FAQs
The transformer supports floor or wall mounting with a rugged NEMA 2 enclosure suitable for indoor use. Installers should follow standard clearances for ventilation and service access, connect to the 283B wiring, and verify proper alignment with WS61 weather protection if applicable. The unit’s 33.5 in depth, 60 in height, and 38 in width should be planned into the equipment layout to ensure serviceability and safe operation.
The N48M47F1216 is a three-phase transformer with a 480 V primary and a 480Y/277 V secondary, rated at 112.5 kVA. It operates at 60 Hz and provides versatile voltage conversion suitable for mid-size industrial loads and automation panels, enabling reliable, clean power delivery to critical equipment.
This transformer is UL Listed and designed to meet DOE 2016 efficiency requirements (10 CFR Part 431). It also features a NEMA 2 enclosure, supporting indoor protection standards. These certifications help ensure compliance with electrical safety and energy efficiency mandates common in manufacturing and processing facilities.
K-Factor 13 indicates resilience to harmonic-rich, nonlinear loads, improving power quality and reducing overheating risk under distortion-heavy conditions. In practice, this means better reliability for drives, inverters, and other nonlinear loads common in automation lines, with lower stray losses and fewer nuisance trips in panel boards.
The DOE 2016 efficiency alignment lowers energy consumption, directly reducing operating costs. With a robust NEMA 2 enclosure, aluminum windings, and optional electrostatic shield, maintenance intervals can extend and downtime can decrease due to fewer field failures, delivering lower total cost of ownership and improved production uptime.
