ELECTRICAL SWITCHING AND SAFETY SOLUTIONS FOR TUNNELS

Backed by a solid industrial track record since 1944, our company combines decades of sector expertise with the agility of a technology pioneer. Demonstrating our commitment to innovation, we reinvest over 10% of our turnover into R&D, developing cutting-edge load-break switching technology for demanding underground infrastructures.

We offer the most extensive product range on the market, covering an unmatched depth of power ratings through dedicated product lines. Our global leadership is backed by a unique offering: a comprehensive range certified under the European EN 12101-3 standard (F300, F400/120 min, and F600 classifications for smoke extraction), alongside a specific, dedicated range compliant with American (UL/CSA) standards—an exclusive capability that allows us to support major projects worldwide.

The true value of our engineering lies in our mastery of materials technology. We ensure flawless electromechanical performance under overloads in normal conditions, while keeping system integrity and conductivity intact under direct fire exposure, backed by continuous destructive laboratory testing.

We thrive on production flexibility and systematic custom design. We regularly support complex modernization (retrofit) projects across France and Europe, solving critical space constraints by integrating the switch and junction boxes for oversized cables into single compact enclosures. Operating under ISO 9001 and ISO 14001 standards, we deliver the reliability of an established global leader with the drive of an innovation hub.
