The range of Marechal plugs and sockets are available in a range of current ratings, switching capabilities, voltage supply and hazardous area certifications (according to ATEX & IECEx) for safe use in potentially explosive atmospheres – this includes Zone 1 & Zone 2 (Gas) and Zone 21 & Zone 22 (Dusts).
MARECHAL Live Disconnect Plugs
DECONTACTOR = PLUG + SOCKET + INTEGRAL SWITCH DISCONNECTOR
A Decontactor® is a plug and socket outlet system with an integrated power switch permitting absolutely safe connection and disconnection of electrical equipment with plug-and-play simplicity. The Marechal decontactor is a plug and socket with an integral load-break switch – this unique design offers various benefits :
- contact quality
- safe electrical disconnection
- automatically watertight plug/socket assembly
- cost reduction due to dual-voltage system
- robust and reliable alternative to conventional plugs and sockets
Marechal Decontactors can be safely disconnected under full load for planned maintenance or rapid change out of equipment during plant shutdowns. The decontactor from Marechal is supplied with an integral load-break switch offering technical benefits including quality contact, safe disconnection under load, watertight seal (up to IP68) and power supply reliability.
Marechal plugs and sockets are used in various industries globally including mining, oil & gas, offshore, food & drink, shipping and petrochemical as well as other areas that require a guaranteed safe electrical connection.
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. The plugs can therefore 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.
