FAQs
Plan for floor or wall mounting using the FR943 frame within a NEMA 2 indoor enclosure. Ensure space for a 31.5 in long, 34.5 in wide, and 51 in tall unit weighing roughly 1424 lb, with access to 283B wiring. Consider guarding against dust and moisture, and verify proximity to the 480 V primary supply and 208Y/120 V secondary loads.
The unit is a three-phase, 112.5 kVA transformer operating at 60 Hz, with a primary of 480 V and secondary of 208Y/120 V. It uses copper windings, features a 220 °C insulation, and includes a K-Factor of 13 for nonlinear loading. It is UL Listed and DOE 2016 Efficient, with a NEMA 2 enclosure and a FR943 frame.
Yes. Its K-Factor nonlinear design, high-efficiency DOE 2016 rating, and robust NEMA 2 enclosure make it suitable for continuous operation in indoor factory environments. The copper windings and 112.5 kVA rating support reliable power delivery to controls and motors while managing heat and harmonics effectively.
UL Listed certification confirms compliance with safety standards, while DOE 2016 Efficient indicates adherence to energy efficiency rules for low-voltage distribution transformers. These certifications help meet regulatory requirements, reduce energy costs, and simplify procurement for regulated facilities.
The unit includes a one-year warranty from installation (or 18 months from shipment), minimizing risk during initial operation. Energy efficiency reduces operating costs over time, and the durable NEMA 2 enclosure plus copper windings lower maintenance requirements and downtime in busy facilities.
