Import Cummins Diesel Generator 4bt3.9 — Buy in Bulk from Supplier in China

The Cummins Diesel Generator 4bt3.9 is a compact, reliable power solution built around the Cummins 4B3.9 engine, a globally recognised series designed for industrial and standby applications. This model delivers a rated output in the 25 kVA to 80 kVA range, dependent on configuration, and is engineered for durability in demanding environments such as telecom sites, construction projects, and emergency backup systems. The generator set integrates a robust alternator, automatic voltage regulation, and a control panel compatible with remote monitoring, ensuring stable performance under variable loads.

Constructed with a cast-iron engine block and forged steel crankshaft, the 4B3.9 engine is known for its longevity and low vibration, a standard feature in Cummins’ mid-range diesel engines. Typical fuel consumption for this engine class is 210 to 230 g/kWh at 100 percent load, with a standard operating speed of 1500 RPM for 50 Hz power generation. The unit is designed to run on diesel fuel meeting EN 590 or ASTM D975 standards, and the alternator usually conforms to IP23 protection, a common rating for industrial generators.

Industries such as telecommunications, healthcare, and oil and gas rely on the 4bt3.9 for its quick start-up and consistent power delivery in remote or off-grid locations. Buyers typically source this model for primary or standby power, with common configurations including sound-attenuated enclosures for noise-sensitive areas and open-frame designs for ventilation and maintenance access. The generator’s modular design allows for integration with automatic transfer switches and parallel operation setups, making it adaptable to complex power systems.
