Feature → Business Impact → Application: Harmonic mitigation reduces distortion in 480 V three-phase systems, lowering overheating risk and extending downstream equipment life; ideal for data centers and manufacturing lines where harmonic currents threaten reliability. Feature → Copper windings and electrostatic shielding enhance durability and insulation performance; translates to longer service intervals and reduced fault-related downtime in industrial rooms using dry-type distribution transformers. Feature → 150 kVA rating with 60 Hz operation and 15° phase shift provides robust power conditioning for mid-scale electrical rooms; enables stable voltage to sensitive loads such as PLCs, drives, and SCADA systems in both new builds and retrofits. Feature → Taps at +2.5% and -2.5% allow precise voltage regulation; keeps critical loads within tolerance during supply swings, reducing equipment stress and nuisance trips. Feature → Weathershield WS34 and copper coil construction support reliable outdoor and harsh indoor environments, while UL Listed and NEMA TP-1 compliant status minimizes compliance risk for regulated facilities. Feature → Heavy-duty frame 918A with a 1800 lb weight and 30.68 in depth, 62.18 in height, 31.44 in width footprint; simplifies site planning, rack integration, and ventilation in constrained electrical rooms. Feature → 18-month shipment and one-year installation warranty under Eaton policy provides reassurance for ongoing maintenance budgeting and service planning, reinforcing total cost of ownership improvements for distribution networks.

FAQs
Install in a compliant electrical room with adequate clearances for a 1800 lb unit. Verify 480 V three-phase supply, 208Y/120 V secondary connections, and the 200X wiring interface. Ensure ambient conditions meet the 115°C rise rating and provide ventilation; use the WS34 weather shield if outdoor or harsh indoor environments are anticipated.
It is designed to reduce harmonic currents by phase-shifting and filtering distorted waveforms, lowering peak current, reducing overheating, and protecting sensitive equipment. Expect improved voltage stability for drives, PLCs, and other electronics, which translates to fewer trips and longer equipment life in data centers and manufacturing lines.
Yes. With a 150 kVA rating, copper windings, and a dry-type construction, it offers reliable three-phase conditioning for critical loads powered from 480 V, stepping down to 208Y/120 V. The phase shift and voltage taps help maintain consistent voltages across sensitive IT and automation equipment, supporting uptime and mission-critical applications.
The unit is UL Listed and NEMA TP-1 compliant, with a 115°C rise specification. This combination ensures regulatory compliance, safer operation, and efficient performance in line with industry expectations for modern distribution transformers.
Reduced harmonic distortion lowers overheating risks and consumable wear, translating to lower maintenance costs and longer asset life. The unit’s robust warranty (one year from installation or 18 months from shipment) and its durable copper windings support predictable Total Cost of Ownership in power distribution for mid-size facilities.
