FAQs
The N29M28T45CUEES3 is designed for three-phase systems with a 208 V primary and 208Y/120 V secondary. Plan for adequate clearance around the vented enclosure, ensure proper mounting to support the 661 lb weight, and verify copper windings are not exposed to overload. Use the ± voltage taps to fine-tune supply to sensitive controls, and confirm compliance with UL Listed and NEMA TP-1 guidelines during commissioning.
The taps (+2.5% and -2.5%) allow on-site voltage adjustment to maintain stable secondary levels when supply or load varies, reducing voltage sag or overvoltage scenarios that stress drives and controllers. The 60 Hz rating matches standard North American power systems, ensuring predictable magnetizing current, impedance, and short-circuit behavior for motors and drives.
Yes. With a 45 kVA rating and 208 V primary to 208Y/120 V secondary, it suits motor control centers, PLC power rails, and automation panels. Copper windings and robust insulation handle moderate continuous loads, while the NEMA TP-1 efficient design helps meet energy-performance goals and reduces operational costs in high-demand production environments.
The transformer is UL Listed and NEMA TP-1 compliant, signifying built-in safety and efficiency per recognized standards. This helps with regulatory audits, insurance requirements, and procurement spec alignment, especially in facilities pursuing reliability incentives and energy-management programs.
Routine inspections should verify insulation integrity, verify tap connections, and ensure the WS39 weather-shield is intact for outdoor or harsh environments. Copper windings offer high reliability with excellent thermal characteristics. While initial cost is higher than basic transformers, the combination of high efficiency, reduced downtime, and long-term energy savings supports a favorable ROI for plants with demanding duty cycles.
