Railway grounding device

phase short circuit

Description
In the event of a malfunction, metro, subway or monorail vehicles must be de-energized immediately to protect sensitive onboard equipment and to allow safe passenger evacuation. The short-circuiter for 3rd-rail applications is a pneumatically actuated switch that creates a short circuit to de-energize all relevant systems, including the third rail. It is supplied as an optional accessory for 3rd-rail current collectors.

Key benefits

• Protects vehicle electronics and passengers by rapid de-energization
• Reliable actuation via pneumatic release
• Immediate disconnection of the live third rail
• High-current resistant design suitable for rail applications

Additional information
Offered as an optional accessory for 3rd-rail current collectors; engineered to reliably de-energize vehicle systems and the third rail in fault conditions.
