ENSURE SAFETY FOR PERSONNEL ...Decontactors’ features ensure safety by preventing access to live parts, byproviding superior electrical connections that do not deteriorate with wear oroxidisation and by allowing users to make and break connections safely - evenin wet or during overload conditions.

Connect with confidence & disconnect with safetyThanks to its integral load-break isolating switch mechanism, the decontactorsocket allows users to connect and disconnect electrical equipment safely up to250 A: a release button cuts the power and de-energises the plug before it can beremoved. Even in the event of a short-circuit, the decontactor guarantees usersafety and eliminates any electrocution hazard.

Automatic watertight sealOur decontactors are automatically watertight (high pressure washing, temporary immersion) just by inserting the plug or byclosing the socket lid when you remove the plug. There is no need to turn any sealing ring!

Robust and reliableThe decontactor has silver-nickel butt contacts which guarantee superior electrical performance and environmentally sound(-40 °C to +60 °C) Its glass-fibre reinforced polyester or metal housings provide excellent resistance to shock (IK08 / IK09) UV andcorrosion.

Endurance to over currents and 100% duty factorDecontactors can carry significant overloads: 2 to 8 times more than it’s required by the standard IEC 60309-1. It supports avoltage up to 1 000 V a.c. and up to 250 V d.c., permanent or alternating current without damages or overheating.

Marine certification of the DSN/DXN/SP/SPX ranges by Bureau Veritas is pendingMarechal connectors are already used in marine applications for more than 20years, especially for navy and Oil&Gas projects.

Marechal’s DECONTACTOR™ ideally suited

... & SIMPLIFY MAINTENANCEDecontactors allow fans, pumps, heaters, cutting/welding tools and otherequipment to be connected safely with plug and play simplicity. Fitters caneasily replace or service visibly isolated equipment without needing an electri-cian on site.Equipment replacement times are significantly reduced, worker exposure toharsh environments is minimized and re-wiring errors are eliminated.

Focus on vessels, ports,marinas & shipyards

DECONTACTORTM, a plug and socket technology that solves your connection problemson ports, shipyards and on board….

Its robust design guarantees durability and reliability. Its automatic watertight seal and load-break disconnectioncapability means safety for the workers.

Weather conditions and corrosive seaenvironmentWith so much water, salt and humidity, brass copper contacts sufferfrom oxidization and thus failure.

Decontactor advantageOur design uses silver-nickel butt contacts which resist to corrosion.The decontactor is automatically IP66/67 watertight, it resists waterjetting and temporary immersion.

Crane connectionsSome process equipment such as a crane is moved from one ship toanother.

Decontactor advantageThe decontactor’s integral load-breaking capability simplifies con-nection and disconnection procedures, it can be easily operated byone single person, saving time and money.

Harsh environment on shipyards Salt corrosion, humidity, temperature change and mechanical shockslead to bad connection and overheating, and ultimately failure.

Advantage of butt-contact technologyThanks to its butt contact technology and superior material, the decon-tactor resists shocks and corrosion. Power supply is always availablewhen needed, even after years in use.

Durable equipment and cost savingPlugs and sockets often need to be replaced frequently due to condi-tions of use.

Decontactor advantageThe decontactor’s robust casing, frictionless contact technology, pro-vide excellent resistance to temperature changes (-40 °C to +60 °C)and shocks (IK08 / IK09) and corrosion. After a short period, you willsee your maintenance expenses decrease!

Effortless operation To connect or disconnect a plug and socket with 250 A or more needsmuch physical effort, especially when corrosion and overheating hasdeformed the sleeves in the socket.

Advantage of butt-contact technology Marechal’s butt-contact technology is used on PF plugs and sockets(up to 600 A) and SP single pole connectors (up to 700 A and more).The technology and the superior materials used prevent heating andcorrosion. Connection remains effortless even after years in use.

Public safetySockets-outlets in public area can be misused and could lead toinjuries for adults and children.

Decontactor advantageAccess to the electrical contacts is protected by IP4X protectionagainst foreign objects and hazardous parts. The socket-outletcontacts are kept clean and inaccessible even when the lid is opened.

Oil and gasIn hazardous area atmospheres, the ATEX regulation dated 23rdMarch 1994 and 199/92/EC require certified equipments.

Advantage decontactor – ATEX DXN decontactor is EX approved for zone 1 and 2. In a compact designit guarantees 10 000 operations.

Note Cost Saver: An extra advantage isthat DXN type ATEX plugs can fit intoindustrial DSN sockets negating theneed to install the more expensiveATEX socket is the safe area workshop.Of course the industrial DSN plugcannot fit the ATEX socket.
