FAQs
NT29M23B1516CU is a single-phase 15 kVA transformer designed for 208 V primary and 230 V secondary circuits. Its 818 frame, 20.36 in length, 22.87 in width, and 37.59 in height, along with a 409 lb weight, make it suitable for standard automation panels and compact switchgear spaces. The electrostatic shielding and WS11 weather shield aid EMI protection and outdoor installation, while UL Listed and NEMA TP-1 compliance ensure regulatory compatibility.
Key specs include 60 Hz operation, 15 kVA power rating, primary 208 V, secondary 230 V, copper windings, and voltage taps of +2.5% and -2.5%. The unit supports an 80 °C temperature rise and uses a single-phase configuration. These characteristics provide stable voltage regulation for sensitive control electronics while maintaining efficient heat management in densely packed panels.
Yes. The 15 kVA single-phase design, together with voltage taps and ventilation features, makes it well-suited for high-density control panels and automation enclosures. The electrostatic shielding reduces EMI, and the WS11 weather shield supports outdoor or harsh indoor environments. Its robust copper windings and 80 °C rise rating help sustain reliability under continuous load and frequent switching.
The NT29M23B1516CU is UL Listed and NEMA TP-1 compliant, with DOE 2016 Efficient designation noted in catalog materials. These certifications support regulatory compliance for industrial power management and distribution applications and align with energy-efficiency programs used in modern facilities.
Eaton provides a one-year warranty from installation or eighteen months from shipment (whichever comes first). This, combined with DOE 2016 efficiency and high-quality copper windings, contributes to predictable maintenance costs and favorable total cost of ownership. For ROI, expect improved panel reliability, reduced energy waste, and smoother operation in year-over-year production or process cycles.
