The JCB G440QX diesel generator set is designed to provide reliable, efficient, and consistent electrical power for demanding commercial, industrial, construction, infrastructure, rental, and standby applications. With a prime rating of 400 kVA (320 kW) and a standby rating of 450 kVA (360 kW) at 50 Hz, the G440QX is suitable for manufacturing facilities, commercial buildings, construction projects, warehouses, infrastructure developments, data and communication facilities, and other applications requiring dependable high-capacity power.

The genset is powered by a Scania DC13-72A diesel engine featuring a 12.7-litre displacement and a robust six-cylinder configuration. The engine uses direct fuel injection together with turbocharged and aftercooled aspiration, providing efficient combustion, strong load response, and consistent power delivery under varying operating conditions. The engine operates at 1500 rpm at 50 Hz and incorporates an electronic governor for precise engine-speed and frequency control.

The G440QX is equipped with a robust four-pole alternator designed for stable electrical output and dependable operation under demanding loads. The generator operates at 400/230 V, 50 Hz, three phase, with a 0.8 power factor. The QX configuration provides a durable acoustic canopy package designed for demanding site environments while maintaining practical access for servicing and maintenance.

The G440QX uses a 740-litre standard fuel tank, with larger fuel-tank options available for extended operating periods. The published QX specification gives the canopy dimensions as approximately 4500 × 1800 × 2340 mm, while the weight including oil and water is approximately 4524 kg.

The JCB QX range is designed for applications where high-capacity prime or standby power is required. Its combination of a Scania engine, efficient fuel system, robust alternator, electronic engine control, and acoustic canopy makes the G440QX suitable for demanding commercial and industrial power-generation applications.With its 400 kVA prime rating, 450 kVA standby rating, Scania DC13-72A six-cylinder engine, 12.7-litre displacement, turbocharged-aftercooled technology, 400 V three-phase output, and fuel-optimised QX configuration, the JCB G440QX provides a dependable high-capacity power-generation solution.
