About LS Electric

Performance Certainty — an engineering standard, not a marketing claim.

LS Electric (formerly LS Industrial Systems) is one of Korea's largest electrical manufacturers with over 70 years of production history. Their Cheongju and Gumi factories build products to IEC standards that are certified by KEMA, CB, and marine classification bodies — third-party tested, not self-certified.

TROPAC has stocked LS Electric since the brand's introduction into the Australian market. When you need coordination data, trip-unit selection advice, or a direct line to the LS Electric technical team, our PACs handle it.
