K-Factor nonlinear design with ventilation enhances harmonic resilience and thermal performance, reducing hotspot risk in high-crest factor loads. This improves insulation life and lowers maintenance costs, particularly in facilities with variable loading such as plastics, metal fabrication, and batch processing lines. The 225 kVA rating at 60 Hz supports substantial power transfer, enabling equipment starting and operation without voltage drop concerns, which translates to higher production uptime and fewer process interruptions. Ventilation combined with a 150°C rise rating provides robust thermal margins, allowing sustained operation under peak demand conditions and in environments with limited cooling. Tap options (2 at +2.5% FCAN, 4 at -2.5% FCBN) offer precise voltage regulation to match site bus voltages, reducing capacitor banks and improving overall system efficiency. Aluminum windings and an electrostatically shielded construction enhance durability and reduce stray losses, boosting long-term efficiency and reliability. The WS37 weather shield and frame 923 design support versatile installation, including outdoor or harsh indoor environments, while maintaining compact footprint and serviceability. The UL Listed certification and Eaton warranty reinforce procurement confidence and compliance across project scopes, from data centers to manufacturing floors.

FAQs
Plan for a clear installation footprint of 32.65 in (length) by 57.54 in (height) by 36.69 in (width) with room for access and ventilation. Mount on a rigid base compatible with frame 923, and shield exposed components with the WS37 weather shield if outdoor or harsh environments are expected. Ensure proper clearances for cooling air, wiring, and service access as part of a standard maintenance regimen.
The transformer is rated 225 kVA at 60 Hz, three-phase, with a primary voltage of 480 V and a secondary of 400Y/231 V. It provides taps at 2 at +2.5% FCAN and 4 at -2.5% FCBN, and operates with a 150 °C rise. Aluminum windings and electrostatic shielding enhance performance and durability, while UL Listed certification confirms safety compliance.
Yes, it incorporates the WS37 weather shield for enhanced outdoor resilience and corrosion protection. While UL Listed covers safety compliance, ensure the installation location respects environmental conditions and available ventilation. The frame 923 housing and ventilated design are chosen to maintain performance in exposed or semi-exposed spaces.
Expect robust, low-maintenance operation due to aluminum windings, electrostatic shield, and a ventilated cooling path that supports higher thermal margins. The unit carries a one-year warranty from installation or eighteen months from shipment (whichever occurs first). Regular inspection of cooling airflow, connections, and shielding, along with periodic electrical tests, will help sustain performance and reliability.
