Detailed Technical Specifications of 350 kVA Cummins Diesel Generator

Casing Variants, Physical Dimensions, and Fuel Tank Analysis

PT Multi Kharisma Prima engineers each generator casing option to optimize footprint efficiency, service accessibility, and field transportability. The table below outlines physical dimensions and daily fuel tank capacities for each configuration:

Key Characteristics of Premium Casing Construction

Every casing option for the 350 kVA Cummins generator is manufactured to high precision standards, ensuring maximum mechanical protection in demanding work environments:

• Open Type: Ideal for stationary indoor installations within dedicated engine rooms (power houses). Built upon a heavy-duty steel skid frame equipped with anti-vibration mountings, this design facilitates connection to exhaust silencer systems and acoustic room ventilation ducting. The integrated 400-liter base tank supports extended running periods.
• Silent Type: Engineered specifically for outdoor deployment and noise-sensitive operating environments. The canopy is constructed from heavy-gauge steel insulated with fire-retardant Soundproof Foam. Finished with electrostatic Powder Coating for resistance against corrosion and extreme weather, it suppresses noise levels down to 73–75 dBA at 7 meters. Features an integrated 450-liter daily fuel tank.
• Mobile Type: Designed for projects requiring power mobility across job sites, such as construction, mining, and rental applications. It mounts the Silent Type canopy onto a heavy-duty four-wheel trailer chassis equipped with handbrakes, leaf spring suspension, tail lights, and a standard towing bar. Includes a 450-liter fuel tank.

Engineering Features of the Cummins NTA 855 G4 Industrial Engine

The high-output Cummins NTA 855 G4 engine provides unmatched durability and power density for this 350 kVA generator set:

Massive 14.0-Liter Engine Displacement: The 6-cylinder inline engine block (140 mm bore and 152 mm stroke) yields high low-end torque. This large displacement allows the engine to absorb sudden electrical starting loads (inrush currents) when starting heavy industrial motors.

Optimized G4 High-Output Calibration: The NTA 855 G4 model uses optimized fuel injection and aftercooled air intake calibrations to produce 350 kVA / 280 kW power output while maintaining overall engine durability.

Fuel Economy: Consuming 56.00 liters per hour at 75% load and 75.00 liters per hour at 100% full load, the engine maintains a predictable fuel consumption rate for operational budgeting.

Serviceability and Global Spare Parts Support: Proven NTA 855 engine design simplifies routine service procedures. Supported by an established Cummins distribution network, maintenance components remain readily available across Indonesia.

High-Precision Alternator and Electrical Output

The industrial Cummins engine is paired with a Stamford / brushless alternator, producing clean and stable electrical power for sensitive facility equipment.

Equipped with an Automatic Voltage Regulator (AVR), the alternator maintains voltage regulation within a tight ±1% tolerance. This prevents voltage surges, sags, and harmonic distortions affecting computers, automated control systems, and machinery. The alternator features Class H thermal insulation rated up to 180°C and an IP23 protection enclosure against dust and moisture.

Digital Control Module and Automated Safety Features

Operation of the 350 kVA Cummins generator is managed by an advanced digital control panel (Deepsea / SmartGen) featuring an intuitive graphical display. The controller monitors key system parameters in real time:

• Comprehensive Electrical Parameters: Displays phase-to-phase and phase-to-neutral voltages, electrical current (Amps), frequency (Hz), power factor (Cos Phi), active power (kW), and cumulative energy consumption (kWh).
• Real-Time Engine Monitoring: Monitors oil pressure (38.6-liter oil capacity), coolant temperature, engine RPM, battery charging voltage, and cumulative running hours.
• Automatic Protection Shutdown: Protects the generator by initiating automatic shutdown upon detecting abnormal conditions such as low oil pressure, high coolant temperature, overspeed, battery charging failure, or electrical overload.
• ATS/AMF Integration: Ready for connection with Automatic Transfer Switch (ATS) / Automatic Mains Failure (AMF) panels to automatically start the generator during main grid power failures and transfer electrical loads.

Standard Package Inclusions

Every 350 kVA Cummins generator purchased from PT Multi Kharisma Prima is supplied as a complete operational package including standard industrial accessories:

• Complete integrated generator unit with Cummins NTA 855 G4 engine and Stamford alternator.
• Digital control panel module mounted to the generator frame.

Quality Testing and Factory Acceptance Testing

PT Multi Kharisma Prima enforces quality assurance protocols prior to shipment. Every generator set undergoes a Factory Acceptance Load Bank Test across 25%, 50%, 75%, 100%, and 110% load steps.

This procedure verifies radiator cooling performance, fuel combustion efficiency, governor speed response, and alternator voltage stability against factory specifications before site delivery.
