Sécheron brings decades of experience designing and manufacturing electrical safety components and systems for the traction circuits powering trains, high-speed trains, locomotives, and EMUs on AC or DC rail networks. Car builders seeking high performance, reduced engineering work and easier vehicle manufacturing combined with lower maintenance have placed their trust Secheron’s MODBOX® enclosure for thousands of rail vehicles running on 1.5 kVDC, 3 kVDC, and 15 kVAC, 25 kVAC networks worldwide.
The Sécheron MODBOX® enclosure includes AC or DC circuit breakers and various high- and low-voltage components. The compact, smart enclosure ensures safe and efficient integration of high-voltage components in vehicle roof vehicle under-frame or vehicle indoor installations. Each MODBOX® is engineered and configured to meet the needs of each individual project, taking into account integrated functions and interfaces with the vehicle. Secheron primarily use their own components and can include other devices from best-in-class suppliers to provide turnkey solutions.
For a high performance and low maintenace solution, the main features include:
AC applications 15 kV (16.7 Hz) and/or 25 kV (50 Hz or 60 Hz)
DC applications 1.5 kVDC and/or 3 kVDC
Thermal current up to 630 A (AC) or 3200 A (DC)
Main integrated high voltage functions: circuit-breaker, surge arresters, current & voltage measurements, earthing switch, line disconnector, line & charging contactors with charging resistor, and others
