Explosion-proof watertight electrical connectors
MARECHAL’s DXN Self-ejecting is designed to enhance the safety of electrical installations in hazardous areas
This new and unique ejection system for zones 1/2 (gas), and zones 21/22 (dust) on the market, is certified according to the ATEX 94/9/CE directive and IECEx standards, and complies with all current safety and security regulations for the protection of equipment and personnel.
MARECHAL ELECTRIC has developed the explosion-proof DXN DECONTACTOR™ range of compact and watertight connectors as part of its mission to provide safe electrical installations for use in hazardous areas.
Rated for operation up to 63A, DXN units combine a new mechanical self-ejecting mechanism with MARECHAL’s unique patented DECONTACTOR™ integrated load-break switch. This unique solution is currently used on lifeboats that operate from offshore oil rigs. It can also be used for applications such as mobile containers, cranes, electrical boats, truck hook-ups or any portable equipment.
Connecting the DXN self-ejecting socket-outlet by direct insertion ensures users are provided with the same features as standard DXN ranges. The new DXN decontactors are available in three different versions: standard plugs and connectors, self-ejecting plugs and self-ejecting coupler sockets.
Permanent safety
In terms of unique features, the two new self-ejecting systems have been designed to protect equipment from accidental or forcible disconnection and full load. The systems also protect equipment from being moved whilst connected.
Whether connected or disconnected, both types of self-ejecting DXN decontactors can be operated by any authorised person, under any circumstances and often without the need for a Hot Work Permit.
Mounted on top of the self-ejecting explosion-proof connector, a “shark’s fin” latch is used to lift the ‘hook’ from the base and disconnect the plug from the socket. The force required to operate this system is comparable to the force required to disconnect a plug from the socket of a standard DXN connection manually. This operation immediately releases the plug every time tension is detected on the cable.
The shark’s fin hook, which is mounted on the base of the plug, is connected by a tension cord to the power cable. Pulling on this cord activates the shark’s fin hook to release the plug. Both systems are rated as standard ranges for operation at a maximum up to 750-V.
