Selling Policy 25-000 - Distribution and Control Products and Services
The S48M23S25CU delivers 25 kVA at 60 Hz from 480 V to 230 V, enabling mid-size loads in industrial panels with improved efficiency and reduced heat buildup. Copper windings minimize losses and extend transformer life, translating to lower operating costs and longer intervals between maintenance cycles in demanding environments. The NEMA 3R enclosure supports indoor-outdoor installations, eliminating the need for separate protective housings and speeding up site deployment, whether in factories or outdoor equipment enclosures. Tap settings—2 at +2.5% FCAN and 4 at -2.5% FCBN—offer precise voltage regulation to accommodate supply fluctuations, reducing voltage-related equipment wear and safeguarding sensitive controls. Weathershield compatibility further broadens where this transformer can live, streamlining procurement for mixed-site footprints. With UL Listed certification and a rugged 182 frame, it aligns with strict safety standards while fitting common mounting footprints, accelerating commissioning and reducing total installed cost. The combination of a 14.12 in length, 16.35 in width, and 23.31 in height helps engineers optimize panel real estate and maintain adequate clearances for heat dissipation. Finally, the 25 kVA rating supports robust power distribution and control architectures in manufacturing, water treatment, and process automation scenarios, delivering predictable performance with lower lifecycle risk.

FAQs
This transformer measures about 14.12 in long, 16.35 in wide, and 23.31 in high, and weighs 428 lb, guiding mounting and clearance planning. It uses a durable NEMA 3R enclosure for indoor-outdoor use and is UL Listed, reducing enclosure variability. Ensure proper support, ventilation, and safe clearance to maintain optimal cooling and service access.
Key specs are 25 kVA, 480 V primary, 230 V secondary, 60 Hz, single-phase operation, with voltage taps of 2 at +2.5% FCAN and 4 at -2.5% FCBN. These values determine load capacity, voltage regulation, and compatibility with panel design, enabling predictable control performance and safe integration with existing power systems.
Yes. The S48M23S25CU features a NEMA 3R enclosure and indoor-outdoor compatibility, supported by Weathershield options in related products. This combination enables reliable operation in exterior locations or variable climates, reducing the need for additional protective housings and simplifying site planning for outdoor control panels.
It carries UL Listed certification, indicating compliance with safety standards. The Eaton warranty policy 25-000 offers one year from installation or eighteen months from shipment, whichever occurs first, providing protection against manufacturing defects and supporting maintenance planning for total cost of ownership.
Plan for a 25 kVA load with proper heat dissipation given a 115 °C rise rating. Use the 182 frame footprint for mounting convenience, and ensure correct wiring (480 V to 230 V) and tap connections are secure. Position for easy access to taps and terminations, and verify vibration isolation to minimize wear during long-term operation.
