Current collector devices Bottom ant top contact The collector is fastened on the vehicle off-center from the rail and a pressure system maintains contact vertically, from top to bottom or bottom to top. With this type of device all three free surfaces of the conducting rail can be tapped. Integrated or separated fuse box. Manual or power retraction. Tianjin Lateral contact Single or two-pole. The pressure system maintains contact horizontally in the rail’s axis. Beam-mounted contact Collectors mounted on insulated beam and air operated. Specific device for tram application Bordeaux

Power Transfer TO PROTECT Fuse boxes Bogie mounting Insulating, self-extinguishing fuse-boxes withstanding shocks and vibrations in compliance with current standards. Approved by many manufacturers. Lightning arresters Mersen proposes to use a zinc oxide varistor combined with a fuse and an electric signalling system. Thanks to this, it is now possible to vastly improve the quality of power line protection with lessened peak let-through when overvoltages occur. Indoor and outdoor use. Insensitive to vibrations. On-board or fixed installation Disconnecting fuse

for Rail Vehicles TO SELECT Disconnectors Change-over switches MERSEN offers a wide cutomization-driven modular range of disconnectors and change-over switches specially suitable for electric traction on-board equipment. Manual activation All these devices are compliant with current standards with adapted technical performances (short-circuit current capability, endurance, small load make / break capacity), long distance between open contact and self-cleaning contacts. Metro application Inspiro Warsaw Motorized activation Shanghai Montreal Rotary switches

Earth Return Current Units ERCUs, axial or radial, are installed on axles to provide an effective shunt around the bearings. Velaro China (High-speed train, 600 A) EP20 Velnii Russia (4 brushes 20x40) On recent tramway rolling stock, the device is mounted insulated in the hub and returns the current to the rail via brushes in contact on a track. A watertight ball bearing is built into the unit to ensure rotation of the whole with the disc.
