Secheron Disconnectors

Sécheron disconnectors ensure a wide variety of functions in AC and/or DC railway vehicle traction chains. Railway car builders and railway operators seeking performance, reliability, and low maintenance turn to us for the highest level of safety and comprehensive, coherent solutions that coordinate seamlessly with other Sécheron switching and protection components for traction circuits.

Secheron’s RS, IS, XMS, and BW disconnectors for rolling stock cover off-load disconnect, disconnect and earthing, and traction circuit selection and reconfiguration. They are available with or without making capacity and in single and multi-pole versions for outdoor roof (with or without roof cut-out) and indoor installation and cover rated insulation voltages up to 27.5 kVAC or up to 4.8 kVAC/DC and rated currents from 750 A to 4,000 A.

These disconnectors can be delivered on a stand-alone basis or integrated into Secheron’s smart, compact MODBOX® high-voltage enclosures with other high- and low-voltage functions for the electrical safety, measurement, and control of the traction chain.
