Product environment

Sécheron XMS and BW high-voltage modular indoor disconnect switches can be used as disconnector or change-over switches on rail vehicles and in other industrial applications.

Our XMS indoor disconnect switches can be configured as single-pole pantograph disconnectors for railway Electrical Multiple Units (EMUs) running on 1.5 kVDC and/or 3.0 kVDC networks, as single- or double-pole traction circuit reconfiguration switches for multisystem vehicles, and as 3-pole motor disconnectors. XMS disconnectors can be delivered on a stand-alone basis or integrated into Sécheron’s smart, compact MODBOX® high-voltage enclosure with other high- and low-voltage functions to ensure the electrical safety, measurement, and control of the traction chain.

Our BW indoor disconnect switches feature a modular, linear design that can accommodate different numbers of moving contacts and high-voltage terminals, enabling a wide range of configurations and applications. BW switches are mainly used to select or change the configuration of traction or/and auxiliary circuits.

All of our components and solutions are backed by Sécheron expert service during all phases of your project. Let us recommend the best solution to meet your needs. Whatever your choice, you can count on efficient support worldwide for the entire lifetime of your product.
