• 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.

Hazardous Area ATEX Plugs & Socket-Outlets for Refineries, Chemical And Pharmaceutical Industries

• By Chris Dodds : estimated reading time 4 minutes

Marechal plugs and sockets are ATEX certified for use in potentially explosive environments including Zone 1 and Zone 2 hazardous area applications.

Marechal plugs and sockets are compact and have an automatic watertight sealing for electrical installations – up to IP66/67 and compact panel or wall mounted designs are available for low voltage power distribution in hazardous areas.

Hazardous area Applications

• Electrical power connectors for buildings certified within ATEX zones
• Mounting of electrical connectors on conveyors, sorting machines, ventilation systems and mobile equipment (exhausters)
• ATEX power outlets for mobile pumps, mixers and heating systems in hazardous areas

Marechal ATEX Certified Plugs & sockets

Ex Certification

Marechal’s plugs and sockets as well as socket-outlet boxes and junction boxes are certified in compliance the ATEX 2014/34/EU Directive and are also IECEx certified for use in Zone 1 and Zone 2 (Gases) & Zone 21 and Zone 22 (Dusts).

Proven Safety In Harsh Operating Conditions

Marechal’s ATEX plugs and sockets have a compact housing and are designed with personal safety in mind with quick release which automatically isolates the power to eliminate the risk of arcing.

Quality & Reliability

Designed to be long lasting and reliable, Marechal’s ATEX plugs and sockets have spring-loaded butt contacts to maintain a reliable electrical connection and the contacts are tipped with silver-nickel to provide resistance against corrosion.

Water & Dust Tight Sealing

Marechal plugs and sockets are automatically watertight (IP66/IP67) when the plug is inserted into socket allowing the plug and socket to be resistance against steam-cleaning, water jets and chemicals and eliminating the need to turn a sealing ring.

Optional Auxillary Contacts

Most Marechal plugs and sockets have optional auxiliary contacts allowing for the connection of thermistor, control or signal with ease.

Optional Mechanical Locking

Marechal ATEX plugs and sockets also offer an optional locking systems to prevent accidental power supply to a machine during maintenance

Trace Heating Systems & Heat Trace Cables

The heat trace cable ranges stocked and supplied by Thorne & Derrick International includes electric heating cables for process temperature maintenance, pipe and vessel freeze protection and roof and gutter de-icing applications where snow and ice removal is required – cables and systems are available for commercial, industrial safe area (non-hazardous area) and hazardous area heating applications with ATEX certification.

Electric heat tracing is a cable based system used to maintain, raise temperature and protect process pipework and vessels against freezing temperatures and associated frost damage – heat tracing cables mitigate and counteract cold weather effects as part of a Winterization strategy for industrial and process applications against low (sub-zero) ambient temperatures on both onshore and offshore locations.

Heat tracing systems utilising self-regulating, constant wattage and mineral insulated (MI) heating cables are available to provide the optimum electrical heating system for your application – we provide a trace heating system design service.
