Overview

The Hammond Power SK3A0300PK4S is a 300 kVA, three-phase, K-Factor 4 transformer designed for energy efficiency and compliance with DOE 2016 and NRCan 2019 standards. This unit features aluminum windings and a shielded design, making it an ideal solution for applications experiencing harmonic distortion from non-linear loads. Operating at 600V Class, it is configured for 480Y/277V service, providing reliable power distribution. The K-Factor rating of 4 is specifically engineered to handle the increased heating effects caused by harmonic currents generated by equipment such as variable frequency drives (VFDs), LED lighting, and other modern electronic loads. By mitigating these harmonics, the transformer reduces core and winding temperatures, extends insulation life, and prevents premature failure. Its shielded construction further enhances performance by minimizing electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring cleaner power output and protecting sensitive downstream equipment. Manufactured in the US, this transformer offers a robust and compliant solution for industrial facilities, data centers, and commercial buildings requiring stable and efficient power under challenging load conditions. SKU: SK3A0300PK4S.
