Full-prime fuel consumption of 72 L/h equals about 0.25 l/kwh at 288kw, giving procurement teams a practical diesel storage and operating-cost benchmark for same-power-class generator set comparisons.
The open type generator set footprint is about 4.055 square meters, supporting plant-room installation, service access, and easier transport planning before site work starts.
The silent type generator set package at 5093 x 1564 x 2375 mm supports outdoor standby power projects where acoustic treatment, weather protection, and maintenance access are required.
PowerCommand control with a DeepSea alternative supports auto-start, alarms, shutdown protection, event monitoring, and practical daily operation for industrial diesel generator set users.
Compared with typical same-power-class diesel generator sets, this Cummins generator set combines a clear prime/standby rating, a serviceable footprint, established engine support, and flexible open or silent configuration choices.
