FAQs
NT20P11F50CUEE is a single-phase transformer rated for 50 kVA with a 240/480 V primary and 120/240 V secondary. In a 3-phase installation, it is typically used as a single-phase leg within a distribution panel or as part of a transformer's bank. Ensure proper neutral grounding, correct phasing, and adherence to local electrical codes. Use appropriate enclosure and wiring routing to support ventilation and access for taps and fusing. Consulting Eaton’s installation guides is recommended for compliant wiring schemes.
Key specs include a 50 kVA rating, primary 240/480 V, secondary 120/240 V, and taps including +5% with -5% and ±2.5% steps. It employs copper windings and a 115°C rise, with a K-Factor nonlinear design to mitigate harmonic content. The unit uses a ventilated cooling approach suitable for indoor installations and standard control-panel environments, aligning with typical low- to medium-voltage distribution needs.
Yes, the K-Factor nonlinear design helps manage harmonic currents, reducing voltage distortion that can affect drives and PLCs. When pairing with motor drives or sensitive electronics, ensure proper harmonic mitigation practices, such as keeping drives within recommended distance from transformers, using proper filtering, and validating voltage regulation under expected load profiles to minimize interference.
Certification needs vary by region. Typical considerations include CE marking for Europe and UL recognition for North America; however, exact approvals for NT20P11F50CUEE should be confirmed with Eaton or the distributor. The product data indicates 'Certifications: Contact Manufacturer,' so verify the unit’s current compliance certificates and any regional electrical standards before installation.
The NT20P11F50CUEE provides improved voltage quality and reduced overheating risk thanks to its K-Factor design and ventilated copper-winding construction. This can translate to longer equipment life, lower maintenance costs, and fewer unplanned outages. Regular inspection of tap connections, cooling pathways, and enclosure integrity supports dependable operation and predictable lifecycle costs.
