Selling Policy 25-000 - Distribution and Control Products and Services
Feature → Business Impact → Application: K-Factor nonlinear ventilation reduces hotspot formation and improves thermal performance, delivering more stable voltage under nonlinear loads and enabling higher system uptime in data centers and machine rooms. This translates to lower cooling costs and prolonged equipment life, supported by 115 °C rise ratings and copper windings that resist thermal aging. Feature → Business Impact → Application: 112.5 kVA three-phase rating with 460 V primary and 208 Y/120 V secondary offers strong short-term overload tolerance for manufacturing lines, enabling quick ramping without compromising protection. Feature → Business Impact → Application: Tap changes of +2.5% and -2.5% allow precise voltage regulation across fluctuating supply conditions, reducing downstream equipment stress and improving control system stability in packaging and processing plants. Feature → Business Impact → Application: Electrostatical shielding and WS19 weather shield provide EMI containment and environmental protection, enabling outdoor or semi-enclosed installations with predictable performance. Feature → Business Impact → Application: UL Listed and NEMA TP-1 compliant certification ensures regulatory alignment for electrical installations, supporting procurement criteria and reducing project risk across industrial facilities. Feature → Business Impact → Application: Copper windings deliver high efficiency and durability, contributing to lower I2R losses and longer service life in large switchgear assemblies, especially when space is at a premium and enclosure cooling is limited.

FAQs
The N52M28F12CUEE is a three-phase transformer with a 460 V primary and 208Y/120 V secondary and uses a 916A frame. Its copper windings and WS19 weather shield support versatile installation in standard electrical rooms or outdoor enclosures, while the 112.5 kVA rating provides ample headroom for typical data center or manufacturing loads. Ensure panel boards and disconnects are rated for 460 V service and that enclosure space accommodates dimensions 23.42 in D x 28.22 in W x 48.56 in H.
Key specs include a 112.5 kVA three-phase rating, 460 V primary, 208Y/120 V secondary, 60 Hz frequency, copper windings, frame 916A, and taps at +2.5% FCAN and -2.5% FCBN. It offers a 115 °C rise and is UL Listed with NEMA TP-1 efficiency. These figures support reliable operation under load variations and appropriate protection for downstream equipment.
Best suited for data centers, manufacturing floors, and packaged equipment lines, where stable voltage and efficient power distribution are critical. The K-Factor design helps manage nonlinear loads, while the dual secondary 208Y/120 V supports multiple control circuits and PLCs without auxiliary transformers. Its rugged build and weather shield also make it viable for semi-outdoor installations in industrial facilities.
This transformer is UL Listed and meets NEMA TP-1 efficiency standards, with 60 Hz operation. The product notes also highlight electrostatic shielding and WS19 weather protection, which support compliance for various electrical installation codes and standards in industrial environments.
Warranty is Eaton Selling Policy 25-000, offering one year from the date of installation or eighteen months from the date of shipment, whichever occurs first.
