Eaton N48M28F45NV Transformer - 3PH 480-208Y/120 TENV
Part Number: N48M28F45NV
Quick Summary
Eaton N48M28F45NV transformer delivers reliable power isolation for industrial control panels. This three-phase device is designed to perform in space-constrained environments without sacrificing reliability. In dense panel racks and compact cabinets, overheating and moisture ingress can drive downtime and maintenance costs, but a totally enclosed non-ventilated (TENV) design helps protect windings and insulation. Certifications vary by region; confirm with Eaton, but typical expectations include CE marking, IP ratings, and SIL capabilities to meet safety and functional requirements. For procurement, this model supports scalable power delivery and easy integration with existing Eaton or third-party distribution equipment, providing a robust foundation for automated systems, machine tools, and process equipment.

Non-ventilated transformer
Totally enclosed non-ventilated design provides dust and moisture protection for critical windings, reducing insulation wear and maintenance cycles. This translates to longer service life in harsh manufacturing environments and less frequent filter and cooling checks. Use in control panels and compact switchgear to prevent overheating and downtime. The 45 kVA three-phase rating delivers consistent voltage transformation from 480 V to 208Y/120 V, supporting reliable power distribution for motors, sensors, and drives. A robust footprint in a heavy-duty enclosure reduces stray currents and improves safety clearance in crowded control rooms. The 115 C temperature rise specification ensures operation within expected limits in closed cabinets, enhancing uptime in high-ambient applications. Mounting compatibility with common electrical rooms and standard enclosures simplifies installation and spare-part management, reducing total-cost-of-ownership. Engineered for quick field service, the unit’s rugged construction supports routine maintenance without extended downtime.

FAQs
The N48M28F45NV is a three-phase, totally enclosed non-ventilated transformer designed for integration into standard electrical enclosures and control panels. Its TENV design helps seal against dust and moisture, making it suitable for compact cabinets and machine tool arrays. Ensure adequate clearance and mounting provisions per the Eaton catalog and the panel manufacturer’s guidelines to maintain serviceability and access for maintenance.
Key specs include a 45 kVA power rating, three-phase configuration, input voltage of 480 V and output of 208Y/120 V, with a 115 C rise. The enclosure is Totally Enclosed Non-Ventilated (TENV), designed for durability in demanding environments. This combination supports stable voltage transformation for motors, drives, and control circuits while maintaining insulation integrity.
Yes. The N48M28F45NV uses a TENV design intended for confined spaces, reducing risk of overheating in dense panel layouts. Its 45 kVA rating provides adequate headroom for typical panel loads, and its rugged construction minimizes maintenance in restricted installations. When deploying in tight spaces, account for heat dissipation and wiring clearance per the manufacturer guidelines.
Certifications for this Eaton transformer are listed as manufacturer-specific in the data, with 'Contact Manufacturer' indicated. For critical regulatory compliance, verify CE marking, IP ratings, and SIL capabilities directly with Eaton for your region and application. Documentation and confirmation should accompany procurement and installation planning to meet local safety and industrial standards.
Investing in the N48M28F45NV can reduce downtime and maintenance costs due to its rugged, dust- and moisture-protected TENV design, and its reliable 45 kVA three-phase output supports stable operation of panels and drives. Although ROI varies by application, advantages include longer service life in harsh environments, fewer maintenance visits, and smoother energy delivery to critical equipment—collectible through reduced unplanned outages.
