Feature → Business Impact → Application: The K-Factor nonlinear design helps mitigate harmonic distortion, reducing overheating, extending component life, and enabling more predictable equipment performance in high-demand facilities. This translates to improved uptime and lower maintenance costs for manufacturing lines and industrial processes, especially where non-linear loads are present. Application: mid-to-large industrial environments seeking reliable harmonic mitigation and stable power delivery. Feature → Business Impact → Application: Vented XFMR construction improves cooling efficiency, enabling safer operation in densely packed switchgear rooms and on-platform installations. The result is lower thermal stress, fewer derating events, and easier compliance with thermal management requirements in space-constrained facilities. Application: data centers, distribution rooms, and automated production cells needing robust ventilation. Feature → Business Impact → Application: 75 kVA three-phase rating provides scalable capacity for evolving loads while preserving compact footprint relative to higher-power substitutes. This supports incremental growth without costly rewrites of power infrastructure and minimizes downtime during upgrades. Application: manufacturing and process industries with variable line loads. Feature → Business Impact → Application: 480-208Y/120V configuration and proven UL Listed safety profile simplify installation and integration with standard facility power architectures, accelerating project timelines and reducing commissioning risk. Application: plant floors, machine builders, and systems integrators deploying new or retrofit transformers. Feature → Business Impact → Application: K13 harmonic control combined with a ventilated design reduces energy waste, lowers cooling requirements, and helps meet regulatory and industry standards for electrical systems. Application: utilities-adjacent facilities and ESG-conscious manufacturers optimizing energy performance.

FAQs
Installation should follow the manufacturer’s guidelines for a vented XFMR with a 75 kVA rating. Plan for proper clearances, secure mounting, correct primary and secondary wiring to 480V and 120V phases, and ensure ventilation pathways remain unobstructed. Verify UL Listed compliance during commissioning and confirm compatibility with existing switchgear and protection relays to minimize wiring errors and downtime.
K13 indicates a higher tolerance to harmonic currents, helping limit overheating and voltage distortion when non-linear loads are present. This improves system reliability and reduces the risk of nuisance trips. In practice, you’ll see steadier voltage profiles on sensitive equipment and better overall power quality in facilities with converters, drives, or other harmonic-generating equipment.
Yes, with its 75 kVA three-phase design and vented cooling, the transformer can support mid-range load profiles typical of data centers and manufacturing lines. Its harmonic mitigation (K13), UL safety certification, and compatibility with 480Y/120V infrastructure help ensure reliable delivery of critical power while maintaining energy efficiency and manageable cooling requirements.
The listed certification is UL Listed, which provides safety validation and helps meet electrical codes and safety standards in many regions. While other certifications are not indicated in the data, the UL Listed status supports regulatory compliance for installation, maintenance, and service, and aligns with common industry expectations for industrial transformers.
Maintenance is typically minimal due to a vented design that enhances cooling and reduces thermal stress. Regular inspection of connections, insulation condition, and ventilation paths is advised. The K13 K-Factor capability helps sustain performance under harmonic loading, contributing to longer service life and lower total cost of ownership for mid-size industrial applications.
