Eaton Specification Sheet - N48M47F33A
Feature → Business Impact → Application: K-13 nonlinear ventilated design reduces harmonic currents and stabilizes voltage profiles, leading to improved equipment life and reduced overheating in critical loads. This translates to lower maintenance costs and higher uptime for data centers, manufacturing lines, and process facilities. Application: ideal for facilities demanding strict power quality and reliable operation. Feature → Aluminum windings with electrostatic shielding provide robust electrical performance and EMI mitigation, supporting sensitive control systems and PLCs in automation setups. Application: aligns with OEM drive and controller cabinets where EMI suppression matters. Feature → WS35 weather shield and ventilated frame 919 enable resilient operation in challenging environments, including outdoor installations or switchgear rooms with limited cooling. Application: installation flexibility reduces site constraints and speeds commissioning. Feature → 60 Hz, three-phase configuration with 480 V primary and 480Y/277 V secondary supports standard industrial feeders, minimizing cabling changes and improving compatibility with existing panels. Application: streamlined integration in plants and campuses. Feature → +/- tap settings (+2.5% FCAN, -2.5% FCBN) allows precise voltage regulation to maintain customer-specific tolerances, reducing voltage-related equipment stress. Application: enhances reliability for critical motors and reactors. Feature → UL Listed certification and one-year warranty (plus 18 months from shipment) provide regulatory confidence and predictable service coverage, mitigating risk during procurement. Application: procurement and compliance teams gain clear governance for industrial power products.

FAQs
Plan for a sizeable footprint: 36.23 in depth, 44.2 in width, and 75 in height with a 2700 lb weight. The unit requires appropriate mounting, crane access for installation, proper ventilation, and clearance for WS35 weather shield. Ensure connection to standard 480 V/480Y-277 V distribution panels and verify space for service access and future maintenance.
The K-13 nonlinear ventilated design mitigates harmonic currents by shaping the transformer response to non-linear loads. This improves voltage regulation, reduces heating in connected equipment, and helps meet power quality standards. For facilities with high harmonic content from drives or non-linear loads, this helps maintain uptime and protects sensitive equipment.
Yes. With a 300 kVA rating, three-phase 60 Hz operation, and 480 V primary to 480Y/277 V secondary, the N48M47F33A supports essential feeders and UPS interfaces. The aluminum windings, electrostatic shield, and WS35 shield enhance reliability and EMI performance, making it well-suited for data centers, critical manufacturing lines, and hospital equipment feeds.
The transformer is UL Listed, providing recognized electrical safety compliance. No additional certifications such as CE or IP ratings are indicated in the provided data, so confirm regional certification requirements with Eaton prior to global deployment. Warranty coverage includes one year from installation or eighteen months from shipment, whichever comes first.
Plan for routine inspections of cooling pathways, vented enclosure integrity, and electrical clearances around the WS35 shield. With a heavy frame and aluminum windings, ensure crane access for movement and regular thermal checks. The one-year warranty (18 months from shipment) provides initial coverage, while proactive maintenance reduces unplanned downtime in critical power paths.
