Eaton T20P11B25CUESNV Transformer DS-3 - 25 kVA, Copper Windings
Part Number: T20P11B25CUESNV
Quick Summary
Eaton T20P11B25CUESNV transformer provides reliable dry-type power distribution for industrial facilities. Engineers often face bulky, hard-to-service transformers that consume floor space and complicate maintenance. The design includes copper windings, an electrostatic shield, and a rugged 819N frame to withstand demanding environments. Certifications are listed as Contact Manufacturer; for global deployments confirm CE, UL, and regional approvals. With a 25 kVA rating and 240/480 V primary feeding 120/240 V secondaries at 60 Hz, this transformer delivers stable voltage to sensitive equipment while supporting tight load regulation. The result is improved reliability, predictable downtime, and lower lifecycle costs for productive operations.

The T20P11B25CUESNV leverages a 25 kVA dry-type DS-3 design to deliver safe, low-maintenance power distribution in industrial settings, reducing total cost of ownership through longer service intervals and fewer cooling requirements. Copper windings provide high electrical conductivity, improving efficiency and minimizing I2R losses while an electrostatic shield mitigates EMI/EMC concerns for sensitive control electronics. The unit supports 240/480 V primary and 120/240 V secondary voltages at 60 Hz, enabling flexible integration with common facility power. Tap settings—1 at +5% FCAN, 2 at -5% FCBN, 2 at +2.5% FCAN, 4 at -2.5% FCBN—offer robust voltage regulation across variable loads, reducing equipment downtime and preserving process accuracy. The 80 °C rise rating enables reliable operation in typical plant environments, while the 819N frame, dimensions (23.84 in L × 24.22 in W × 42.03 in H), and 609 lb weight support straightforward installation and replacement. Warranty coverage of one year from installation or 18 months from shipment adds risk protection for procurement teams. Compatibility with standard switchgear and control-room layouts accelerates commissioning and minimizes retrofit costs, delivering faster ROI and predictable performance in factories, data centers, and process facilities.

FAQs
The T20P11B25CUESNV is designed for industrial electrical rooms, switchgear feeders, and control panel cabinets. Its DS-3 dry-type construction and 25 kVA rating suit medium‑duty distribution, where space efficiency and straightforward mounting are important. It integrates with standard 240/480 V plant supplies to deliver 120/240 V to downstream equipment, enabling reliable operation of motors, sensors, and drives in manufacturing, packaging, and process facilities.
Primary voltage is 240 V or 480 V, with secondary 120/240 V. The transformer offers taps at 1 at +5% FCAN, 2 at -5% FCBN, 2 at +2.5% FCAN, and 4 at -2.5% FCBN to aid voltage regulation under fluctuating input conditions. This facilitates stable output for critical loads and helps maintain process accuracy without additional external regulation equipment.
Copper windings provide superior conductivity, reducing I2R losses and improving efficiency. The electrostatic shield minimizes EMI/RFI coupling to adjacent circuitry, protecting sensitive controls and PLCs. Together, these features enhance reliability, enable tighter voltage regulation, and support compliant operation in environments with electrical noise and sensitive instrumentation.
Certifications are listed as 'Contact Manufacturer' for this model, so verify region-specific approvals (for example, CE or UL marks) with Eaton before procurement. Depending on your installation location, you may also need IP rating considerations for enclosure protection. Coordinating with Eaton ensures you meet local electrical standards and installation requirements for safe, compliant deployment.
The product carries a one-year warranty from installation or eighteen months from shipment, whichever occurs first. This provides protection against manufacturing defects and supports a predictable maintenance budget. Pairing the warranty with a solid routine of periodic inspection and coil insulation checks helps reduce unplanned downtime and extends asset life, lowering total cost of ownership over the transformer’s service life.
