Compact HV integrated solutions
for rolling stock
Type MODBOX®
General information
MODBOX® is a compact and modular ‘’plug & play’’ solution,
for a smart and safe integration of high voltage components on
traction vehicles running on AC and DC networks.
Sécheron switching and protection components (AC circuitbreakers, DC circuit-breakers, contactors, disconnect switches)
are primarily integrated in MODBOX®, completed with devices
from first class suppliers for the other functions necessary to the
application.
Built on a standard platform of rolling-stock-dedicated aluminium
enclosure, MODBOX® is configured and engineered to address
each project particular requirements for both integrated
functionalities and interfaces to the vehicle.
MODBOX® is the solution selected by car builders for hundreds
of trains, including high speed trains, running under 3kVDC and
25kVDC networks worldwide.
Designed to solve critical issues met with high voltage components
set individually on vehicles’ roof, MODBOX® offers significant
added value for both car builders and vehicle operators.

Main benefits
Modularity
MODBOX® is a modular platform suitable for AC and DC vehicles, offering different sizes (MODBOX® Small, MODBOX® Medium,
MODBOX® Large), depending on the integration scope , as well as variants for roof or under-frame installation.
Plug & Play
One single plug and play unit for most of AC or DC high voltage components, roof or under-frame mounted. Shipped fully equipped and
tested, MODBOX® is convenient to source and ready to be installed.
Compactness
Overall roof/under-frame volume for high and low voltage components is largely reduced with MODBOX®, and no more space for cable
ducts is required between the roof and the car’s ceiling.
Safety
Metal clad enclosure validated by Finite Element Analysis for compliance with EN12663-3, and tested for vibrations & shocks according
to IEC61373. EMC proven, and achieving an IP56 protection index, MODBOX® complies with EN50124 insulation requirements with a
rated impulse voltage of 125kV (150kV in option) for AC versions, and 30kV for DC versions.
Protection for harsh environmental conditions
Protecting high voltage roof equipment against dust, snow, ice and sand, MODBOX® simplifies design constraints for car builders, as well
as it guarantees train operators a longer life time and a higher availability of their rolling stock.
Noise reduction
MODBOX® reduces considerably airborne and structure noise improving comfort for passengers.
High added value
Compared with ‘’stand-alone’’ components solution, MODBOX® reduces significantly project management tasks as well as engineering
and manufacturing risks, while optimizing project overall costs.
Reduced Total Cost of Ownership
Protected with MODBOX® against accidental and meteorological/environmental impacts, high voltage roof mounted components can
afford longer maintenance intervals.

Product integration
The quality and the reliability of MODBOX® rely on several key factors, among which the deep know-how needed to integrate together
high voltage components in a compact metal enclosure, as the quality and performances of these integrated components. In both areas
and for decades, Sécheron has been developing a unique expertise, highly valued by our customers worldwide, in the fields of 15/25 kVAC
and 1.5/3 kVDC. Naturally, Sécheron standard proven components are firstly used in AC & DC MODBOX®, completed with equipment from
first class suppliers.
