FAQs
NT20P11F1516 is a single-phase 15 kVA transformer with 240/480 V primary and 120/240 V secondary, designed for standard control panels and power distribution setups. Its frame 816 footprint, aluminum windings, and WS11 weather shield simplify mounting in both indoor and rugged environments, while taps support voltage fine-tuning during commissioning.
Key specs include 15 kVA rating, single-phase, 60 Hz frequency, primary 240/480 V, secondary 120/240 V, 115 °C rise, and tap settings of +5% FCAN, -5% FCBN, +2.5% FCAN, and -2.5% FCBN. The coil material is aluminum, and it includes an electrostatic shield and WS11 weathershield for durability.
Yes. The NT20P11F1516 is UL Listed and NEMA TP-1 compliant, with notes indicating NEMA TP-1 efficiency. These certifications support compliance, reliability, and energy efficiency in regulated industrial environments.
The K-Factor design targets non-linear harmonic currents, reducing voltage distortion and heat buildup. This improves power quality, extends transformer life, and lessens EMI concerns, which is critical for drives, power supplies, and automation panels operating under harmonic stress.
Plan for a 246 lb unit with frame 816 in a ventilated enclosure, using WS11 weather protection where applicable. Use the taps to fine-tune voltage during commissioning and anticipate a 1-year warranty with Eaton’s support. Regular inspection of windings and shield integrity will help sustain performance in demanding environments.
