1250 kVA generator
About 1,000 kW of running load at 0.8 power factor. Keep 20–25 % headroom for motor starting and Gulf heat — in practice roughly 800 kW continuous, for example around 333 split AC units of 2 tons, or the equivalent mix of lighting, pumps and equipment.
Roughly 140 L/h at 50 % load, 195 L/h at 75 % and 270 L/h at full load. Exact figures depend on the engine model; we include the manufacturer's fuel curve with every quotation.
Full-load current at 400 V three-phase is about 1,804 A, so a 2000 A ATS is the usual match — or the main incoming breaker rating if that is larger. A 4-pole ATS is recommended where the generator neutral is separately earthed.
It depends on the engine brand, enclosure, controller and whether you need an ATS and fuel tank. Send us the site and delivery city on WhatsApp and we reply the same working day with 2–3 engine options side by side.
Standby (1250 kVA) is for emergency backup with limited annual hours. If the set is your main power — a construction site or an area with daily outages — size on the prime rating (about 1136 kVA for this set) or choose the next size up.
