Eaton N48M28F2216CU-US Transformer - DOE 2016 Efficient

DOE 2016 Efficient designation helps reduce energy consumption across extended operation, particularly in facilities with variable loads and frequent start/stop cycles. The 225 kVA rating provides ample headroom for typical manufacturing lines and automation modules, while maintaining low core and copper losses that translate into measurable energy savings over the transformer’s life. Its three-phase configuration, 480 V primary, and 208Y/120 V secondary support common panel boards and switchgear arrangements used in industrial plants. The K-Factor 13 nonlinear windings mitigate harmonic currents from drives, rectifiers, and uncontrolled loads, improving system stability and reducing the risk of overheating that shortens component life. This design supports longer service intervals and reduces the probability of nuisance tripping during peak harmonic events, which translates into lower maintenance costs and improved production uptime. For facilities adopting power quality standards, this transformer helps maintain voltage integrity without additional filtering. Voltage regulation is enhanced by taps: two at +2.5% FCAN and four at -2.5% FCBN, enabling precise compensation for line drops and load changes. This capability minimizes voltage stress on motors and PLC inputs, extending equipment life and reducing nuisance resets. The built-in tap capability also simplifies commissioning, allowing technicians to dial in the correct voltage at startup without external autotransformers. Copper windings and a 220 °C insulation rating offer robust thermal margins in demanding environments, with a temperature rise specification of 115 °C to support continuous operation under typical facility conditions. The copper construction delivers superior conductivity and reliability compared with aluminum equivalents, while UL listing and the Case E frame provide predictable performance under vibration and routine handling during installation and service. Enclosure is NEMA 1, suited for indoor, dust-protected spaces, with floor mounting that aligns with common mechanical room layouts and skid-based installation workflows. The RH6 weathershield option adds protection against incidental exposure in mildly corrosive or dusty environments, extending service life in plant settings. The 60 Hz rating ensures seamless integration with North American systems and existing switchgear stock. Energy efficiency, UL certification, and DOE compliance simplify procurement and regulatory review, while copper windings and robust construction improve total cost of ownership. The unit’s made-in-America manufacturing base supports local supply chains and long-term serviceability.
