Product environment

Sécheron brings decades of experience designing and manufacturing high-voltage AC components and solutions. The builders and operators of trains, high-speed trains, locomotives, and EMUs on 15 kV and/or 25 kV railway networks turn to us to ensure the electrical safety of their traction circuits.

Starting with our main AC circuit breaker, we bring railway car builders and railway operators a wide range of solutions from stand-alone main AC breakers (MACS & BVAC) to multifunctional units (MACS) with integrated earthing switch, surge arrester or disconnect switch. To support car builders and operators to mitigate against AC rail vehicles’ inrush currents and Electromagnetic Interferences generated by switching transients when closing AC circuit breakers, Sécheron has designed a unique Point-on-Wave/synchronous switching function that can be installed on our AC circuit breakers type MACS. This optional function enables to achieve a synchronous repetitive and accurate closing or/and opening of the MACS with a predefined phase angle of the line voltage.
For car builders seeking high performance, reduced engineering work and easier vehicle manufacturing combined with lower maintenance, we can also provide turnkey solutions, integrating our AC circuit breakers into our smart, compact MODBOX®-type high-voltage enclosures with other high- and low-voltage electrical safety, measurement, and traction chain control components.

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.
