Cummins C125D6D 125kW Agricultural Diesel Generator 120/240V Single Phase | A060A344

Cummins C125D6D 125kW Agricultural Diesel Generator

Provide dependable emergency power for critical farm equipment with the Cummins C125D6D 125kW Agricultural Diesel Generator. Cummins part number A060A344 is a factory-configured agricultural standby generator designed for farms, livestock facilities, irrigation systems, poultry houses, dairy operations, grain facilities, greenhouses and other agricultural applications that rely on 120/240-volt single-phase power.

This heavy-duty diesel generator produces 125kW of standby power at 120/240V single phase and includes a 600-amp main circuit breaker. It combines a Cummins QSB7 industrial diesel engine, a brushless four-pole alternator and PowerCommand 1.1 electronic controls in an open-skid package built for demanding agricultural environments.

125kW Standby Power for Farms and Agricultural Facilities

Modern agricultural operations depend on electricity for ventilation, refrigeration, irrigation, water systems, feeding equipment, milking equipment, lighting and environmental controls. A utility outage can quickly place livestock, crops, stored products and production schedules at risk.

The Cummins C125D6D is designed to automatically provide backup power when connected to a properly selected automatic transfer switch. Its 120/240V single-phase output makes it suitable for larger farms and rural facilities with single-phase electrical service.

Cummins QSB7 Heavy-Duty Diesel Engine

The C125D6D agricultural generator is powered by a Cummins QSB7 6.69-liter inline diesel engine. This rugged four-cycle industrial engine is engineered to provide reliable power and fast response as electrical loads change.

The cast-iron engine operates at 1,800 RPM and uses turbocharging and charge-air cooling to support dependable standby performance. A 100-amp engine-driven battery-charging alternator helps maintain the starting-battery system while the generator is operating.

• Cummins QSB7 industrial diesel engine
• 6.69-liter displacement
• Inline cast-iron construction
• Heavy-duty four-cycle design
• Turbocharged and charge-air cooled
• Liquid-cooled operation
• 1,800 RPM rated speed
• 100-amp battery-charging alternator
• Spin-on oil filter with pressure-relief valve

PowerCommand 1.1 Electronic Control System

The integrated Cummins PowerCommand 1.1 control system provides coordinated engine, alternator and generator-set management. It supports automatic operation when the generator is connected to compatible transfer equipment and provides the monitoring and protection functions required for critical standby-power applications.

PowerCommand Control Features

• Automatic remote start and stop
• Precise voltage regulation
• Precise frequency regulation
• Generator output metering
• Engine and generator status monitoring
• Alarm and operating-status messages
• Automatic shutdown when qualifying faults are detected
• Integrated generator-set protection
• Self-diagnostic capabilities
• NFPA 110 Level 1 control functionality
• Flexible generator exercise scheduling

Battle Short Mode

Battle Short Mode allows certain protective shutdowns to be overridden when maintaining power is considered more important than protecting the generator from possible damage.

This feature may be valuable in agricultural emergencies where the immediate loss of ventilation, water pumps, refrigeration, feeding systems or environmental controls could endanger livestock, crops or stored products.

Battle Short Mode must only be used by qualified personnel and in accordance with Cummins operating instructions.

Flexible Exercise Scheduling

Routine generator exercise helps confirm that the engine, alternator, controls and starting system are ready before an outage occurs. The PowerCommand control allows the exercise time, frequency and duration to be scheduled around the facility's needs.

Flexible scheduling can help reduce unnecessary noise, diesel consumption and emissions compared with a generator that exercises more often or longer than necessary.

Brushless Alternator Performance

The Cummins alternator uses a brushless, four-pole revolving-field design with low-reactance 2/3-pitch windings. This design helps provide stable voltage, low waveform distortion and the motor-starting capability needed for demanding agricultural equipment.

Alternator Features

• Brushless four-pole design
• Drip-proof revolving field
• Low-reactance 2/3-pitch windings
• Direct-coupled rotor
• Direct-drive centrifugal cooling blower
• Automatic voltage regulation
• Low waveform distortion with nonlinear loads
• Short-circuit fault-clearing capability
• Selectable motor-starting capability

Designed for Agricultural Environments

The C125D6D agricultural generator is engineered and tested for reliable operation under demanding environmental conditions. Its standard cooling package is designed for operation in ambient temperatures up to 50°C or 122°F under the applicable Cummins rating conditions.

Factory-supplied coolant heaters help support dependable starting in cold conditions when the generator is properly installed, maintained and connected to the required electrical supply.

Common Agricultural Applications

• Dairy farms and milking systems
• Poultry houses and ventilation equipment
• Livestock barns and environmental controls
• Automated feeding and watering systems
• Irrigation pumps and agricultural well systems
• Greenhouses and climate-control equipment
• Grain handling and conveyor systems
• Grain drying and storage facilities
• Produce refrigeration and cold storage
• Farm shops and equipment buildings
• Agricultural processing equipment
• Large rural properties with single-phase service
• Emergency power for critical farm infrastructure

Motor Starting and Generator Sizing

Agricultural facilities frequently use pumps, fans, compressors, augers, refrigeration equipment and other electric motors that require significantly more power during startup than during normal operation.

A generator should not be selected using running wattage alone. Proper sizing must account for motor-starting current, load sequencing, voltage drop, electrical-service configuration, elevation, ambient temperature and future equipment expansion.

A qualified generator professional or electrical engineer should complete a load and motor-starting analysis before the generator is ordered.

Open-Skid Agricultural Configuration

The Cummins A060A344 does not include an enclosure. The engine, alternator, radiator, controls and other generator components remain exposed on the open structural skid.

This generator must be installed inside a properly designed generator room, agricultural equipment building or separately purchased weather-protective enclosure. The installation must provide adequate airflow, ventilation, weather protection, exhaust routing, service clearances and protection from unauthorized access.

Do not order this model expecting a factory weather enclosure or sound-attenuated housing. Product images must be reviewed carefully because some representative Cummins images may show optional equipment or enclosed generator configurations that are not included with A060A344.

No Fuel Tank Included

A060A344 does not include an onboard, belly-mounted or sub-base diesel fuel tank. A properly sized external diesel tank or compatible separately purchased sub-base tank must be supplied as part of the installation.

The fuel-system design should account for desired runtime, fuel consumption, supply and return line sizing, maximum fuel lift, filtration, containment and all applicable fire and environmental codes.

Automatic Transfer Switch Not Included

An automatic transfer switch is not included. A properly sized transfer switch is required for automatic backup of a building or electrical service.

The transfer switch must match the facility's 120/240V single-phase service, amperage, service-entrance requirements and applicable electrical codes. Depending on the installation, a 600-amp transfer switch or a separately engineered distribution and load-management system may be required.

The generator must never be connected directly to utility-supplied wiring without approved transfer equipment.

Starting Batteries Required

The generator requires two 12-volt starting batteries rated at approximately 850 cold-cranking amps each. Starting batteries and battery cables are not included unless they are specifically listed on the final sales order.

The correct battery configuration, cable size, charger and cold-weather requirements should be confirmed during installation planning.
