FAQs
The N48M28F49LS47 uses a 918A frame with aluminum windings and a three-phase 480 V primary, making it compatible with standard Eaton distribution assemblies and many retrofit panel layouts. Ensure mounting aligns with the 30.68 in length, 62.18 in height, and 31.44 in width enclosure footprint and verify taps for +/- 2.5% voltage adjustment to match site voltage tolerance.
Key specs include a 150 kVA rating, 60 Hz frequency, 480 V primary, 208Y/120 V secondary, and temperature rise of 115 °C. It features two +2.5% FCAN and four -2.5% FCBN taps, with aluminum windings and an electrostatic shield to minimize interference with adjacent equipment.
Yes. Its three-phase 150 kVA rating, voltage flexibility via taps, low 47 dB sound level, and EMI shielding make it well-suited for data centers and manufacturing environments where stable voltage, quiet operation, and noise-sensitive spaces are priorities.
The unit is UL Listed, providing essential electrical safety certification for industrial applications. This aids in passing regulatory reviews and enhances procurement confidence for audits and safety programs.
The rugged design with aluminum windings and shield reduces thermal stress and EMI-related issues, lowering maintenance needs. The 150 kVA capacity supports scalable loads, while the 60 Hz operation and ventilation help sustain efficiency, contributing to lower downtime and improved system uptime over the life of the installation.
