Selling Policy 25-000 - Distribution and Control Products and Services
Feature → Business Impact → Application: Totally enclosed non-ventilated (TENV) design reduces dust ingress and simplifies cooling management, improving reliability in harsh environments and reducing maintenance cycles. This translates to lower total cost of ownership in manufacturing floors and outdoor switchgear where ventilation is impractical. Application: ideal for compact industrial control panels and distribution enclosures where space is at a premium. Feature → Business Impact → Application: Aluminum coil windings provide corrosion resistance and cost efficiency while maintaining strong thermal performance, supporting longer operational life and lower winding replacement costs. Application: suitable for harsh plant environments and outdoor-controlled zones with standard indoor ratings. Feature → Business Impact → Application: Primary 480 V and secondary 208Y/120 V outputs streamline integration with common electrical distribution schemes, reducing wiring complexity and enabling faster installation in new builds or retrofits. Application: data centers, machine centers, and process lines with mixed-voltage loads. Feature → Business Impact → Application: 45 kVA rating with 60 Hz operation supports scalable load handling while preserving voltage stability, enabling tighter control of motors and controls with fewer transformers. Application: feeder transformers for factories and distribution rooms. Feature → Business Impact → Application: Tap changes (+2.5% FCAN and -2.5% FCBN) provide voltage regulation to match system tolerances, reducing voltage drop and improving equipment performance. Application: retrofits in panels needing precise voltage alignment. Feature → Business Impact → Application: Frame 916AN and DT-3 design offer compatibility with standard enclosures and mounting footprints, simplifying installation and future maintenance. Application: retrofit projects and new builds in industrial facilities seeking standardized components. Feature → Business Impact → Application: 80 °C rise rating supports reliable performance under peak loads, ensuring transformer life while meeting short-term demand spikes common in manufacturing lines. Application: processes with variable load profiles and power fluctuations. Certifications and warranty: UL Listed certification ensures safety and regulatory alignment, backed by Eaton’s warranty policy for peace of mind in long-term industrial deployments.

FAQs
The V48M28B45NV uses the DT-3 design with a 916AN frame, aligning with Eaton's standard dry-type distribution footprint. Ensure mounting aligns with the frame dimensions (approximately 23.42 in length, 46.58 in height, 28.22 in width) and provide adequate clearance for cooling and service access. Pre-check enclosure compatibility and verify panel space prior to retrofit.
Key specs include a 45 kVA rating, 60 Hz frequency, three-phase configuration, 480 V primary, and 208Y/120 V secondary. Tap changes are available at 2 at +2.5% FCAN and 4 at -2.5% FCBN to fine-tune output. Aluminum windings and an 80 °C rise support reliable operation in typical industrial environments.
Yes. The totally enclosed non-ventilated design and UL Listed certification make it well-suited for control panels and distribution enclosures. Its compact DT-3 frame and 916AN housing simplify mounting, while the voltage-tap options support precise integration with panel voltages and downstream equipment.
The transformer carries UL Listed certification, providing credible safety validation for industrial installations and compliance with recognized electrical standards. This helps with procurement audits, customer inspections, and reduced risk during commissioning, especially in regulated manufacturing environments.
Being a dry-type, totally enclosed unit minimizes moisture-related issues and simplifies cooling, reducing routine maintenance. Aluminum windings resist corrosion, and the robust enclosure supports long service life in harsh environments, delivering lower lifecycle costs and predictable performance for plant uptime.
