Plug & Socket with Integral Load-Break Isolating Switch 

Marechal switch rated plugs and sockets (decontactors) are ideally suited for harsh mining and tunnel environments including a range of metal casing plugs and socket-outlets up to 600A - Marechal decontactors reduce downtime compared to hard-wiring.

Typical mines, quarries and tunneling applications:

  • Marechal DS plugs up to 250A for feeders
  • DB plugs up to 30Kw for screeners
  • DSN plugs rated at IP54 to IP66 for conveyors
  • PF plugs up to 600A for generator power supply
  • DS plugs for float pumps and Marechal decontactors for process equipment including crushers, cutting machines, motor control centres and extruders.

The harsh environment in mines and quarries is well suited to the Marechal decontactor's reliable connection, robust build and safety features.

Marechal plugs feature butt contacts with silver-nickel tips which are an excellent conductor and are corrosion resistant.

Marechal plugs heavy duty design is shock resistant (Ik08/Ik09) and environmentally sound (-40 °C to +60 °C) - Marechal plugs and sockets are fit-and-forget connectors.

Thanks to its integral load-break isolating switch mechanism, the Marechal decontactor socket allows users to connect and disconnect electrical equipment safely up to 250 A.

A release button cuts the power and de-energises the Marechal plug before it can be removed.

Even in the event of a short-circuit, the Marechal decontactor guarantees user safety and eliminates any electrocution hazard.

For Ex environments Marechal offer ATEX approved plugs and sockets with "de" protection mode up to 200 A. 

Marechal Electric pioneered the use of high performance, silver-nickel butt contacts in electrical plug and socket systems (decontactors), which are now available for applications from simple compact multi-pin to heavy duty 600A plug connections.

Marechal technology is used across a range of demanding environments such as the food and drink, nuclear power, heavy industry, infrastructure and ATEX hazardous area sectors.

Marechal decontactors are an effective alternative to both hard-wired equipment and pin/sleeve type contacts, the decontactor is a highly flexible method of connecting and disconnecting electrical equipment at the press of a latch – safely.

Marechal Electric brought the decontactor, the high performance industrial plug connector with integral AC21 switch, to the electrical market.
