Marechal PN7C Plugs – 7 Contacts 25A 500V IP66/67 Multi-Contact Connectors

Marechal PN7C Plugs – 7 Contacts 25A 500V IP66/67 Multi-Contact Connectors

Marechal PN7C plugs and sockets are compact and watertight and have a rated current of 25A, a maximum voltage of 500V and up to 7 contacts. PN7C plugs and sockets are automatically IP66/IP67 when connected and the socket outlet itself is also watertight when the lid is closed.

PN7C connectors form part of the Marechal range of signal and control plugs – multicontact connectors (5 to 37) with waterproof electrical sockets to IP66/IP67 and IK08 IK09 protection for electrical equipment against external mechanical impacts.

Marechal PN7C Plugs - Install & Operation Guidelines

Marechal PN7C Plugs – Install & Operation Guidelines

  • Remove an adequate length of cable outer sheath according to the accessory used.
  • Strip conductor insulation of the indicated length (see Table T1).
  • For inlets, affix the CE sticker either on the handle or on the box, or near the inlet if semi-flush mounted.
  • Insert the colour-coded rings between the inlet/plug top or socket-outlet and its rear accessory.
  • The two protrusions of the rings must be positioned on the hinge side for the socket-outlet/connector and on the catch side for the plug/appliance inlet. These rings act as seals.


  • The socket-outlet is shielded by a protective lid held in the closed position by a latch. Depress the latch to release the lid.
  • To be connected, the Marechal PN7C plug and the socket-outlet must have similar ratings (voltage, current …), and compatible contact configurations.
  • To connect, align the plug bayonets with the hollow parts of the socket-outlet (if any, use the two red marks as a visual indication), push the plug in and turn anticlockwise: the circuit is closed.
  • To disconnect, push the plug and turn it clockwise to withdraw it. Close the lid. See Figure F1.
