FAQs
This transformer measures 24 in depth, 30.5 in width, and 36.88 in height, weighing 658 lb, so ensure a protective, well ventilated location with adequate clearance per electrical codes. Install on a solid, level surface, plan for forklift access, and provide safe, dedicated supports for loading and wiring connections. Use proper enclosure rating and maintain ventilation around the vented assembly.
The unit provides primary 480 VAC and secondary 208Y/120 VAC in a three phase configuration. This influences bus connections, panel wiring schemes, and neutral grounding. Ensure correct termination, adhere to NEC guidelines, and verify protection devices and conductor sizing for your distribution panel.
K13 indicates a nonlinear transformer design optimized for harmonic currents, improving voltage regulation and reducing winding heating under distorted loads. This enhances reliability for drives, welders, and other equipment drawing nonlinear current, helping meet power quality requirements and reducing maintenance demands.
Data centers, manufacturing lines, robot cells, and process industries gain from the 45 kVA three-phase capability, robust cooling, and a compact footprint. It reduces the number of transformers required, lowers energy losses, and simplifies panel design, delivering lower total cost of ownership in space constrained, high-demand environments.
The N48M28F4521LS45 is UL Listed, confirming compliance with recognized safety standards for industrial transformers. For maintenance, perform regular thermal checks, inspect vented cooling paths, confirm clean air flow, and verify connections per Eaton guidelines to sustain reliability and compliance during operation.
