Agriculture and construction vehicles today have
an important number of functions which have
reduced the already limited installation space available.
At the same time, they require suitable solutions to
control and distribute power for increased loads.
Thanks to the expertise acquired during the years
developing and manufacturing electromechanical
solutions mainly for cars, MTA has developed the
C-MEC 138, a modular electrical centre in charge of the
distribution of power and the protection of the primary
electrical services, specifically designed for off-highway
vehicle cabin compartments.
Plug and play
The C-MEC 138 is a plug and play product produced with
the PCB (printed circuit board) logic and press-fit assembly.
It is an innovative solderless connection technology where
the contact between the press-fit pin and the wall of the
hole is gas-tight, ensuring optimal electrical contacts even
in the presence of strong vibrations.
The C-MEC 138 enables an integration of all the
functions in one piece, thus eliminating the need of
different modules and associated wirings. The vehicle is
therefore lightened from costly and heavy modules and
cables, the wiring layout simplified and the assembly
time reduced. This helps meet the compactness, weight
and cost reduction required by OEMs.
Customise for application
The C-MEC 138 has a rational design and is evidence of
MTA’s aim of offering off-the-shelf products that can be

customised by the OEM for the specific application they
are intended for.
The solution is composed of a bottom cover that
always remains the same; the PCB; the fuse/relay mask;
two studs inserted with press-fit technology, and the
connectors, unconnected from the mask.
It has three customisable levels. Soft level means the
customer can change the fuses and keep the connectors
and the existing PCB. With medium level if the customer
needs to change the scheme, with a very small
investment and very short lead times, he can change the
PCB too. Lastly at the high level if both the PCB and the
contents do not correspond to the customer’s needs, the
PCB and the mask can be redesigned. The changing of
the latter, not having integrated connectors, will require
a relatively simple mould, with reduced costs and time.
Easy installation
The C-MEC 138 is ideal for new applications and for
those that already use an MTA 5-way frame; they are in
fact interchangeable having the same interaxes, while
the C-MEC 138 has a reduced height which allows space
saving in the cabin compartment. Quick and easy to
install vertically and horizontally, the Modular Electrical
Centre has an IP20 protection degree, can operate in
temperatures between -40° C and +85°C and is
compatible with both 12 V and 24 V electrical
architectures. iVT
