Eaton Specification Sheet - N48M47F49CUEETRLS45
Feature: K-Factor nonlinear, ventilated design improves harmonic response and cooling under load, reducing thermal losses and extending service life. Business impact: Better power quality translates to fewer nuisance trips and longer intervals between maintenance windows. Application: Ideal for 3‑phase distribution in manufacturing, packaging, and process environments where space is limited and loads are variable. This combination also supports modular upgrade paths and simplifies spare parts planning for maintenance teams. Feature: Voltage taps provide 2 at +2.5% and 4 at -2.5%, enabling precise regulation as system voltage varies. Business impact: Tight voltage control minimizes motor voltage stress, extends equipment life, and reduces energy waste. Application: Works well in facilities with mixed loads, sensitive controls, and long feeder runs from 480 V primary to 480Y/277 V secondary in varied plant layouts. The tap scheme is compatible with standard 480 V distribution practices and helps meet harmonic mitigation strategies. Feature: Copper windings offer high conductivity and robust short‑term fault resistance. Business impact: Improved efficiency, lower copper loss, and better thermal performance support reliable operation during peak demand. Application: Suited for high‑demand automation lines, conveyors, and presses that demand steady voltage under load surges. Industry feedback from users highlights reduced thermal hotspots and improved uptime during peak demand periods. Feature: NEMA 2 enclosure with electrostatic shielding and Weather Shield option WS34 protects internal components from dust and moisture. Business impact: Enhanced reliability in indoor plant rooms and moderately harsh environments, reducing corrosion and uptime risk. Application: Ideal for retrofit or new installations in control rooms and transformer rooms with restricted ventilation. Feature: 150 kVA, 60 Hz, primary 480 V and secondary 480Y/277 V, copper windings, and UL Listed compliance deliver ready-to-use power for industrial lines and processes. Business impact: Predictable performance reduces commissioning time and supports regulatory compliance while meeting your facility’s safety and efficiency targets. Application: Suitable for automation, material handling, and packaging lines requiring stable, compliant power distribution.

FAQs
Install the transformer in a clean indoor location with adequate clearance for wiring, ventilation, and service access. Use the NEMA 2 enclosure as specified and connect to the 292A wiring terminals. Verify UL Listed compliance and ensure a balanced 60 Hz 480 V service. Follow Eaton installation guidance, secure mounting, and provide proper overcurrent protection and grounding per local electrical codes.
The unit provides two taps at +2.5% and four taps at -2.5% to fine-tune the primary voltage. Use taps during installation to maintain output voltages within tolerance, especially when feeders are long or supply voltage fluctuates. Change taps with the service de-energized and follow the manufacturer’s guidelines to avoid subjecting equipment to transient voltages.
Yes. With a 150 kVA rating and a 480 V primary to 480Y/277 V secondary, it supports control panels, drives, and lighting common in automation lines. The K-Factor nonlinear design helps mitigate harmonics, while the copper windings and robust enclosure support reliable operation in busy manufacturing environments.
The transformer is UL Listed, indicating compliance with widely recognized safety standards. It uses a NEMA 2 indoor enclosure, is designed for 60 Hz operation, and is aligned with energy efficiency expectations (NEMA TP-1). These certifications support safe installation, regulatory compliance, and streamlined procurement for regulated facilities.
Maintenance is typically routine: inspect connections, verify clearance, and monitor operating temperatures. The unit’s copper windings and efficient design reduce energy losses, contributing to lower operating costs over time. With UL Listing and a robust 150 kVA rating, commissioning is faster, downtime is minimized, and overall lifecycle costs are easier to justify in automation projects.
