Overview

The Hammond Power SK3A0500KK2K is a 500 kVA, three-phase, copper-wound distribution transformer engineered for high-efficiency power distribution in industrial and commercial environments. This DOE 2016 and NRCan 2019 compliant unit meets stringent energy efficiency standards, reducing operational costs while maintaining reliable performance. The transformer features a 480D primary (PV) and 480Y/277 secondary (SV) voltage configuration, optimized for 600V class operation. Its shielded design minimizes electromagnetic interference, making it ideal for environments with non-linear loads that generate harmonic distortion. The SK3A0500KK2K is manufactured in the USA and carries the UNSPSC code 39121001. Key specifications include a k-factor of 4, a heavy-duty ventilated Type 3R enclosure, and compliance with UL 1562, CSA C22.2 No. 47, and seismic standards (IBC 2018/ASCE 7-16). The transformer weighs 6,400 lbs (2,910 kg) and measures 84" (2134 mm) in width, 54" (1372 mm) in depth, and 91.5" (2325 mm) in height. It is designed for floor mounting with optional wall/ceiling mounting kits available. The unit includes factory-installed grounding lugs, outward-facing mounting holes, and separate high/low voltage terminal boards for safe and efficient wiring. With a typical impedance of 3% to 6.5%, this transformer delivers stable power delivery while meeting modern energy efficiency regulations.
