• By Chris Dodds : estimated reading time 4 minutes

Marechal plugs and sockets meet the demanding requirements inherent to underground and surface mine and quarry operations – robust enough to withstand exposure to harsh and hazardous area conditions including dust, mud and humidity.

Marechal plugs and sockets provide safe and reliable power connections at every step of the electrical control and distribution process.

mining Applications

• Power supply mining generators, motor signal and control, electrical enclosures and junction boxes
• Extraction saws, cutters, shearers, loaders and conveyors
• Processing crushers, grinders, sieves, screens and pumps

Power plugs for mining

sAFE & hAZARDOUS AREAS

Watertight & Robust Decontactors

Marechal plugs and sockets are constructed with robust materials with a proven butt contact technology ensuring that connections are sturdy and durable allowing control signals to be transmitted without the risk of corrosion.

Marechal’s plugs are resistant to spikes of up to 8-10 times rated current for continued operation during motor start-ups and have a built-in load-breaking capacity.

Additionally, plugs and sockets are watertight, certified to IP66/IP67 and with a shock resistance rating of IK08/IK10.

Flexibility Electrical Safety

Marechal plugs have an integrated power switch allowing users to quickly and safely connect and disconnect electric motors on load, shortening maintenance and repair time and minimising downtime, facilitating both preventive and corrective maintenance, reducing costs.

Compliant with the latest regulations including IEC EN 60947-3 for switches, IEC EN 60309-1 and the EU Low Voltage Directive.

ATEX Certification For Hazardous Areas

Marechal manufacture plugs and sockets for explosive atmospheres in accordance with ATEX Directive 2014/34/EU and used in Zones 1 and Zones 2 (gas) and Zone 21 and Zone 22 (dust), including the DXN ATEX plug and sockets.

Marechal plugs and sockets are waterproof, designed to withstand airborne and permanent humidity found within the food and beverage industry.

In the food and beverage industry electrical safety is critical where plant and machinery is subject to daily deep cleaning, high pressure water spray and steam cleaning.

Electrical power plugs and installations must be protected from water and dust ingress, impact shock and resist microbiological contamination in hazardous area applications.

Electrical safety

Live Disconnect Plugs

Decontactor = Plug + Socket + Motor Load Make/Break Switch

Marechal plugs & sockets can be disconnected under full load for planned maintenance or rapid change out of equipment during plant shutdowns without need for separate isolators and associated hard-wiring.

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 & Sockets For The Food & Beverage Industry

Marechal plugs and sockets are designed to suit all food and beverage industry applications and are fitted with a built-in switching function called a Decontactor which allows the plug and socket to be connected and disconnected with ease, under load, and without risk of electrocution to workers.

power plug Applications

• Electrical connection of mobile pumps and water jet hoses
• Connecting conveyors, cutting machines (slicers, mincers) and local control stations
• Electrical power supply to production machines, mixers, packaging units, fans, tanks
• Silos and bulk storage vessels (eg grain stores with Zone 21/22 explosive dust atmospheres)

Marechal DSN Plugs & Sockets

The Solution to your power requirements

Marechal DSN plugs and sockets are specified throughout the food processing and production industry for low voltage power distribution with current ratings 20A-63A.

DSN plugs provide IP66/67/69 ingress protection for resistance to intensive and deep cleaning associated with pressure power washing of food hygiene areas, including CIP (Cleaning in Place).

IK08 Shock Resistant Plugs

Marechal DSN plug and sockets provide unequalled strength over time and and have an impact resistant GRP casing providing IK08 shock resistance and protection against mechanical impacts up to 5 joules, guaranteeing robust, fast and safe operation during maintenance work – compliant with the IEC EN 60309-1 standard and the European Low Voltage Directive.

DSN range of plugs and sockets are watertight, robust, resistant to chemicals and steam cleaning – ideal for all your food plant safety needs, allowing your production facilities to be as efficient as possible without risk of unplanned downtime caused by sub-standard specification plugs and sockets.

Chemical Resistance

Marechal plugs and sockets are manufactured from highest quality advanced materials with excellent resistance to aggressive chemicals, cleaning solutions, saline solutions, diluted acids, hydrocarbons, mineral oils and alcoholic substances for use in highly corrosive atmospheres.

For humid & corrosive environments – steam cleaning

Silver-nickel butt contacts resist corrosion even after years of operation and the automatic socket seal resists steam cleaning, water jetting and corrosive chemicals and detergents.

Simple operation in fatty or humid environments

Even if wearing protective gloves the operator can simply press the release button to eject the plug and a quarter turn removes the now “dead” plug from its socket. For extra safety in-line connections are also switched off.

Daily shutdown and machine mobility

Acts as local isolation, padlocking available ON/OFF.

Robust requirements

The glassfibre-reinforced (GRP) casings protect against mechanical damage up to 5 joules (IK08) and have an operating temperature of -40°C and +60°C.

ATEX Certification For Hazardous Areas

Marechal also manufacture plugs and sockets for explosive atmospheres in accordance with ATEX Directive 2014/34/EU and used in Zones 1 and 2 (gas) and Zone 21 and Zone 22 (dust) including the DXN ATEX plug and sockets.
