FAQs
The N29R47T1216CU is designed for three-phase 208 V primary to 480Y/277 V secondary service. It weighs 1395 lb and supports floor or wall mounting in a NEMA 2 enclosure. Use the E0269A wiring connection and provide adequate clearance for cooling. Ensure mechanical support and crane/lift planning for installation in constrained spaces. Verify DOE 2016 efficiency and UL Listed compliance during commissioning.
K-Factor 13 indicates enhanced tolerance to nonlinear loads and harmonics, reducing winding insulation stress and heat rise. This translates to more stable voltage regulation under varying motor-start and drive conditions, improving overall system reliability. For plants with high-power drives and capacitor banks, the transformer maintains performance without excessive cooling demands.
Yes. The unit carries UL Listing for safety and DOE 2016 Efficient compliance, helping buyers meet federal energy guidelines and qualify for energy rebates. This combination is particularly valuable for regulated industries and programs that reward energy-conscious modernization, while ensuring durable performance in demanding environments.
Typical applications include mid-to-large manufacturing lines, process control rooms, and plant power distribution where reliable three-phase power is required. The 208 V to 480Y/277 V configuration supports common industrial architectures, while the NEMA 2 enclosure and copper windings deliver robust indoor performance in shop floors, assembly areas, and equipment rooms.
Maintenance is minimized by solid copper windings, robust enclosure, and factory-tested insulation with 220 °C rating. Regular checks focus on mounting integrity, wiring connections, and cooling paths. ROI comes from energy savings via DOE 2016 efficiency, reduced cooling load, and avoided downtime due to reliable harmonic handling and UL-listed safety.
