Mersen Electrical Power offers in the area of power transfer for rail vehicle application market four solutions addressing each one a major function in the power chain: to collect current with third rail Current Collector Devices for powering the bogie, to protect the main traction power cable with Fuses in Cubicle for minimizing the effects of faults or failures, to select with On-Board Switches for connecting the DC power to the power converter and auxiliary system, to reject with Earth Return Current Units for closing the current loop by returning the current to rail.
On-Board Switches are compliant with existing standards. Customization drives the design by Mersen in terms of short-circuit current capability, endurance, low load make/break capacity. High clearance distance between open contact and self-cleaning contacts are key features of Mersen switches.
