FAQs
The N29M29F7516 is designed for 208 V primary and 208 V secondary in a three-phase delta configuration operating at 60 Hz, with a 75 kVA rating. Its windings use aluminum for efficiency and lighter installation, and its NEMA 2 enclosure protects against dust in indoor environments. This combination ensures reliable voltage transfer and straightforward integration into standard industrial panels.
DOE 2016 efficiency reduces no-load and load losses, lowering heat generation and cooling needs. For a 75 kVA, 60 Hz transformer like the N29M29F7516, this translates to measurable energy savings over the life of the equipment, offsetting capital cost through lower utility bills and improved thermal performance in continuous operation.
Plan for floor or wall mounting in upright orientation, as specified, with a frame size of 943 and dimensions roughly 31.5 in (length) by 34.5 in (width) by 51 in (height). Expect a weight near 988 lb. The NEMA 2 enclosure and WS60 weathering option provide enclosure protection suitable for dry indoor spaces and moderate humidity environments.
The N29M29F7516 provides two tap positions: +2.5% and -2.5%. This enables fine-tuning of output voltage under varying load and input conditions, helping to maintain consistent voltage at critical equipment and reducing stress on downstream components, motors, and drives.
This transformer is UL Listed and meets DOE 2016 Efficient requirements as per 10 CFR Part 431. The combination of these certifications ensures safety, energy efficiency, and regulatory compliance in industrial installations, while the 115°C rise insulation and 220°C rated insulation provide robust thermal performance for continuous operation.
