M1308 Series: 470-545 kW

Prime kW ratings for 3Ø at 0.8 power factor. Consult factory for deration factors.
Net flywheel hp rating for fully equipped engine at rated speed under SAE J816b.
Based on prime kW rating at 1800 and 1500 RPM. Fuel rate may vary depending on operating conditions.
Data for units with hydrolastic mounts, heat exchanger cooling and 3 phase generator ends. Dimensions and weight are affected by optional equipment, AC output, phase, exhaust and cooling configuration.
Consult factory for data on enclosures for sets with InSep.

Dimensions and weights are subject to change without notice, they are not intended for installations.
