Encapsulated EP construction with copper windings provides rugged protection against dust, moisture, and incidental vibration. This improves reliability and reduces planned maintenance costs in harsh environments. It is ideal for indoor-outdoor installations such as outdoor switchgear, equipment yards, and protected plant rooms. 60 Hz single-phase operation with a 25 kVA VA rating and a 480 V primary to 120/240 V secondary delivers clean, stable power for controls and actuators. The compatibility with common industrial feeders minimizes the need for secondary step-down devices, reducing install time and potential fault points. Tap size 2 at -5% FCBN allows voltage adjustments to accommodate supply variations to improve control reliability without transformer replacement. Copper windings and an 80 °C rise rating indicate strong thermal performance and efficiency, reducing heat-related losses and extending service life. Indoor-Outdoor weathershield and electrostatic shielding provide enclosure protection and EMI mitigation for outdoor installations, data centers, and exposed plant areas, increasing uptime. Weight of 420 lb and dimensions of 14.12 in L, 16.35 in W, and 23.31 in H enable precise space planning in constrained mechanical rooms and equipment pads. Warranty coverage of one year from installation (or 18 months from shipment) further reduces ownership risk, supporting predictable lifecycle budgeting. This combination supports common industry use cases such as machine control panels, motor drives, and distribution feeders, delivering reliable power alongside simplified installation and maintenance routines.

FAQs
This unit is designed with an indoor-outdoor enclosure and electrostatically shielded construction, enabling installation in switchyards, protected outdoor areas, or machine rooms. Plan for a 14.12 in L x 16.35 in W footprint and a 23.31 in tall profile, with a weight of 420 lb. Ensure proper foundations and clearances for service access and heat dissipation.
The transformer operates at 60 Hz single-phase with a primary voltage of 480 V and a secondary of 120/240 V, rated at 25 kVA. This configuration supports typical industrial control panels and 480 V feeder arrangements without additional step-down gear.
Yes. Its 25 kVA rating, copper windings, and encapsulated EP design provide reliable SWaP-optimized power with good thermal performance. The 2 taps at -5% FCBN assist voltage stabilization under feeder variation, aiding sensitive control circuits in manufacturing environments.
Certifications for this Eaton transformer can vary by region; Eaton requires confirmation from the manufacturer for exact scope. Typical considerations include CE marking and IP-rated enclosure depending on installation location and local regulations. Always verify with Eaton or your distributor to ensure site-specific approvals are met.
The product includes a warranty of one year from the date of installation or eighteen months from shipment, whichever comes first. This provides risk mitigation for maintenance planning and supports longer lifecycle cost reduction in capital projects.
