FAQs
N29M28T7516 comes with a NEMA 2 indoor enclosure and supports floor or wall mounting, providing flexible installation for crowded mechanical rooms or panel yards. The FR943 frame delivers rigidity, while dimensions of 31.5 in L x 51 in H x 34.5 in W and a 986 lb weight influence handling, rigging, and space planning in typical industrial facilities.
This transformer is rated at 75 kVA with a three-phase 60 Hz operating regime. It features a 208 V primary and a 208Y/120 V secondary, aluminum windings, and a voltage-tap capability of 2 at +2.5% and 4 at -2.5%. These specs support stable power delivery to common 208 V-controlled equipment and automation panels.
K-Factor 13 indicates enhanced nonlinearity management for real-world harmonic conditions, improving EMI/EMC performance and overall efficiency. This design helps minimize overheating in non-linear load scenarios, supporting longer transformer life and more predictable operation in automated systems and facilities with mixed loads.
The N29M28T7516 is UL Listed and DOE 2016 Efficient compliant, with a 10 CFR Part 431 reference and a 150 °C rise insulation profile. These certifications ensure safety, energy compliance, and alignment with regulatory requirements for industrial transformers installed in controlled indoor spaces.
