Marechal Decontactor Technology

A Decontactor is a plug and socket outlet system with an integrated power switch permitting safe connection and disconnection of electrical equipment with “Plug and Play” simplicity and includes a integral load break switch which has many benefits such as:

Safe electrical disconnections for Low Voltage Power Distribution
High temperature, high current and hazardous area certified plugs
Automatically watertight plug/socket assembly
Cost reduction due to dual-voltage systems
Robust and reliable Decontactor alternative to conventional plugs and sockets
Electrical connection and contact quality

Did you know? The Decontactor is the only electrical connector that combines a connector with a switch. Marechal’s unique technology allows users to connect and disconnect electrical power supply from 5Amps to 250Amps on load. The below video shows that Marechal plugs combine electrical safety and reliability for power control and distribution in industrial and hazardous areas.

Below is the full product offering of Industrial & Hazardous Areas Plugs & Sockets ranging from 20 Amps to 400 Amps.
