FAQs
Install the NT20P11S1516 on a stable panel base that supports its 31.3 inch height, 22.89 inch width, and 18.39 inch depth. Ensure mounting clearance for ventilation and the WS11 weather shield option if outdoor or harsh-environment placement is needed. Plan for a total weight of 247 lb and align with frame 816 compatibility for seamless integration with standard enclosure layouts.
Voltage regulation is managed via selectable taps: 1 at +5%, 2 at -5%, 2 at +2.5%, and 4 at -2.5%, enabling compensation for line variance. The unit uses a 240/480 V primary and a 120/240 V secondary at 60 Hz, delivering stable, clean power suitable for sensitive automation equipment and motor controls.
Yes. The transformer is UL Listed and NEMA TP-1 compliant, signaling alignment with recognized electrical safety and performance standards. It is also noted as DOE 2016 Efficient, indicating energy-efficiency compliance and potential operating cost reductions in panel installations.
The 15 kVA, single-phase design with nonlinear ventilation reduces heat buildup and voltage distortion in control panels, improving reliability and uptime. Aluminum windings offer good thermal performance, while the 150°C rise rating supports high-load scenarios. Coupled with DOE efficiency, this delivers lower energy waste and a smaller cooling footprint in modern automation cabinets.
Eaton provides a one-year warranty from installation or eighteen months from shipment, whichever occurs first, under Selling Policy 25-000. Regular maintenance checks should focus on enclosure integrity and cooling airflow, with UL/NEMA TP-1 compliance ensuring ongoing regulatory alignment during lifecycle upgrades or panel refurbishments.
