FAQs
This unit uses a 208 V primary and 208Y/120 V secondary, making it compatible with standard 208 V indoor distribution networks and downstream equipment designed for 208Y/120 V. The 60 Hz frequency fits common North American power systems, and the 2 at +2.5% / 4 at -2.5% tap settings support voltage adjustments to maintain proper load voltage when supply varies.
A 45 kVA three-phase transformer offers ample headroom for mid-sized loads while maintaining compact physical footprints. The result is improved voltage stability for motors and controls, reduced risk of undervoltage conditions, and enhanced efficiency due to the DOE 2016 compliant design, which lowers operating heat and energy costs over time.
Yes. The unit’s copper windings, electrostatic shield option, and precise tapping enable compatibility with a wide range of distribution equipment and existing gear in control panels and switchgear. The NEMA 2 enclosure provides rugged indoor protection, helping simplify retrofits where environmental exposure and ease of installation are considerations.
The N29M28T4516CU carries UL Listed certification and is designed for DOE 2016 Efficient performance under 10 CFR Part 431. These certifications ensure safety, reliability, and energy efficiency in commercial and industrial environments, supporting procurement requirements and regulatory compliance.
Expected ROI comes from energy savings due to DOE 2016 efficiency, reduced cooling load from lower heat dissipation, and longer equipment life due to stable voltage delivery and EMI control with the electrostatic shield option. Easy installation and compatibility with common voltage standards also minimize downtime during replacements or upgrades.
