Equipping water treatment or sewage treatment sites with MARECHAL® outlets ensures the longevity of your electrical installations and means significant time savings in maintenance operations. Connections are resistant to outdoor conditions and comply with electrical standards.
The connection and disconnection of plugs can be done in complete safety by unskilled operators without the need to isolate the power first.

DECONTACTOR™ has an AC-22/AC-23 breaking capacity which complies with switched isolator standards. There one decontactor unit can used in place of a plug and socket  and local isolator switch. Operators can therefore easily connect and disconnect the plug under load without having to undergo lengthy isolation procedures.
DECONTACTOR™ plugs are built with high quality materials. Silver-nickel contacts, stainless steel hardware, and chemical resistant housings all help withstand corrosion caused by the hydrogen sulfide gases usually found in wastewater environments.


  • Ensuring safety of both staff and premises
  • Electrical continuity both day and night
  • Powering mobile installations
  • Powering pumps, mixers, aerators, motor controls, crushers, compressors, generators

Solutions to your needs

Connection quality and life expectancy 24/7 365 days per year
MARECHAL® products are fitted with spring-loaded contacts providing a permanent and durable contact.
The silver-nickel tipped contacts provide exceptional connection quality and excellent resistance to wet and corrosive environments, even after years of use.

IP66/IP67/IP69K sealing
The reinforced IP66/IP67 watertightness is achieved automatically upon connecting the socket or closing the lid.
It enables the product to be used in extermely wet or dusty environments. Some of our plugs are available up to IP69k for high-pressure cleaning at 100 bar and 80 °C.

Fast and safe connection under any circumstances
The socket latch holds the plug in the socket against the force of the internal springs. This ensures the plug is watertight and that the appliance will start up properly. When the plug is removed from the socket, the safety shutter closes to prevent access to live parts.

DECONTACTOR™ technology: tested safety
• A socket with built-in isolator switch in a compact unit
• Simply pressing the button cuts off the current and eliminates all risk of electrical arcing.
• The plugs then eject automatically and the appliance is off-load.
• The safety of operators is guaranteed at all times.

DECONTACTOR™ From 20 A to 250 A 
The DSN/DS range spans currents from 20 A to 250 A, making it our largest and most complete DECONTACTOR™ range.. Socket-outlets and connectors are available in GRP or metal and offer a large array of options like padlocking, keying systems and auxiliary contacts.

Thanks to their silver-nickel tipped contacts, the DECONTACTOR™ plugs are designed to withstand significant and repeated overloads. Therefore they are especially suited for reliable motor connections even with frequent re-starting.

PF HIGH-CURRENT PLUGS AND SOCKET-OUTLETS - 315 A / 400 A / 500 A / 600 A - 1,000 V
Our PF range can accommodate up to six auxiliaries and two pilots, is IP66/IP67 watertight (standard), and has an electromechanical lock-out system, for maximum safety and water protection. The metal casing offers IK10 shock resistance and is well-suited to connections for heavy equipment and generators for mining and tunneling operations.
