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