Notes

  1. Prime kW ratings for 3Ø at 0.8 power factor. Consult factory for deration factors.
  2. Lloyd’s Register classed M1066H @ 50 Hz = 110oC temperature rise at 45oC ambient.
  3. Net flywheel hp rating for fully equipped engine at rated speed under SAE J816b.
  4. Based on prime kW rating at 1800 and 1500 RPM. Fuel rate may vary depending on operating conditions.
  5. 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.
  6. Consult factory for data on enclosures for single phase sets or sets with InSep
