FAQs
For 480 V systems, plan direct mounting in a compliant enclosure and ensure sufficient clearance for cooling. Use the 513H wiring connection to simplify field wiring and verify the NEMA 3R enclosure accommodates indoor-outdoor exposure. Confirm UL Listed status for regulatory compliance and allocate space for heat dissipation given the 115 °C rise rating. Include circuit protection and isolation in your control panel design to maintain safety margins during startup and peak loads.
The S48N14S05 provides a 480 V primary and a 110/220 V secondary with a 5 kVA VA rating. This configuration supports multiple 110 V and 220 V loads from a single transformer, enabling streamlined power distribution for control circuits, automation modules, and small motors. The single-phase, 60 Hz specification ensures compatibility with standard North American industrial power distributions and simplifies panel design.
Yes. Its 5 kVA capacity, 480 V to 110/220 V outputs, and NEMA 3R enclosure are well-suited for control panels and machine tool applications. The aluminum coil reduces weight for easier installation, while UL Listed approval provides regulatory confidence. The compact footprint and convenient wiring via 513H connectors help minimize panel depth, making it a practical choice for retrofit upgrades and new machinery.
Key compliance factors include UL Listed certification and the NEMA 3R enclosure rating, which supports indoor-outdoor use and rugged environmental conditions. The 60 Hz, single-phase design aligns with common industrial power standards, while the enclosure protection and weather resistance help meet safety and reliability requirements for harsh or variable environments.
Regular visual inspections of the enclosure and connections, plus periodic thermal checks to ensure the 115 °C rise is within acceptable limits, help sustain reliability. The aluminum winding provides good resistance to corrosion and lighter weight during servicing. The 1-year warranty under Eaton policy adds coverage for early-life issues, supporting predictable maintenance budgeting and faster ROI through reduced downtime.
