Tap size and voltage regulation are built in with 2 taps at +2.5% and 4 taps at -2.5%, enabling precise voltage control under fluctuating loads. Business impact: tighter voltage regulation reduces nuisance trips and equipment stress, improving uptime for motors and drives in industrial lines. Application: facility power distribution and PV-inverter interfaces benefit from stable 480 V mains and accurate downstream voltage. Copper windings offer low resistance, enhanced thermal performance, and long-term reliability. Impact: lower I²R losses and improved heat dissipation translate to extended transformer life and reduced cooling requirements. Application: data centers, factory floors, and outdoor enclosures in harsh environments. Electrostatically shielded construction minimizes EMI, protecting sensitive controls and metering while meeting EMI/EMC expectations in modern plants. Impact: cleaner signal integrity and safer cabinet operation. Application: PLCs, HMIs, and instrumentation close to power sources. WS34 weathershield enables outdoor installation without compromise. Impact: outdoor durability reduces enclosure costs and accelerates deployment. Application: outdoor switchgear rooms and unprotected locations. 60 Hz, three-phase operation with a -15° phase shift ensures compatibility with common utility and facility electrical designs. Impact: easier paralleling and improved harmonic management. Application: modern manufacturing lines and data-intensive facilities. NEMA TP-1 efficient and UL Listed certification simplify procurement and compliance, while the modest 112.5 kVA rating supports scalable expansion. Impact: predictable energy costs and reduced total cost of ownership. Application: mid-size industrial plants and mixed-use facilities seeking reliable power quality with straightforward maintenance.

FAQs
Installation requires connecting the 480 V primary to the incoming three-phase supply and wiring the 208Y/120 V secondary to downstream loads. Use the 200X wiring connection and follow the manufacturer’s torque specs, while utilizing the device’s taps (+2.5% and -2.5%) to fine‑tune voltage under load changes. Ensure proper enclosure, grounding, and adherence to UL Listed guidelines. The unit is a dry-type transformer designed for 60 Hz operation and copper windings, with a phase shift of -15° to support harmonic management.
Key specs include a 112.5 kVA rating, 480 V primary, 208Y/120 V secondary, 60 Hz, three-phase design, and -15° phase shift. Copper windings and a 115 °C rise indicate robust thermal performance. Taps at +2.5% and -2.5% allow voltage regulation, while NEMA TP-1 compliance and UL Listing confirm standards conformance for reliability and safety in commercial/industrial environments.
Yes. The 480 V to 208Y/120 V secondary configuration, 60 Hz three-phase operation, and high-quality power conditioning capabilities make it well-suited for data centers, manufacturing lines, and PV integrations. Its harmonic mitigation reduces distortion and improves power quality, which helps protect sensitive IT equipment and inverters, while the copper windings and 115 °C rise support reliable, continuous operation.
This Eaton unit is UL Listed and NEMA TP-1 Compliant, with catalog notes indicating NEMA TP-1 efficiency. These certifications support safe operation, energy efficiency claims, and simplified procurement for regulated environments. The transformer’s 60 Hz, three-phase design and electrostatically shielded construction further enhance compliance with common electrical standards in industrial facilities.
Warranty coverage is Eaton’s policy: one year from installation or 18 months from shipment, whichever occurs first. The copper windings and robust dry-type design reduce cooling and maintenance needs, contributing to longer service life and lower operation costs. With NEMA TP-1 efficiency and reliable harmonic mitigation, facilities typically see improved motor and drive performance, lower energy losses, and more predictable total cost of ownership.
