Sécheron

What Sécheron does

Sécheron SA is a 147-year-old Swiss privately held manufacturer of electrical protection, switching, and power conversion equipment, headquartered near Geneva and operating as the Sécheron Hasler Group with subsidiaries in India and rail electronics (HaslerRail AG). The company organizes its portfolio into three pillars: Electrical Safety Solutions (ESS) covering pantographs, DC and AC circuit breakers, integrated high-voltage systems (MODBOX, MODFRAME), contactors, disconnectors, earthing devices, and sensors for rolling stock; Traction Power Systems (TPS) encompassing DC and AC substation switchgear under the ESTRA brand and the STELLA protection and supervision family (SEPCOS relays, KEOPS SCADA, SCMS stray current monitoring, and the IOMS SaaS platform); and Power Conversion Systems (PCS) including transformers, rectifiers, inverters, reversible and BOOST converters, automatic assured receptivity units, and energy storage systems.

The core technology base is high-voltage DC and AC electrical protection for railways, anchored in proprietary ultra-rapid (UR) DC circuit breakers with bi-directional and self-tripping capability, vacuum interruption AC breakers with optional Point-on-Wave synchronous switching, and integrated roof/under-frame systems that combine multiple components into certified enclosures. Products are type-tested to EN/IEC and IEEE standards in the company's ISO 17025-accredited Geneva laboratories, supporting homologation for both European and North American rail markets. The technology base extends beyond rail into renewable energy (hydrogen electrolysis, solar, wind, energy storage, nuclear fusion excitation), energy-intensive industries (mining trucks, DC arc furnaces, rolling mills, MVDC grids), E-mobility (EV fast charging), and marine DC grids.

Sécheron sells primarily through a direct enterprise field sales motion targeting railway operators, rolling stock OEMs, and industrial customers, supported by a worldwide after-sales service network offering spare parts, maintenance, retrofits, and digital services. The company runs a project-based quotation model with undisclosed pricing and a growing recurring software revenue layer via IOMS subscriptions. Customers identified include TransN (Switzerland), Lausanne Tramway, Tranvía Metropolitano de la Bahía de Cádiz, and the King of Denmark's battery train program, with the firm operating across at least nine countries in Europe, India, and South Africa.
