A TECHNOLOGY WITHOUT EQUIVALENT ...

MARECHAL® DECONTACTOR™


The only electrical connector that combines a connector and a switch.
Our unique technology allows you to connect and disconnect electrical connectors from 5A to 250A on load.

A ONE OF ITS KIND DESIGN IN THE WORLD!

BUTT CONTACT ON A SILVER-NICKEL TIP

The MARECHAL® DECONTACTOR™ and connectors are all fitted with butt contacts with silver-nickel tips. They provide exceptional connection quality by eliminating the damage due to electric arcs and to wear seen with pin and sleeve sockets. The silver is an excellent conductor of current even when oxidized. Conductivity is optimal even in the presence of vibration and temperature variation thanks to the pressure of the springs. 

CRIMPED BRAIDS

The MARECHAL® contact uses a crimped braid with a spring which provides contact performance and tolerances superior to pin and sleeve contacts. The flexibility of the braid and the spring allows the base contact tip to always be perfectly aligned with the plug contact tip. These contacts, which are silver and anti-corrosion treated, offer very good corrosion resistance.

ELASTIC LOCK TERMINALS

MARECHAL® contacts are fitted with "elastic lock" connection terminals.

The wire clamp is split and surrounded by a rubber ring. This method allows the tightening force on the wire to be constant. Hence despite the creep of the copper or aluminium, the variations of temperature and vibration, the conductor wire is perfectly connected to the contact terminal. 

SAFETY SHUTTER

DECONTACTOR™ bases are fitted with an interlocked safety shutter which prevents access to live contacts. This shutter only unlocks at the time of connection of the plug into its base. 

Casing made from advanced materials

MARECHAL® range connectors and DECONTACTORs™ have casings made from fibre glass- or metal-reinforced GRP, depending on the models. This choice of material contributes to the excellent mechanical performance and longevity of the socket. 

 

ECONOMY OF INSTALLATION: DUAL-VOLTAGE

With a single base (e.g.: 3 Pnt - 230/400 V) it is possible to feed 3 plugs indifferently:

  • a 3 Pnt - 230/400 V plug
  • a 3 Pnt – 400 V plug
  • a Pnt - 230/400 V plug
This compatibility provides real savings on the installation of these sockets for the user.

BENEFITS

These technical choices provide MARECHAL® connectors and DECONTACTORs™ with unparalleled performance:

  • Absolute safety after thousands of connections/disconnections,
  • The ability to withstand repeated overloads, particularly on power supplies to motors with frequent starting,
  • Perfect operation in the presence of vibration and variations in temperatures,
  • Resistance to shocks, falls and climatic variations,
  • A perfect resistance to corrosion and the most severe chemical agents.

BURSTING WITH FEATURES TO ENSURE YOUR SAFETY

The quality of the material, the design, the assembly and the inspection of each component are at the core of our know-how and the MARECHAL® technology.

Each component provides a precise function that optimizes the performance, safety and sustainability of our sockets and installations.
