| Configuration | 6 cylinders, vertical inline, four-stroke | Designed for stationary electric-power generation. |
| Displacement | 15.2 L (927.6 in³) | Commonly referred to as the Perkins 15-litre platform. |
| Bore × stroke | 137 × 171 mm | Internal components still require Build List and ESN verification. |
| Compression ratio | 16.0:1 | Do not use compression ratio alone to identify overhaul parts. |
| Aspiration | Turbocharged and air-to-air charge cooled | Cooling performance must suit altitude, ambient temperature and enclosure airflow. |
| Combustion | Direct injection | Fuel-system components must match the approved engine record. |
| Fuel control | Mechanically actuated unit injectors with full-authority electronic control | ECM calibration, injectors, sensors and harness must match the rating. |
| Rated speed on this page | 1500 rpm | Configured for 50 Hz generator-set operation. |
| Governing | ISO 8528-5 class G3 with isochronous capability | Completed genset response also depends on controller and alternator integration. |
| Rotation | Anti-clockwise from the flywheel end | Confirm coupling and alternator arrangement before replacement. |
| Lubricating-oil capacity | Approximately 62 L | Final service quantity depends on sump and installation. |
| Coolant capacity | Approximately 58 L | The completed generator-set cooling circuit may require additional coolant. |
| Emissions position | EU 97/68/EC Stage II / U.S. EPA Tier 2 | Constant-speed emissions configuration; destination-country acceptance should still be checked. |
| Exhaust aftertreatment | None specified | Destination-country and site requirements must be checked before supply. |
1500 rpm / 50 Hz Power Output
This page covers the TAG2 1500 rpm / 50 Hz configuration. Final electrical output depends on the approved engine rating, alternator efficiency, controller settings, cooling system and site derating.
| Duty | Gross Mechanical Output | Net Mechanical Output | Typical Electrical Output | Operating Position |
|---|---|---|---|---|
| Prime | 451 kWm (approximately 605 hp) | 435 kWm (approximately 583 hp) | 400 kWe / 500 kVA | Variable-load operation with extended annual use under the applicable prime-power definition. |
| Standby | 495 kWm (approximately 664 hp) | 478 kWm (approximately 641 hp) | 440 kWe / 550 kVA | Emergency operation when the normal electrical supply fails. |
The kVA values assume a typical 0.8 power factor and approximately 92% alternator efficiency. Standby output should not be selected as a continuous base-load rating.
Prime and Standby Duty Selection
| Duty | Typical Use | Operating Limitation | Selection Risk |
|---|---|---|---|
| Prime power | Variable-load generation where the engine is a regular power source | Unlimited annual hours within the published load-factor definition; 10% overload may be available for 1 hour in every 12 hours | Do not size the set only from the maximum connected load. |
| Standby power | Emergency backup when the normal utility or primary source fails | Limited annual use under the applicable rating definition; no overload | Do not use the 550 kVA standby rating for continuous production power. |
Reference Fuel Consumption at 1500 rpm
Fuel-use figures are planning references and may vary with the approved Build List, load profile, alternator efficiency, fuel density, fan demand, ambient temperature and altitude.
| Operating Point | Approximate Fuel Use | Planning Note |
|---|---|---|
| Standby rating | Approximately 114 L/h | Use only for emergency standby calculations. |
| 100% prime load | Approximately 106 L/h | Useful for full-load fuel-tank and operating-cost planning. |
| 75% prime load | Approximately 81 L/h | Often more representative of variable-load operation. |
| 50% prime load | Approximately 55 L/h | Do not extrapolate linearly to lower loads. |
For final tank sizing, request the rating sheet for the confirmed engine and calculate against the actual hourly load profile.
ElectropaK Equipment and Installation Data

Build List and ESN Verification
The full 2506C-E15TAG2(E/U) designation identifies the engine family and TAG2 power node, but it does not define every fitted component. Treat the E/U suffix as part of the supplied engine record and use the complete Build List and ESN to verify the ECM, cooling equipment, electrical system, flywheel arrangement and replacement parts.
| Identification Item | Example | Purpose |
|---|---|---|
| Engine model | 2506C-E15TAG2(E/U) | Identifies the full model designation and TAG2 rating; retain the E/U suffix during verification. |
| Build List | MGBF8026 or MGB8026 | Identifies the production specification and fitted component combination. |
| Engine Serial Number | Complete ESN from the dataplate | Links the engine to its individual manufacturing and service record. |
| Rated speed and duty | 1500 rpm, prime or standby | Prevents selection of the wrong output or calibration. |
| Dataplate photograph | Clear image of every field | Reduces transcription errors during quotation and parts matching. |
MGBF and MGB Build List References
MGBF8026 and MGB8026 may appear as related Build List references in engine and parts records, but they should not be treated as universally interchangeable from the prefix alone. Confirm the complete Build List, ESN, E/U designation and applicable component supersessions before approving an engine or part.
1500 rpm and 1800 rpm Family Configurations
The wider 2506C-E15TAG family includes 1500 rpm and 1800 rpm products, but the official TAG2 specification covered on this page is the 1500 rpm / 50 Hz version. For a 60 Hz project, verify the correct TAG3 or TAG4 model, ECM calibration, AC alternator, voltage, cooling and controller settings instead of assuming a TAG2 dual-speed conversion.
2506A, 2506C and 2506D Compatibility
The 2506A, 2506C and 2506D variants share a common 15.2 L platform, but different emissions positions, calibrations and supplied equipment can affect complete-engine and component compatibility.
| Compatibility Check | Items to Compare |
|---|---|
| Mechanical interface | Mounts, flywheel, housing, coupling, dimensions and alternator alignment |
| Electrical interface | ECM, harness, starter voltage, charging alternator, sensors and controller connections |
| Rating | 1500 rpm, 50 Hz, prime or standby duty and ECM calibration |
| Cooling | Radiator, charge cooler, fan, enclosure airflow and ambient capability |
| Emissions position | Fuel Optimised, EU Stage II / U.S. EPA Tier 2 or Tier 3 requirements and destination-market acceptance |
| Parts | Build List, ESN, existing part number and current supersession |
Any A-to-C, C-to-D or D-to-A replacement should be handled as an engineering substitution rather than a direct model-name replacement.
