Plugs & Sockets

Marechal plugs and sockets (decontactors) provide low voltage power supply for high current and hazardous area (Zone 1 & Zone 2) ATEX power distribution applications – this includes power plugs for electric generator sets, motors, machines, distribution boxes, pumps and electric cabinets.

The range of Marechal plugs and sockets are available in a range of current ratings, switching capabilities, voltage supply and hazardous area certifications (according to ATEX & IECEx) for safe use in potentially explosive atmospheres – this includes oil, gas and petrochem industries.

MARECHAL Live Disconnect Plugs

Decontactor = Plug + Socket + Motor Load Make/Break Switch

Marechal Decontactors can be disconnected under full load for planned maintenance or rapid change out of equipment during plant shoutdowns.

The decontactor from Marechal is supplied with an integral load-break switch offering technical benefits including quality contact, safe disconnection under load, watertight seal (up to IP68) and power supply reliability.

Marechal plugs and sockets are used in various industries globally including mining, oil & gas, offshore, food & drink, shipping and petrochemical as well as other areas that require a guaranteed safe electrical connection.

The Marechal range of ATEX plugs and sockets have automatic watertightness, comply with the relevant standards and can be used in Zone 1 & Zone 2 hazardous areas.

Industrial Power Plugs – decontactors with 16A to 700A current ratings and 1,000 volt power supply.

Marechal Electrical Safety

Load Break Release Button & Safety Shutter

Marechal plugs feature a safety button placed on the upper section of the safety socket enabling the user with a single press of the button to disconnect the equipment up to 250A – no specialist skills or training is required to install the plugs. The plugs can therefore be removed in complete safety – the power outlet installation is safe and does not represent an electrical hazard guaranteeing operating speed and time savings during installation operations or machine shutdown. As an additional feature a safety shutter protects the user according to IP4X/IPXXD – the live contacts are inaccessible behind the closed shutter.
