Motor & Pump Connectors

Marechal disconnectable motor switches (AC-3) for motors, pumps and highly inductive loads.

* 40-125A, 7.5-45kW, 690V a.c.
* IP66/67 water and dust tight
* Metal casing IK09 shock resistant

Applications : Pumps, motors and highly inductive loads - production lines and test benches for motors, fans, conveyors, mixers and containers. Marechal decontactors reduce downtime compared to hard-wiring.

DB3 Switch  - 40A, 7.5KW
DB6 Switch  - 75A, 22KW
DB9 Switch  - 125A, 45KW



30A to 250A, up to IP66/67

Marechal DS plugs and sockets (decontactors) are used to supply electric pumps and motors for water treatment and purification applications.

Applications : Connect mobile power to motors, submersible pumps, machines and mixers enabling workers to safely make and break electrical connections under full load.

  • IK08 IK09 shock resistant
  • Marechal DN20C and DN9C : IP54/IP55 water and dust-tight
  • Marechal PN7C and DSN7C3 : IP66/IP67 water and dust-tight
GRP or metal cased plugs are chemical and corrosion resistant, -40 °C to +60 °C.



20A to 63A, up to IP66/67

Marechal DSN plug and socket outlets (decontactors) provide switch rated assemblies for reduced machine downtime and improved plant production.

Applications : abbatoirs, cheese plants, bottling plants, breweries and distilleries.

IP66/67 watertight and with socket-outlet safety shutter providing IP4X protection. No hard-wiring.

Decontactors - Marechal DN     High Temperature Plugs & Sockets

20A to 150A

The first industrial plug and socket-outlet equipped with an integral switching device, Marechal DN is still the perfect heavy-duty solution: resists mechanical shock (IK09), overloads, heat and chemicals.


Heavy industry power supply to conveyors, motors, networks, crushers and machines - mines, quarries, steel, iron, power stations.


30A, 500V to 240 °C

PN plugs and socket-outlets provide automatic IP66/67 watertightness - spring-assisted terminals prevent loose conductors caused by vibration, thermal cycling and conductor creep. Fit them and forget them!

Applications : Iron, steel, electric ovens and motors.






Marechal Hazardous Area Plugs, Sockets, Decontactors Zones 1 & 2 (ATEX) - Oil, Gas & Petrochem

Marechal DXN plug and socket outlets (decontactors) comply with ATEX hazardous area certification for use in explosive atmospheres including Zones 1 and 2 (gas) and Zones 21 and 22 (dust).

Marechal DXN ATEX certified hazardous area plugs and sockets are rated from 20-63amps, IP66/67 watertight ingress protection and with socket-outlet safety shutter providing IP4X protection - DXN plugs and sockets comply with EN 50018 (explosion proof safety "d") EN 50019 (increased safety "e"), EN 50281-1-1 (electrical equipment for use in flammable dust atmospheres) and IEC 60309-1 (plugs and socket-outlets for industrial purposes) standards.
