The 823kW 1029kVA Cummins Industrial Generator Set C1100D5B KTA38-G14 gives factories, hospitals, utilities, mining sites, commercial buildings, and data centers a 50Hz diesel generator set with 906kW standby capacity for critical backup power.
The 1132kVA standby rating gives about 10% reserve above the 1029kVA prime rating, helping support pump inrush, motor starting, UPS recharge, and load recovery after automatic transfer events.
The Cummins KTA38-G14 V12 engine uses a 37.8 L displacement platform with 159 mm x 159 mm bore and stroke, giving 823kW generator set buyers a large-displacement engine base for load acceptance and stable voltage recovery.
Full-prime fuel consumption of 208 L/h equals about 0.253 L/kWh at 823kW, 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 8.0 square meters, with a 4470 mm package length that supports compact plant-room installation and leaves more room for maintenance access around the skid.
The enclosed silent type configuration measures 6500 x 2350 x 2902 mm, giving outdoor projects weather protection and acoustic treatment without moving into a full 40ft container footprint.
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 C1100D5B combines a Cummins 38-liter engine platform, 10% standby reserve, compact open dimensions, and global Cummins service support for lower procurement and maintenance risk.
