Browse Store Large electrical projects often require more than finding a transformer with the right kVA rating. Primary and secondary voltage, switchboard capacity, breaker distribution, enclosure type and the requirements of the downstream load all have to work together.
EMSCO currently stocks a 2600 kVA medium-voltage transformer paired with a 4000A Eaton Pow-R-Line switchboard . This type of package may be worth considering for industrial facilities, data centers, cryptocurrency mining operations and other projects with large, concentrated electrical loads.
But the equipment has to match the application. Before purchasing a transformer and switchboard package, here are the specifications and some of the most important items to verify.
2600 kVA Transformer Specifications
The available DB three-phase, pad-mounted transformer is configured with:
- Capacity: 2600 kVA
- Primary voltage: 34,500V Delta
- Secondary voltage: 416Y/240V
- Phase: 3-phase
- BIL: 150 kV
- Fluid: FR3, approximately 537 gallons
- Windings: Aluminum
- Installation: Pad-mounted, outdoor
- High-voltage loadbreak switch: 35 kV, 300A
- Deadbreak high-voltage bushing: 35 kV, 600A
- Protection: Bayonet fuse and current-limiting fuse
The transformer also includes multiple primary-voltage tap settings. Exact serial numbers, impedance and other unit-specific information may vary, so confirm the specifications of the available unit before designing around it.

4000A Eaton Pow-R-Line Switchboard Specifications
The matching Eaton Pow-R-Line PRL-C switchboard is configured with:
- Main rating: 4000A
- Voltage: 415/240V
- Phase: 3-phase
- Wire: 4-wire
- Main breaker: Eaton Magnum SB insulated-case breaker
- Operation: Electrically operated, 110-125 VAC motor operator
- Protection: LSIG trip functions with ground fault
- Arc-flash reduction: Equipped with arc-flash reduction setting
- Distribution: (48) HFD3080 80A, 3-pole breakers
- Enclosure: NEMA 3R outdoor
- Approximate dimensions: 164 in. W × 62 in. D × 91 in. H
If this configuration does not match your project, EMSCO also stocks additional low-voltage switchgear and switchboards in a range of amperages, voltages and configurations.
What Should You Check Before Buying?
A 2600 kVA rating and 4000A main are only part of the specification. Contractors, engineers and facility teams should verify the complete electrical requirements of the project before purchasing.
1. Confirm the Available Primary Voltage
This transformer has a 34.5 kV primary. The available utility or facility distribution voltage must be compatible with the transformer and the planned installation.
Do not start with kVA alone. Start with the power available at the site and the voltage required by the load.
2. Confirm the Required Secondary Voltage
The transformer is configured for a 416Y/240V secondary, while the Eaton switchboard is rated 415/240V, 3-phase, 4-wire.
Verify that the voltage configuration is appropriate for the switchboard, downstream distribution equipment and connected loads. The final electrical system should be reviewed by the appropriate qualified electrical professionals.
3. Calculate the Required Capacity
A 2600 kVA transformer is intended for substantial electrical loads. Proper transformer sizing depends on more than the connected load at a single point in time. Continuous loading, demand, future expansion and other design requirements may affect the required capacity.
An oversized transformer is not automatically the better choice. The equipment should be sized for the actual system and application.
4. Review the Breaker Distribution
The switchboard's 48 80A, 3-pole HFD3080 breakers are an important part of this particular configuration. A 4000A switchboard may have the right main rating while still having the wrong downstream distribution for a project.
Before purchasing, determine how many downstream circuits are required, what breaker sizes are needed and whether the existing distribution matches the planned loads.
5. Confirm the Installation Environment
The transformer is pad-mounted for outdoor installation, and the switchboard uses a NEMA 3R outdoor enclosure.
Site conditions, equipment clearances, foundations, cable or conduit entry, environmental requirements and applicable codes should all be considered before installation.
6. Verify Protection and System Compatibility
Available fault current, interrupting ratings, grounding, conductors, transformer protection and upstream and downstream protective devices must work together as a complete electrical system.
For large power-distribution projects, those requirements should be confirmed before the equipment is purchased rather than after it arrives on site.
What Applications Could Use a Package Like This?
Transformer and switchboard packages in this capacity range may be considered for projects with large or concentrated electrical loads, including:
- Industrial facilities and manufacturing expansions
- Data centers and high-density computing facilities
- Cryptocurrency and Bitcoin mining operations
- Large commercial or industrial construction projects
- Facility expansions requiring additional distribution capacity
- Other high-load applications requiring medium-voltage transformation and low-voltage distribution
The application itself does not determine whether this equipment is a fit. Voltage, capacity, distribution, protection and the requirements of the connected loads do.
Can This Transformer and Switchboard Be Used for Bitcoin Mining?
Potentially, but Bitcoin mining is only one possible application for this equipment.
Mining facilities can create large, concentrated electrical loads, which makes transformer capacity and low-voltage distribution especially important. This package provides 2600 kVA of transformer capacity along with a 4000A switchboard and multiple 80A three-pole distribution breakers.
That does not mean it is automatically the right configuration for every mining project. Available utility voltage, mining equipment voltage, load calculations, distribution design, protection and site conditions all need to be verified first.
Why Source a Transformer and Switchboard Together?
Large electrical projects can turn into sourcing problems when the transformer is available but the required switchboard is not—or when normal manufacturer lead times do not fit the project schedule.
EMSCO maintains a large inventory of used, surplus, obsolete and professionally reconditioned industrial electrical equipment. When compatible equipment is already available, sourcing major components from the same supplier can simplify the search and help reduce the time spent locating individual pieces.
The EMSCO website does not always reflect everything currently in the warehouse. If this exact package is not the right fit, send us the requirements. We may have another transformer, switchboard or configuration available.
What Information Should You Send EMSCO?
The more information you have, the faster we can check the equipment against your requirements. Useful project information includes:
- Required transformer kVA
- Primary voltage
- Required secondary voltage
- Phase and wire configuration
- Switchboard amperage
- Main breaker or main-device requirements
- Required branch breaker sizes and quantities
- Indoor or outdoor installation
- Nameplate photos
- One-line diagrams, drawings or equipment schedules
- Required project or shipment date
Availability, condition, exact configuration, serial numbers and testing documentation should be confirmed for the specific equipment being quoted.
