FAQs
The Eaton S54N11P16 installs by mounting the encapsulated unit in a compliant enclosure or panel, wiring the primary to 120/208/240/277 V and the secondary to 120/240 V, and securing with the FR68P frame. Ensure UL Listed labeling is visible, and observe 60 Hz operation and proper heat dissipation to maintain 115°C rise limits.
Key electrical specifications include a 1.5 kVA rating, single-phase configuration, 60 Hz frequency, and primary voltages of 120, 208, 240, or 277 V with a 120/240 V secondary. The unit uses an aluminum coil, 130°C insulation, and a 115°C rise, enabling safe operation in standard control-system environments. This combination supports compact installations and predictable performance across typical industrial loads.
Yes, the S54N11P16 is suited for outdoor and harsh environments because it uses a NEMA 3R enclosure and aluminum coil for corrosion resistance and efficient heat management. With UL Listed safety, 60 Hz operation, and a compact 6 by 13.78 by 6 inch footprint, it fits through standard panel openings while maintaining reliable isolation.
The transformer meets multiple compliance benchmarks critical for industrial electrical design. It is UL Listed for electrical safety, features a NEMA 3R enclosure for outdoor and damp environments, and provides 60 Hz operation at a 1.5 kVA rating. This combination supports reliable isolation for control circuits while simplifying maintenance and spare-part planning.
From a maintenance and ROI standpoint, the encapsulated aluminum-coil design reduces routine service and replacement parts, while the rugged FR68P frame and 115°C rise tolerance minimize thermal stress. The 42 lb weight simplifies installation and servicing, and the 1.5 kVA rating covers typical control loads, delivering higher uptime and lower total cost of ownership over the asset lifecycle.
