PLUGS & SOCKETS WITH AN INTEGRATED POWER SWITCH
Decontactor = Plug + Socket + Motor Load Make/Break Switch
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.
Marechal Decontactor – Benefits Of Marechal Electric Plug & Socket Assemblies
Load-break Release Button
A button located on the Marechal safety socket enables the operator, with a single press of the button, to live disconnect the electrical equipment up to 250A – no specialist training or skills are required ensuring the plug can be removed in complete safety without electrocution risk to the user.
Marechal plugs and sockets guarantee operating speed and time savings during installation, operations or machinery plant shutdown where rapid turnaround of power distribution is required.
Marechal safety shutter protects the user to IP4X/IPXXD – the live contacts are inaccessible behind this closed shutter.
Marechal Electric plug and socket system combines a crimped braid with a spiral-shaped spring guaranteeing highest performance levels – the flexibility of the crimped braid enables the tips of the Marechal female contact to remain in perfect alignment with the tip of the male contact without affecting performance.
The spiral spring provides comfort for use as the force applied to create the electrical connection functions with a small fraction of its elasticity.
Marechal butt contacts with silver-nickel tips guarantee exceptional electrical connections in high current, high temperature and hazardous area installations – conductivity is optimal with pressure applied contacts.
Marechal plug contacts are anti-corrosive providing high resistance to corrosion in industrial applications with excellent mechanical (IK08) and climatic shock resistance (-40°C to +60°C under operation conditions).
Marechal plugs guarantee the permanent absorption and tolerance to repeat electrical power overloads – T&D can provide expert technical support and technical specification recommendations for providing power to electric motors, generation sets, pumps and the associated high starting current requirements.
Marechal plugs feature glass-reinforced polyester (GRP) or metal casings according to the Decontactor model – the material choice contributes to the plugs and sockets excellent mechanical strength, long life expectancy and suitability for all industrial and hazardous area power installations.
Marechal 230/400V (3P+N+E dual-voltage) sockets are designed to receive four-phase and three-phase 400V plugs and single-phase 230V plugs. This compatibility constitutes a significant saving for the user when installing Marechal sockets.
- modular plug-socket system to suit a maximum number of different combinations
Marechal provides maximum versatility – by combining 2 products (inlet or socket-outlet) and 3 assembly accessories (wall box, inclined sleeve, handle), 6 additional products can be obtained.
- Improving Control : Pilot Auxiliary Contacts
This option provides feedback to the Centralised Management System (CMS) on the ON/OFF position of the socket outlet – with the capability to transmit information, such as the temperatures originating from an isothermal probe.
For harsh power distribution applications (high induction, high direct current intensities and Zone 1/2 hazardous areas), the contacts can control a contactor.
Keying Of Marechal Plugs & Sockets
Keying is associated with positions on the Marechal electrical plugs and sockets – it differentiates each plug and socket through the machining one of the notches, or «notching», 24 different types of electrical current, which is determined by the voltage/frequency pair.
The line colours provided in the Marechal general catalogue also match the relevant international standards. They appear on the ring and voltage label on the base of the connector, thus enabling the frequency/voltage pair assigned to the appliance to be easily identified – 24 keying positions are available.
Most of them match an assigned operating voltage. Others remain free to meet other voltage requirements or to create specific and customised versions.
