The JCB G545QX 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 505 kVA (404 kW) and a standby rating of 552 kVA (441.6 kW) at 50 Hz, the G545QX 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 (02-14) six-cylinder diesel engine with a 12.70-litre displacement. The engine uses direct fuel injection and turbocharged-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 features an electronic governor for accurate engine-speed and frequency control.

The G545QX is equipped with a robust four-pole alternator featuring star-connected windings, Class H insulation, IP23 enclosure SSSSSSSSprotection, self-excited brushless excitation, and electronic AVR voltage regulation. The alternator provides stable electrical output with ±1% steady-state voltage regulation. The standard configuration operates at 400/230 V, 50 Hz, three phase, with a 0.8 power factor.

The QX configuration is designed as a durable acoustic canopy package for demanding fixed-site and industrial applications. The G545QX has a published standard fuel tank capacity of 740 litres, with a larger 2,090-litre fuel tank option available. The canopy dimensions are approximately 4500 × 1800 × 2340 mm, with a weight including oil and water of approximately 4757 kg.

The G545QX is designed for applications where substantial prime or standby power is required for extended periods. Its combination of a Scania six-cylinder engine, fuel-optimised configuration, robust alternator, electronic engine control, and acoustic QX canopy makes it suitable for demanding commercial and industrial power-generation requirements.With its 505 kVA prime rating, 552 kVA standby rating, Scania DC13-72A engine, 12.70-litre displacement, turbocharged-aftercooled technology, 400 V three-phase output, and fuel-optimised QX configuration, the JCB G545QX provides a dependable high-capacity power-generation solution.
