The 328kW 410kVA Cummins Industrial Generator Set C450D5 QSG12-G4 gives factories, hospitals, commercial buildings, water treatment plants, rental fleets, telecom sites, and construction projects a 50Hz diesel generator set with 360kW standby capacity.
The 450kVA standby rating gives about 9.8% reserve above the 410kVA prime rating, helping support pump inrush, compressor starts, lift motors, UPS recharge, and load recovery after transfer events.
The Cummins QSG12-G4 inline 6-cylinder engine uses an 11.8 L displacement platform with 132 mm x 144 mm bore and stroke, giving 360kW generator buyers a compact heavy-duty engine base for load acceptance.
Full-prime fuel consumption of 82 L/h equals about 0.250 L/kWh at 328kW, giving procurement teams a clear diesel storage and operating-cost benchmark for same-power-class generator set comparisons.
The open type generator set footprint is about 4.1 square meters, with a 3686 mm package length that supports compact plant-room installation and easier service access around the skid.
The sound attenuated configuration at 5092 x 1564 x 2375 mm supports outdoor installation, weather protection, and lower site noise for commercial facilities, hospitals, utilities, and remote industrial sites.
PowerCommand 2.2 control with a DSE7320 MKII alternative gives project teams practical choices for automatic start, alarms, event monitoring, protection, and industrial diesel generator supervision.
Compared with typical same-power-class diesel generator sets, the C450D5 combines a Cummins 12-liter engine platform, nearly 10% standby reserve, compact open dimensions, and global Cummins service support for lower procurement and maintenance risk.
