FAQs
This transformer uses a NEMA 2 enclosure and is designed for floor or wall mounting in upright orientation. Plan for a footprint of 34.5 in wide by 51 in high and 31.5 in depth, and ensure a sturdy, level mounting surface. The 283A wiring connection should be sized to support the 75 kVA rating, with adequate clearance for ventilation.
It meets DOE 2016 Efficient standards and is UL Listed, providing recognized efficiency and safety compliance. Copper windings and a 150 °C rise capability further support reliable operation under demanding loads, while the K-Factor 13 design helps manage harmonic content from non-linear loads.
Yes. The primary voltage is 208 V and the secondary is 208Y/120 V, with a 75 kVA three-phase rating. This makes it ideal for facilities that distribute power at 208 V and require a 120 V leg for control circuits and auxiliaries, maintaining stable voltages under varying loads.
The transformer includes an electrostatic shield and an 80 kA SPD to improve transient protection. It also features a NEMA 2 enclosure and WS60 Weathershield options for additional environmental protection, reducing downtime in dusty or damp environments.
The unit provides tap settings of 2 at +2.5% and 4 at -2.5%, enabling precise voltage regulation to compensate for line drops and voltage fluctuations. This reduces the risk of under- or over-voltage conditions, supporting stable operation of downstream equipment and longer asset life.
