Improve Electrical Safety & Power Reliability

Inertia and a resistance to change prevents progress even where the allure or reason for the initial attraction has long since past.

Working with Marechal, a world-leading manufacturer of industrial plug-socket assemblies, Thorne & Derrick can provide increased safety and improved reliability compared to the traditional “hard-wiring” approach to low voltage power distribution using their innovative Decontactor technology.

The decontactor

DECONTACTOR = PLUG + SOCKET + integral switch disconnector

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

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.

Marechal plug-socket assemblies can 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.

Electrical power can be controlled and distributed up to 1100V, 660Amps using the Marechal P66 high voltage connector for industrial applications.

Anatomy Of The Decontactor

The Marechal decontactor is a plug and socket with an integral load-break switch – this unique design offers various benefits :

contact quality
safe disconnection
automatically watertight
cost reduction due to dual-voltage
robust and reliable
