General specifications give you a reliable backbone for plant power: a 15 kVA, three-phase transformer with a 200 V primary and 480 V secondary ensures consistent distribution to critical loads. The business impact is clear—stable voltages reduce equipment wear, minimize nuisance trips, and improve line productivity in automated lines. This is ideal for control panels and small substations where space is at a premium and serviceability matters. The enclosure is NEMA 3R rated for indoor-outdoor use, delivering weather resilience and safer outdoor installation without sacrificing accessibility for maintenance. The result is lower maintenance costs and faster commissioning in outdoor zones such as canopy-mounted or yard-side equipment. Tap adjustments (+2.5% FCAN, -2.5% FCBN) provide practical voltage regulation to compensate for line drops and long cable runs, keeping servo drives and relays within specification. This feature boosts system uptime and reduces rework from voltage sag. Aluminum coil design lowers material costs while offering corrosion resistance and good heat dissipation, contributing to a favorable total cost of ownership over the life of the equipment. The UL Listed certification and a 115 °C rise rating deliver safety and reliability in harsh environments, supporting compliance with plant safety programs and industry standards. Weathershield designation of Indoor-Outdoor expands installation options without compromising protection, making field deployment simpler for a variety of applications. Weight and footprint are considered in the 255 lb package, which, when paired with compatible mounting provisions, supports straightforward installation in existing enclosures or new panels. The 200/480 V configuration aligns with common plant power architectures, enabling quick integration with minimal field modification. Finally, the Eaton warranty and service policy provide assurance against unexpected downtime and reinforce long-term performance in mission-critical systems.

FAQs
Installers should plan for a sturdy mounting surface that can support the 255 lb weight and allow adequate clearance for cooling, taps, and terminal access. The NEMA 3R enclosure enables indoor-outdoor placement, but ensure weather exposure is mitigated from direct water spray. Use standard termination practices with the 231C wiring connection code and follow UL Listed wiring guidelines for a safe, compliant installation. Provide appropriate clearances for service and heat dissipation, and verify that the mounting location supports vibration and shock specs typical of industrial environments.
The transformer provides 15 kVA in a three-phase configuration with a primary of 200 V and a secondary of 480 V, operating at 60 Hz. For voltage regulation, it includes two taps at +2.5% FCAN and two taps at -2.5% FCBN. Choose primary voltage to match your supply and use the 480 V secondary to feed 480 V equipment or downstream transformers. The dual taps help compensate for line drops and long runs, improving performance of sensitive loads such as drives and PLC I/O banks.
Yes. The Y72D48T15 is designed with a NEMA 3R enclosure and weather-resistant construction for indoor-outdoor use. It supports rugged outdoor environments typically found in manufacturing floors, outdoor equipment pads, or switchgear rooms that require protection from rain, dust, and corrosion. This capability reduces the need for separate outdoor cabinets and simplifies site integration while maintaining safety and reliability.
The transformer is UL Listed, confirming compliance with safety standards for electrical equipment. The NEMA 3R enclosure provides enclosure protection suitable for indoor-outdoor installations. The 115 °C rise rating indicates robust thermal performance during peak loads, which supports regulatory and safety requirements in industrial environments and helps prevent overheating during continuous operation.
With a 15 kVA rating, aluminum windings, and a rugged enclosure, the Y72D48T15 delivers reliable power with minimal downtime, reducing rework costs and maintenance frequency. The dual taps enable voltage regulation without additional equipment, lowering energy waste and improving equipment life. Eaton’s warranty and service support further mitigate long-term risk, making this transformer a cost-effective choice for expanding or modernizing control panels and distribution systems.
