Overview

The Hammond Power SK3A0075PK3K is a 75 kVA, three-phase, K-Factor distribution transformer designed for superior energy efficiency and compliance with DOE2016 and NRCan 2019 standards. This transformer features a K-Factor of 13, making it an ideal solution for mitigating harmonic distortion commonly found in non-linear loads such as those generated by variable frequency drives (VFDs) and other electronic equipment. It operates with a primary voltage of 600D PV and a secondary voltage of 480Y/277V, at a standard frequency of 60 Hz. Constructed with copper windings for exceptional conductivity and long-term durability, this unit also includes shielding for enhanced performance and protection against electromagnetic interference. Manufactured in the US, the SK3A0075PK3K is built to rigorous standards, ensuring reliable operation in demanding industrial environments. Its robust design and energy-efficient characteristics contribute to reduced operational costs and improved system reliability. The transformer is suitable for applications requiring robust power quality management and compliance with energy efficiency regulations. Key specifications include a 75 kVA rating, three-phase operation, copper wound construction, and a K-Factor of 13. The primary voltage is 600D PV, and the secondary voltage is 480Y/277V. The series is SK3A. The approximate dimensions are 28.3 inches in width, 27 inches in depth, and 36 inches in height, with an approximate weight of 530 lbs (240 kg). It features floor mounting as standard, with an optional wall/ceiling mounting kit available. The enclosure is a heavy-duty ventilated Type 3R, finished in ANSI 61 Grey. It meets NEMA ST-20 sound level standards and includes features like factory-installed grounding lugs, outward-facing mounting holes, and separate high and low voltage terminal boards for safe and easy wiring. The insulation system is rated at 220°C with a 150°C rise. This transformer is UL Listed (File: E112313) and CSA Certified (File: LR3902).
