Product environment

Sécheron key multipliers and door locks are manual interlocking devices used by rail vehicle maintenance technicians before they can safely work on high-voltage equipment after all earthing devices have been switched to the “safe” position. Railway car builders, traction propulsion equipment manufacturers, and train operators trust Sécheron key multipliers and door locks for their performance and reliability.

Removing interlocking keys prevents earthing devices from being operated unsafely. Sécheron key multipliers and door locks can be delivered with other Sécheron safety key interlocking devices like pantograph interlocking switches and earthing switches or as part of a complete solution with AC or DC circuit breakers, switching devices, and current and voltage sensors to ensure the electrical safety of the traction chain on AC and/or DC railway vehicles.

All of our components and solutions are backed by Sécheron expert service during all phases of your project. Let us recommend the best solution to meet your needs. Whatever your choice, you can count on efficient support worldwide for the entire lifetime of your product.
