Feature → Business Impact → Application. The K-Factor nonlinear ventilated design reduces harmonic currents and heat buildup, improving system reliability and prolonging equipment life, which translates to lower maintenance costs in high-load environments like motor drives and presses. This enables engineers to deploy the same transformer across varied facility loads without sacrificing performance, supporting harmonics-sensitive applications and industrial automation lines. The 112.5 kVA three-phase capability with a 480 V primary and 380Y/220 V secondary delivers consistent power for critical loads such as CNC machines, pumps, and packaging lines, reducing voltage dips and improving process stability. Copper windings offer low resistance and high efficiency, resulting in reduced energy losses and cooler operation under heavy-duty duty cycles, especially in tight electrical rooms. The included taps, +2.5% and -2.5%, simplify on-site voltage accommodation, reducing the need for additional equipment and enabling fast commissioning. With UL Listed and NEMA TP-1 efficiency notes, compliance and performance are guaranteed, supporting procurement criteria and insurance requirements. The rugged 916A frame and sizeable footprint ensure robust mounting in industrial panels, while the WS19 weathershield and electrostatic shielding improve outdoor resilience and EMI suppression in harsh environments. These features collectively support faster installation, easier maintenance, and long-term total cost of ownership reduction in facilities with variable loads and stringent safety standards.

FAQs
Installation should follow the device’s three-phase layout, using the 916A frame for mounting in standard control panels. Provide appropriate clearance for cooling and access to the copper windings. Connect primary 480 V to the designated input lugs and secondary 380Y/220 V to the distribution circuits, using the +2.5% and -2.5% taps as needed for voltage matching. Verify UL compliance and secure the from-wall mounting hardware per Eaton guidelines to ensure serviceability and warranty validity.
The transformer uses a 480 V primary and a 380Y/220 V secondary. It features taps at two with +2.5% and four with -2.5% to accommodate small site voltage variations. This flexibility supports stable secondary voltage under fluctuating grid conditions and reduces the need for additional voltage regulation equipment in many installations.
Yes. The N48M37F12CUEE employs a K-Factor nonlinear ventilated design optimized for harmonic-rich environments. Its 115 °C rise rating, copper windings, and robust insulation support continuous operation with reduced overheating and improved efficiency. This makes it well-suited for motor drives, variable-frequency drives, and other automation equipment where harmonic currents are a concern.
The unit is UL Listed and NEMA TP-1 compliant, indicating adherence to recognized safety and performance standards for power transformers. Catalog notes also mark it as NEMA TP-1 efficient, aligning with energy efficiency programs. These certifications facilitate procurement approvals, insurance compliance, and safe integration into industrial power systems.
Maintenance needs are minimized by copper windings, a robust 115 °C rise design, and a durable 916A frame. The unit’s electrostatic shielding and WS19 weathershield enhance reliability in indoor and outdoor environments. A 1-year warranty from installation (or 18 months from shipment) protects against manufacturing defects, supporting a favorable ROI when combined with energy efficiency and reduced downtime.
