Applications
Recommended applications and package choice
The generator package and trailer chassis must be verified together
The engine and alternator determine loaded performance; axle load, brakes, drawbar, steering, supports and lighting determine safe transport and placement.

Core configuration
Four core configurations behind reliable operation
Generation and cooling
Engine, alternator and cooling are matched to loads, ambient conditions and enclosure resistance for stable starting and loaded operation across sites.
Trailer chassis and braking
Frame, drawbar, turntable or steering, axles, tires, brakes, lighting and supports determine transport and placement safety against gross weight and local road rules.
Enclosure, output and cables
Weatherproof or acoustic enclosure protects the package; terminals, sockets, quick connectors, cable length and voltage drop are selected for site loads and deployment time.
Fuel, controls and deployment
Fuel, refueling, controller, emergency stop, grounding, task lighting, monitoring and cable management determine how quickly and safely the set can start work.
Key parameters
Parameters used for project selection
These are the parameters that shape selection and interfaces. Fuel consumption, noise and dimensions are supplied after the engine model, load factor and site environment are defined.
| Reference output | 300 kW / 375 kVA @ PF 0.8 |
|---|---|
| Rating basis | Prime/standby rating confirmed against the final engine model, ISO 8528 conditions and duty |
| Engine / alternator | Cummins / Project-selected alternator |
| Trailer format | Tandem-axle trailer |
| Road / towing | Tow vehicle, gross weight, axle loads, coupling, brakes, tires, lighting and road permits confirmed by project |
| Enclosure / output | Weatherproof or acoustic enclosure; terminals, industrial sockets or quick connectors selected for loads and cables |
| Fuel autonomy | Base or extended tank sized from continuous runtime, usable volume and refueling route |
| Deployment interfaces | Leveling supports, emergency stop, grounding, task lighting, monitoring and cable management available |
