FAQs
The H29M28B1516CU is a 3-phase transformer with a 208 V primary and 208Y/120 V secondary rated at 15 kVA, operating at 60 Hz. It supports floor or wall mounting (FR940 frame) and a NEMA 2 enclosure for indoor use. Wiring is configured via 283A, with voltage taps at +2.5% and -2.5% to accommodate supply variations.
This transformer meets DOE 2016 Efficient standards, providing energy-efficient operation. It features copper windings for high conductivity and an 80 °C rise rating, enabling reliable heat dissipation under load. The ventilated design further mitigates hotspot formation, supporting longer service life in continuous operation.
Yes. The unit is designed for indoor panel applications with a NEMA 2 enclosure and UL Listed certification, ensuring compliance and protection in controlled factory spaces. Its 15 kVA three-phase rating and 208V to 208Y/120V outputs suit machine controls and panel boards while maintaining reliable voltage delivery.
The transformer provides taps at +2.5% and -2.5% to compensate for input voltage variations. This enables tighter secondary voltage regulation under load, improving performance for sensitive equipment and reducing nuisance tripping in critical control circuits.
With copper windings, a rugged NEMA 2 enclosure, and DOE 2016 efficiency, maintenance needs are minimized and energy losses are reduced. The robust construction supports long service life in demanding environments. In terms of ROI, energy savings and reduced panel counts translate to a shorter payback period and lower total cost of ownership.
