FAQs
This Eaton harmonic transformer is designed for three-phase 480 V systems feeding sensitive 208Y/120 V loads. With a 150 kVA rating and copper windings, it conditionally mitigates harmonics while providing a stable secondary. Its Weathershield option enables outdoor use, and the unit integrates with standard Eaton power-management workflows for streamlined commissioning, protection, and monitoring across critical feeders.
The X48M28T49CUEENONS2P is UL Listed and NEMA TP-1 compliant, ensuring compliance with safety and efficiency regulations for industrial power distribution. The product notes also reference an 80kA per phase SPD on the secondary with indicator light, reinforcing protection standards for critical circuits.
Key specs include 480 V primary, 208Y/120 V secondary, 60 Hz, three-phase operation, and a 150 kVA rating. The taps are 2 at +2.5% and 4 at -2.5%, allowing voltage adjustment to compensate for load and distribution variations, with a 0° phase shift suitable for balanced systems.
By providing a clean, balanced output and reducing harmonic distortion, the transformer minimizes overheating and equipment stress. The copper windings improve conductivity, while NEMA TP-1 efficiency and UL Listed certification ensure regulatory compliance. Built-in surge protection (SPD) further lowers downtime risk, supporting steadier process performance and energy costs over time.
The transformer carries a one-year warranty from installation or eighteen months from shipment, whichever occurs first. Eaton support offers access to spare parts, technical guidance, and field services if needed. The robust construction with copper windings and dry-type insulation also reduces maintenance frequency, helping lower lifecycle costs for asset-heavy facilities.
