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.

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.

  • contact quality
