The 58kW 73kVA Cummins Industrial Generator Set C80D5 6BT5.9-G1 gives commercial buildings, farms, telecom sites, rental fleets, small factories, and construction projects a 50Hz diesel generator set with 64kW standby capacity.
The 80kVA standby rating gives about 9.589% reserve above the 73kVA prime rating, helping support motor starting, transfer recovery, pump loads, UPS recharge, and short emergency peaks.
The Cummins 6BT5.9-G1 engine uses a 6L, 5.9 L diesel platform, giving buyers a proven engine base with broad parts availability and service support.
Full-prime fuel consumption of 16.3 L/h equals about 0.281 l/kwh at 58kw, 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 2.381 square meters, supporting plant-room installation, service access, and easier transport planning before site work starts.
The silent type generator set package at 2900 x 1100 x 1800 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.
