Selling Policy 25-000 - Distribution and Control Products and Services
Feature: K-Factor nonlinear ventilation with a three-phase design improves harmonic handling and thermal management. Business Impact: reduces overheating risk, extends equipment life, and lowers maintenance costs in plants with nonlinear loads. Application: ideal for manufacturing lines, motors, drives, and CNC machines where harmonics are prevalent and uptime matters. Feature: Tap changer offering 2 taps at +2.5% and 4 taps at -2.5% enables voltage regulation to accommodate supply fluctuations and load surges. Business Impact: maintains voltage fidelity for sensitive equipment, minimizes production pauses, and improves energy efficiency. Application: data centers, automation panels, and process control rooms operating on 480 V feeders. Feature: Copper windings and a robust frame (Frame 923) enhance conductivity and mechanical durability. Business Impact: higher short-term efficiency and better thermal performance, leading to lower operating temperatures and extended service life. Application: outdoor or indoor installations in harsh industrial environments. Feature: 225 kVA rating with primary 480 V and secondary 480Y/277 V provides versatile distribution for mixed loads and UPS-compatible feeds. Business Impact: reduces the need for multiple transformers, simplifies spare parts inventories, and improves maintenance planning. Application: general power distribution in production lines and critical machines. Feature: Electrostatic shielding and WS37 weather shield protect against EMI and weather exposure. Business Impact: improves reliability in EMI-rich and outdoor sites, lowering failure risk. Application: outdoor subpanels, switchgear rooms, and industrial automation installations. Warranty and compliance: UL Listed, NEMA TP-1 compliant with a one-year warranty from installation or eighteen months from shipment, whichever occurs first.

FAQs
Plan for a secure, level installation of the 2177 lb unit within a sturdy enclosure or mounting frame. Use the 923 frame as a reference and provide clearance for cooling and maintenance access. Ensure 480 V three-phase supply wiring meets torque specs for copper windings and use proper lugs. If outdoor placement is required, specify the WS37 weather shield.
The unit is rated for 225 kVA with a 480 V primary and 480Y/277 V secondary, operating at 60 Hz. It uses copper windings and offers taps at +2.5% and -2.5% for voltage regulation. The temperature rise is 150 °C with a 200 °C insulation system, supporting robust operation in demanding environments.
Yes, outdoor suitability is supported when the WS37 weather shield option is specified. The electrostatic shielding plus weather protection enhance reliability in exposed installations, provided proper clearances and mounting are maintained per Eaton guidelines.
The N48M47T22CUEE is UL Listed and NEMA TP-1 compliant, with NEMA TP-1 efficiency noted on catalog notes. These certifications confirm compliance with safety and performance standards, reducing procurement risk and aligning with regulatory and energy-efficiency requirements for industrial power distribution.
The transformer’s copper windings and robust frame contribute to high reliability and lower maintenance needs. A 1-year warranty from installation (or 18 months from shipment) reduces risk during initial deployment. Its integrated taps and harmonic tolerance help maintain process uptime, minimizing unplanned downtime and spare-part costs in automation-heavy facilities.
