The 810kW 1012kVA Cummins Industrial Generator Set C1000D5 KTA38-G5 gives factories, hospitals, utilities, mining sites, commercial buildings, and data centers a 50Hz diesel generator set with 850kW standby capacity for critical backup power.
The 1062kVA standby rating gives about 5% reserve above the 1012kVA prime rating, helping support controlled load recovery, UPS recharge, pump loads, and transfer events in facilities where the running load is close to the prime rating.
The Cummins KTA38-G5 V12 engine uses a 37.8 L displacement platform with 159 mm x 159 mm bore and stroke, giving 810kW generator set buyers a large-displacement engine base for load acceptance and stable voltage recovery.
Full-prime fuel consumption of 207 L/h equals about 0.256 L/kWh at 810kW, 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 7.8 square meters, with a 4374 mm package length that supports compact plant-room installation and leaves more service space around the skid.
The PowerBox 20S / 20ft ISO silent type configuration measures 6058 x 2438 x 2591 mm, giving outdoor projects acoustic treatment and weather protection without the footprint of a 40ft container.
PowerCommand 3.3 control with a DSE7420 MKII alternative gives project teams practical choices for automatic start, alarms, event monitoring, protection, and high-power diesel generator supervision.
Compared with typical same-power-class diesel generator sets, the C1000D5 combines a Cummins 38-liter engine platform, compact open dimensions, a 20ft ISO acoustic option, and global Cummins service support for lower procurement and maintenance risk.
