Sécheron possesses decades of experience designing and manufacturing high-voltage DC electrical safety components for rail vehicles, traction power substations, and energy-intensive industries. Our comprehensive range of high-speed DC current-limiting circuit breakers covers power ratings from 1,000 A to 8,000 A and from 750 VDC to 3,600 VDC.
Our UR series DC circuit breakers can be delivered as standard components or integrated into custom solutions for more efficient integration into your rail vehicles. Sécheron can also provide turnkey solutions, integrating our DC circuit breakers into our smart, compact MODBOX®-type high-voltage enclosures with other high- and low-voltage electrical safety, measurement, and traction chain control components for locomotives, trains, metros and Light Rail Vehicles (LRV).
For DC traction power substations, the UR series is the widest range of DC circuit breakers on the market, protecting the overhead contact lines and third rails that power DC rail vehicles. These breakers can be delivered with Sécheron disconnect switches and contactors.
Sécheron can also provide UR-type DC circuit breakers for energy storage systems, DC drives for steel and paper plants, power plant generator static excitation systems, electric mining haul truck drives, marine vessel cycloconverters, and more.
