FAQs
The N29M28F75A is a three-phase 75 kVA transformer with a frame 915D and aluminum windings. It supports standard field connections suitable for typical electrical rooms and enclosures. For installation, ensure adequate clearances for ventilation and access to taps, and reference the WS39 weather shield if mounting outdoors or in semi-enclosed spaces.
The K-Factor nonlinear design addresses harmonic currents by providing enhanced regulation and reduced harmonic distortion at the point of common coupling. This results in cleaner voltage profiles for critical loads, less stress on downstream equipment, and improved overall efficiency in systems with non-linear loads such as VFDs and switching supplies.
Yes. The transformer combines a rugged ventilated design with an 115°C rise rating, three-phase 60 Hz operation, aluminum windings, and an electrostatic shield, making it suitable for data centers and harsh industrial environments where reliability and EMI control are priorities. WS39 weathershield further enhances outdoor or semi-exposed installations.
The N29M28F75A carries UL Listed certification, signifying compliance with recognized safety standards for electrical equipment. This eases commissioning and procurement, supports safety audits, and aligns with most facility and contractor safety requirements for industrial power distribution equipment.
Plan for periodic thermal checks, especially during peak loads, to monitor winding temperatures and ventilation performance. The unit's 115°C rise rating provides robust short-term capacity, while the WS39 shield and aluminum windings reduce cooling and corrosion concerns. Regular inspection of taps and enclosure integrity helps sustain performance and minimize unplanned downtime.
