JJP-M300GF — 375 kVA / 300 kW prime, 413 kVA / 330 kW standby. 541 A per phase at 400 V, 3100 × 1350 × 1850 mm, 1900 kg, 67.2 L/h at full load. FOB China US$20,000–28,000.
See the Full Specification375 kVA is the prime rating on the nameplate, not a rounded-up figure — the frame maps exactly onto the requirement. 1500 rpm at 50 Hz, 1800 rpm at 60 Hz, three-phase four-wire, 0.8 power factor.
| Voltage | Phase | Current at 375 kVA | Suggested breaker frame |
|---|---|---|---|
| 380 V | 3-phase | 570 A | 700 A |
| 400 V | 3-phase | 541 A | 700 A |
| 415 V | 3-phase | 522 A | 630 A |
| 440 V | 3-phase | 492 A | 630 A |
| 480 V | 3-phase | 451 A | 630 A |
| 220 V | 1-phase | 1705 A | special winding |
| 240 V | 1-phase | 1562 A | special winding |
I = kVA × 1000 ÷ (√3 × V). Breaker sizing at 125% of the 400 V figure gives 676 A. Cable at 541 A needs roughly 2 × 120 mm² copper per phase for a run under 50 m. A single-phase 375 kVA set would need a bespoke alternator — balance the load across three phases instead.
| Configuration | L × W × H | Weight |
|---|---|---|
| Open skid | 3100 × 1350 × 1850 mm | 1900 kg |
| Silent canopy | 3700 × 1950 × 2450 mm | 2080–2150 kg |
| With full baseframe tank | — | +250–400 kg depending on tank size |
At 1900 kg the open set lifts with a forklift; the canopied version needs a crane or a heavy forklift. Allow 1 m clearance at the alternator end for cooling air and confirm canopy door swing on both long sides before siting. Cast a level concrete plinth rated for 1.5× the wet weight.
| Load | Diesel L/h | US gal/h |
|---|---|---|
| 375 kVA / 300 kW (100%) | 67.2 L/h | 17.7 |
| 300 kVA / 240 kW | 53.7 L/h | 14.2 |
| 225 kVA / 180 kW | 40.3 L/h | 10.6 |
| 150 kVA / 120 kW | 26.9 L/h | 7.1 |
| 75 kVA / 60 kW | 13.4 L/h | 3.5 |
Based on ≤187 g/kWh at 835 g/L diesel density — about 0.179 L per kVA per hour at rated load. Consumption tracks load almost linearly in this class, so a set held at 50% for 12 hours a day burns roughly half the full-load figure for twice as long: the fuel bill per kWh barely changes, but the engine runs cleaner.
| Brand | Engine model | Standby output | Cylinders | Displacement |
|---|---|---|---|---|
| Weichai | WP12D353E200 | 353 kW | 6-cyl | 11.6 L |
| SDEC | E-series | 330 kW | 6-cyl | 12 L |
| Perkins | 2206A-E13TAG2 | 330 kW | 6-cyl | 13 L |
| Volvo | TAD733GE | 313 kW | 6-cyl | 7.2 L |
| Yuchai | YC6M400-D20 | 294 kW | 6-cyl | 10.3 L |
Coupled to a Faraday FD4M-4 or Stamford HCI444 alternator, with a Deep Sea DSE7320 MKII controller as standard and DSE8610 for parallel operation. At 375 kVA the engine choice moves both price and serviceability — Cummins and Perkins have the widest parts network in Africa and the Middle East; Weichai and SDEC are the cost-competitive options with strong regional support; Volvo suits projects with emission or brand requirements. Note the Yuchai standby output: confirm the derate before specifying it for a continuous load.
Open-skid JJP-M300GF sets run US$20,000–28,000 FOB China. Engine brand moves that band more than anything else — Cummins and Perkins sit at the top, Weichai and SDEC at the bottom. A sound-attenuated canopy adds 8–12% and about 200 kg. Budget separately for a 700 A breaker, an ATS if the site needs automatic transfer, a synchronising panel if two sets run in parallel, and freight. Local market prices in India, Pakistan, Nigeria and South Africa usually run 40–80% above FOB once duty, inland freight and dealer margin are added — compare like for like before quoting a landed figure.
541 A per phase at 400 V three-phase, 570 A at 380 V, 522 A at 415 V, 451 A at 480 V. Size the breaker at 125% of the 400 V figure.
1900 kg on an open skid, 3100 × 1350 × 1850 mm. The silent canopy adds 180–250 kg and 300 mm per dimension, giving about 2080–2150 kg before fuel.
67.2 L/h at full 375 kVA load, 40.3 L/h at 50% load. That is 0.179 L per kVA per hour — consumption is close to linear with load in this class.
At 0.8 power factor, yes — 375 × 0.8 = 300 kW. A lower site power factor reduces the usable kW further, so check the PF before confirming the rating.
Yes, with the DSE8610 controller, matching alternator pitch and a synchronising panel. Two sets give 750 kVA total, or N+1 redundancy at 375 kVA. Specify it at the quote stage — retro-fitting is expensive.
Cummins and Perkins for parts availability across Africa and the Middle East; Weichai and SDEC for cost with strong regional support; Volvo where emissions or brand specification matter; Yuchai only where its lower standby output still clears the load.
65–75 dB(A) at 7 m for the canopied set, depending on acoustic grade. Residential-grade units sit at the low end; standard export canopies at the high end.
Three-phase is standard at this rating. A single-phase 375 kVA set needs a specially wound alternator and is rarely economic above 50 kVA — split the load across three phases instead.
Running kW, largest motor, duty and destination port — we will confirm the engine option, the tank size and the canopy grade, and price it landed-ready.
