Ricardo 250 kW diesel generator, listed as JWR250GF with a Ricardo JW10D288B engine.
Send your load list, duty and site conditions to confirm the current data sheet, ATS, paralleling or enclosure options and complete scope of supply.
The Ricardo 250 kW diesel generator listed by Alexerpower / Weifang Junwei Machinery Co., Ltd is model JWR250GF with a Ricardo JW10D288B diesel engine. Its published 50 Hz electrical ratings are 250 kW / 312.5 kVA prime power and 275 kW / 343.75 kVA standby power, at a power factor of 0.8 and a listed engine speed of 1500 rpm.
Specify the required operating duty, voltage, phases and load profile when requesting a configuration. The prime and standby values describe different duty ratings; the standby output should not be assumed available for continuous operation.
These reference data are reorganized from the existing Alexerpower product listing. Request the current generator-set, engine and alternator data sheets, rating conditions and agreed scope of supply before ordering.

Request the JW10D288B engine’s current displacement, bore and stroke, installation dimensions and shaft-power rating from the actual supplied-model data sheet. The complete generator’s electrical rating should be assessed separately from the engine shaft-power specification.
The existing listing includes the following options for enquiry. Confirm the proposed equipment, compatibility and inclusion in the quotation:
The base description includes a belt-driven radiator fan with safety guard, vibration isolation, dry-type air filter, fuel filter and oil filter. Ask for the complete bill of materials, installation drawing and access requirements.
The listing gives 250 kW / 312.5 kVA prime and 275 kW / 343.75 kVA standby at 50 Hz and a power factor of 0.8. Confirm the approved duty definition, load profile, site conditions and operating limits for the quoted unit. Do not treat the standby rating as a continuous output.
Do not assume overload permission from the prime power label alone. Request the manufacturer’s approved overload capacity, duration, duty conditions and protection settings for the complete unit. Motor starting and load-step requirements should be assessed using generator performance data.
The published voltage options are 440 V, 415 V, 400 V or 380 V at 50 Hz. Confirm voltage and phases for the ordered unit. For 60 Hz or another voltage, request a separately approved engine-alternator configuration and corresponding ratings rather than applying the listed 50 Hz values unchanged.
The current product information does not provide a verified L/h fuel-consumption curve. Ask for complete generator-set consumption at your intended load points, with fuel specification and test conditions. Use that data and your operating schedule to discuss operating cost and the fuel-system requirements.
These are listed as options, so confirm the actual scope of supply. For ATS or paralleling, specify the operating sequence and required functions. For an enclosure, request noise data with the load, enclosure type and measurement distance stated.
Request written warranty terms with a clear start date, time and running-hour limits, coverage and exclusions. Ask for manuals, a factory test report and model-specific conformity or emissions documents required for your destination, together with the agreed spare-parts and service arrangements.
For industrial power or backup-power projects, provide the actual load and site data so the proposed 250 kW generator and control package can be assessed together:
The Cummins generator-set selection guide provides general background on duty ratings, load assessment and site conditions. Confirm this Ricardo assembly’s specification using its own approved data sheet.
Contact Alexerpower with your load list and project requirements. Request the current JWR250GF and JW10D288B data sheets, alternator and control details, electrical duty ratings, fuel-consumption data, installation drawing, current photographs, warranty terms and full scope of supply.
