Ricardo 30 kW diesel generator with a listed Ricardo ZH4102D four-cylinder, water-cooled diesel engine.
Send your load list, duty and site conditions to confirm the current data sheet, 12 V charging package, ATS or enclosure options and scope of supply.
The Ricardo 30 kW diesel generator listed by Alexerpower / Weifang Junwei Machinery Co., Ltd uses a Ricardo ZH4102D four-cylinder, water-cooled diesel engine. Its published electrical ratings are 30 kW / 37.5 kVA prime power and 33 kW / 41.25 kVA standby power at 50 Hz and a power factor of 0.8. The listed engine speed is 1500 rpm.
The listing provides three-phase voltage options of 440 V, 415 V, 400 V and 380 V. Send your required voltage, load list and operating duty to confirm the generator and control package for your installation.
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 purchase.

Use the complete generator’s 30 kW prime and 33 kW standby electrical ratings when discussing loads. The 34.5 kW reference in the original mechanical section does not establish a 34.5 kW generator electrical rating. Request separate engine shaft-power and generator electrical-output data with their applicable duty definitions.
Include the required options in your enquiry and confirm compatibility and the items included in the quotation:
The existing description includes a belt-driven radiator fan with safety guard, vibration isolation, dry-type air filter, fuel filter and oil filter. Confirm the final bill of materials, installation drawing and service-access requirements.
The listing gives 30 kW / 37.5 kVA prime and 33 kW / 41.25 kVA standby at 50 Hz and a power factor of 0.8. The mechanical section also mentions 34.5 kW, whose rating basis requires confirmation. It should not replace the listed 33 kW electrical standby value. Confirm the approved duty and load profile; standby output should not be assumed suitable for continuous operation.
The published voltage options are 440 V, 415 V, 400 V or 380 V, three-phase, 50 Hz, with the engine listed at 1500 rpm. For another voltage or a 60 Hz requirement, request a separately approved engine-alternator configuration and corresponding ratings rather than reusing the 50 Hz data.
The published reference is 238 g/kW·h at the stated 100% prime power load, a specific fuel-consumption figure rather than a litres-per-hour value. Ask for the measurement basis and complete generator-set L/h data at your intended loads, with fuel specification and test conditions, before estimating fuel cost or tank capacity.
The listed maximum current of 56.98 A is not a fixed value for every voltage. Request the nameplate current for the ordered configuration and voltage/frequency performance data with load steps and test conditions. Include motors, starting sequence and sensitive equipment in the load list so the proposed alternator, governor and controller can be assessed together.
Confirm the supplied alternator’s protection rating and complete scope of supply. ATS, paralleling and enclosure formats are listed as options. For a soundproof unit, request noise data stating the enclosure type, operating load and measurement distance.
The existing listing states 12 months from the date of sale or 1000 running hours, whichever comes first. Confirm these terms in the quotation, including coverage, exclusions and service arrangements. Request manuals, a factory test report and model-specific conformity or emissions documents needed for your destination.
For site power, machinery or backup-power enquiries, provide the actual loads and operating conditions so the proposed 30 kW generator can be checked for your project:
The Cummins generator-set selection guide provides general background on ratings, load assessment and site conditions. Confirm this Ricardo assembly’s specification using its own approved data sheet.
Contact Alexerpower with your electrical load and project requirements. Ask for the current ZH4102D engine and alternator specifications, duty ratings, fuel-consumption data, installation drawing, current photographs, warranty terms and full scope of supply.
