250 kVA generator · UAE, KSA & Iraq
A 250 kVA generator delivers about 200 kW at 0.8 power factor — the right size for schools, supermarkets, mid-size buildings, cold stores, pump stations and construction sites. We supply it with Cummins, Perkins, Volvo Penta or Baudouin engines from our Sharjah warehouse, with a matched ATS panel and a 1-year warranty.

A 250 kVA set typically powers schools, supermarkets, mid-size buildings, cold stores, pump stations and construction sites.
Check the largest motor or chiller start: in this range the starting kVA often decides the size more than the running load.

250 kVA generator
About 200 kW of running load at 0.8 power factor. Keep 20–25 % headroom for motor starting and Gulf heat — in practice roughly 160 kW continuous, for example around 66 split AC units of 2 tons, or the equivalent mix of lighting, pumps and equipment.
Roughly 28 L/h at 50 % load, 39 L/h at 75 % and 54 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 361 A, so a 400 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 (250 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 227 kVA for this set) or choose the next size up.
