FAQs

For proper installation, ensure adequate ventilation and clearance for the 33.97 in length, 62.91 in height, and 29.97 in width footprint. Mounting should accommodate the 924 lb weight and allow access to the tap settings: 1 at +5%, 2 at -5%, 2 at +2.5%, and 4 at -2.5%. Verify UL Listed compliance and NEMA TP-1 conditions in the panel design.
The K-Factor nonlinear design mitigates heat and loss under nonlinear loads by managing harmonic currents, reducing voltage distortion and overheating. This improves transformer efficiency and reliability in drives, inverters, and other non-sinusoidal loads typical in automation environments, helping maintain panel uptime and longer equipment life.
Yes. The transformer provides a 120/240 V secondary from a 240 x 480 V primary, suitable for data centers and robotics that need dual-winding outputs with reliable regulation. Pairing with aluminum windings and electrostatic shielding further supports consistent performance in environments with electrical noise and temperature fluctuations.
Key certifications include UL Listed safety for electrical components and NEMA TP-1 compliance for efficiency and performance standards in distribution transformers. The catalog notes also emphasize NEMA TP-1 efficient operation, ensuring regulatory alignment for industrial projects and safer, compliant installations.
A one-year warranty (or 18 months from shipment) plus Eaton’s standard policy supports maintenance planning. The aluminum coil construction and robust frame enhance durability with minimal routine maintenance. The unit’s 150°C rise capability and electrostatic shielding reduce the risk of failures in harsh environments, contributing to lower replacement and downtime costs over the transformer’s life.
