FAQs
The N29M28F75EE is designed for three-phase service with a 208 V primary. Install according to its 916A frame footprint, mount in a suitable electrical room, and connect primary windings to the 208 V supply. Wire the 208Y/120 V secondary to the load distribution panel, observe polarity, and use the +/- 2.5% taps to fine-tune voltage. Follow UL-listed installation practices and ensure proper ventilation for the 115 °C rise rating. If outdoor installation is required, apply WS19 weather shielding and position the transformer to minimize exposure potential.
Key specs include 75 kVA, 60 Hz, three-phase operation, primary voltage of 208 V, and secondary of 208 Y/120 V. The device provides taps at +2.5% and -2.5% to compensate for supply voltage variations, helping to maintain stable voltages to critical loads and reduce nuisance trips. The transformer features aluminum coil material and a 916A frame, with an 115 °C rise rating to ensure reliable operation under load.
Yes, the N29M28F75EE supports outdoor or damp environments when paired with the WS19 weathershield and proper enclosure. Its electrostatic shielding adds safety and EMI protection, while the 115 °C rise rating accommodates warmer installation environments. Always verify site exposure and apply the weather shield to maintain longevity in outdoor electrical rooms or exterior transformer pads.
The transformer is UL Listed and NEMA TP-1 compliant, with an NEMA TP-1 efficient catalog designation. These certifications affirm safety, performance, and efficiency, helping facilities meet code requirements and simplify procurement and inspection processes. The product also aligns with standard installation practices for industrial power distribution.
With a 75 kVA rating, robust cooling (115 °C rise), and UL/NEMA TP-1 compliance, the N29M28F75EE offers dependable service life and reduced downtime. The electrostatic shielding and WS19 protection reduce maintenance and enclosure costs, while the taps help maintain voltage stability, lowering energy waste and improving overall system efficiency. The one-year warranty further mitigates initial ownership risk.
