FAQs
NT48M12S15CUEE is a 1-phase 15 kVA transformer with a 480 V primary and 120 V secondary, designed for installation in standard industrial control panels and switchgear. It supports copper windings and a ventilated cooling approach for reliable operation. When planning installation, verify enclosure access, cooling clearance, and adherence to local electrical codes and panel builder guidelines.
A K-Factor nonlinear transformer is designed to accommodate nonlinear load profiles without excessive heating and voltage distortion. It improves voltage regulation, reduces harmonic losses, and extends service life by distributing losses more evenly. This makes it well suited for machine drives, inverters, and other equipment that draw irregular currents, enhancing overall system reliability.
Yes. The NT48M12S15CUEE includes taps that allow ±2.5% voltage adjustment, with two taps at +2.5% and four taps at -2.5%. Use these during commissioning or maintenance to compensate for long cable runs, aging, or supply fluctuations, helping maintain stable downstream voltages and protecting sensitive equipment.
Certification specifics for this Eaton transformer are typically defined by the project requirements and manufacturer documentation. Common considerations include CE marking for European compliance and IP-rated enclosures for environmental protection. For precise approvals, consult Eaton’s datasheet and coordinate with your local authorities and inspectors to obtain the necessary documentation.
The 15 kVA K-Factor transformer uses copper windings and a ventilated design to improve efficiency and thermal performance, reducing energy losses and cooling needs. The result is lower operating costs, longer service intervals, and higher uptime for automated processes. In panel builds, this translates to smaller heat loads, easier cooling planning, and more predictable maintenance cycles.
