Feature → Business Impact → Application: The N48M47F7516CUS6 uses copper windings and a K-Factor 13 design to handle harmonic-rich loads with lower overheating risk, translating to improved reliability and longer service intervals for motor drives and power electronics in manufacturing lines. This directly reduces unplanned downtime and maintenance costs in critical production zones. Feature → Business Impact → Application: A 75 kVA three-phase transformer with a 480 V primary and 480Y/277 V secondary delivers precise voltage conditioning for feeder panels, enabling tighter regulation and better performance of downstream drives, PLCs, and lighting systems in process plants. Feature → Business Impact → Application: The unit’s NEMA 2 enclosure and 316 stainless steel shield/ enclosure modification provide corrosion resistance and EMI shielding, supporting installation in humid or dusty environments such as food and beverage processing or chemical plants. Feature → Business Impact → Application: Tap settings (+2.5% and -2.5% with 2 and 4 taps) give flexible voltage compensation to accommodate transient loads, improving voltage stability for sensitive electronics and reducing nuisance trips. Feature → Business Impact → Application: DOE 2016 efficiency, UL Listed, and 10 CFR Part 431 compliance deliver energy savings, easier regulatory audits, and lower lifecycle costs, especially for facilities migrating to energy-performance standards in data centers and automated warehouses. Feature → Business Impact → Application: The heavy-duty build (around 1087 lb) with floor or wall mounting and WS60 weathering options simplifies on-site integration in space-constrained rooms, enabling safer installation with standard rigging practices and minimizing rework in retrofits. Feature → Business Impact → Application: The transformer’s 60 Hz operation and 283B wiring reference ensure compatibility with common industrial control systems and panelboards, supporting straightforward retrofits and scalable distribution as facilities grow.

FAQs
Yes. This transformer provides a 480 V primary and a 480Y/277 V secondary in a 3-phase configuration, ideal for factory distribution panels. It uses a floor or wall upright mounting arrangement and a NEMA 2 enclosure, with a 1087 lb weight requiring appropriate lifting gear. For best results, plan clear access to connections (Wiring connection 283B) and refer to the detailed mounting dimensions in the spec sheet.
The unit is rated at 75 kVA with 60 Hz operation, 480 V primary, and 480Y/277 V secondary. Copper windings, a 115 °C rise, and a K-Factor 13 designation support efficient operation under harmonic loading. Compliance includes DOE 2016 Efficient and UL Listed, with a NEMA ST-20 sound level reference for indoor installations.
It features an electrostatic shield option and a 316 stainless steel enclosure modification, providing EMI suppression and corrosion resistance in harsh environments. The WS60 weathershield option further protects the unit in semi-exposed spaces, making it suitable for plant floors, washdown prone areas, and chemical processing facilities.
Plan for torque and wiring clearances around the 283B connection, ensure floor or wall mounting with upright orientation, and account for a heavy lift. Use the included tap options (+2.5% with 2 taps, -2.5% with 4 taps) to counter voltage fluctuations in nearby loads, reducing risk of nuisance tripping and improving voltage stability in evolving automation workloads.
