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.
