Sécheron Hasler Group

We've been at the forefront of electrical safety and power conversion for over 140 years, combining Swiss engineering precision with a commitment to sustainable transportation. Our team designs and manufactures the critical components that keep railways safe and efficient - from high-speed DC circuit breakers and sophisticated protection relays to complete traction power substations. What started as a specialized railway equipment manufacturer has evolved into a global operation with more than 1,300 employees across multiple continents, all focused on delivering reliable solutions that power the shift toward emission-free mobility and renewable energy integration. Our expertise extends well beyond traditional rail applications. We're applying our high-power electrical systems to support hydrogen production, mining electrification, marine vessels, and emerging DC grid infrastructure. Every product we create goes through rigorous testing and certification because we understand that in safety-critical applications, there's no room for compromise. Whether it's designing custom protection systems for a metro line or developing next-generation converters for green hydrogen electrolysis, we approach each project with the same dedication to quality and innovation that has defined our company for more than a century.
