Sécheron Hasler Group designs and manufactures high-power electrical safety and power conversion components deployed in railway traction systems and other demanding DC environments. The product line spans high-speed DC circuit breakers, sophisticated protection relays, complete traction power substations, and custom protection systems for metro lines and similar infrastructure. More recently, the company has developed next-generation converters targeting green hydrogen electrolysis and related renewable energy integration applications.
With over 140 years in electrical safety and power conversion, the company operates across multiple continents with more than 1,300 employees. Technical domains include high-power electrical systems design, DC circuit breaker engineering, protection relay development, and traction substation integration. The work spans the hardware and control boundaries of safety-critical systems - circuit interruption dynamics, relay coordination, substation power electronics - where certification requirements and real-world fault conditions constrain design choices.
Industry verticals extend beyond rail to include mining electrification, marine vessels, and DC grid infrastructure. Engineering culture emphasizes rigorous testing and certification appropriate to safety-critical applications, with Swiss engineering precision cited as a core operational value. For robotics engineers, the relevance lies in the intersection of high-power actuation, real-time protection logic, and the control systems that govern power conversion under variable load and fault conditions.
