Electrical connectivity EX ATEX

A first step towards creating an inter­national standard for industrial plugs and receptacles was taken with the IEC 60309 and CEE Publication 17, “Requirements for Plugs and Receptacles for Industrial Use”. “IEC” stands for “INTERNATIONAL ELECTRICAL COMMISSION”.

When selecting plugs and receptacles from the existing ranges for standardization, preference was given to round plugs and receptacles, as the contact-making insert can be arranged in various positions (hours of day). This allows a high degree of differentiation of plugs and receptacles with regard to the various types of currents, voltages, frequencies, etc.

GHG 51 Ex-Plugs and Receptacles 10 – 125 A

Providing electrical energy there, where it is most needed – even in hazardous areas for the Zones 1, 2, 21 and 22. Non-stationary electrical apparatus have generally high requirements on the energy/power supply. Robust plugs and receptacles as well as a high chemical resistance are at the first glance very important. Electrical reliability is a must not only for all connectivity products.

GHG 51 Ex-Wall Socket with RCD/MCB

The new explosion-protected wall sockets with integrated protective device allow the local, customized protection of the connected equipment.Especially in industrial environments with their numerous sources of danger, the protection of persons always comes first. Here, an RCD/MCB that is connected directly upstream from the end consumers is the optimal solution. With a tripping current of 10 - 500 mA, it provides safe protection against serious injuries due to an electric shock in the event of a fault of the connected equipment. With the built-in RCD/MCB, the feed line and the end unit can be protected individually to suit the required load.

Light Metal Ex-Plugs and Sockets

The explosion-protected light metal plugs and receptacle devices can be used in the areas of Zone 1 and Zone 2 at no risk of explosion. Extremely harsh conditions of use in the hazardous area requires the devices to have highest mechanical strength. The explosion-protected CEAG plug and socket devices can be used to supply the appropriate energy to portable electrical equipment in these harsh conditions. The robust plug and receptacle devices with high-quality cast aluminium housings can be connected to a large connecting room via explosion-proof conduits or explosion-proof screwed connections.

Plugs and Receptacles Plastic Version

CEAG plugs and receptacles are not only robust, they are also very reliable. In the “normal” indus­trial environment plugs and receptacles are exposed to similar conditions (chemical and mechanical) as their explosion-protected counter­parts. With the introduction of the plug and receptacle generation Crouse-Hinds has now a complete program for industrial usage.

Ex-Repair and Maintenance Receptacles 16 A up to 63 A

For maintenance, repair and upgrading work, appliances such as drills, welding transformers, hand grinders and such are needed but are not in accordance to the explosion-protection regulations. To be able to use these appliances in the Zone 1, Zone 2, Zone 21 or Zone 22 explosion-protected areas a hot work permit has to be issued. For the duration of the repair or maintenance work, the environment has to be free of all explosive hazardous atmospheres.

Ex-Repair and Maintenance Receptacle Distribution 40 A and 80 A

For maintenance, repair and upgrading work, appliances such as drills, welding transformers, hand grinders and such are needed but are not in accordance to the explosion-protection regulations. To be able to use these appliances in the Zone 1 or Zone 2 explosion-protected areas a hot work permit has to be issued. For the duration of the repair or maintenance work, the environment has to be free of all explosive hazardous atmospheres.

Ex-Portable Multi-Outlet Distributions and Cable Reels

Electrical equipment, such as pumps, scales, etc. can be used flexibly in areas of Zone 1 and Zone 2 that are at risk of explosions, they can be safely supplied with energy by means of portable CEAG multi-outlet distribution units or cable reels. The multi-outlet distribution units are equipped with flange-mounting socket outlets that even comply with the high degree of protection IP66 when they are plugged in. This means that this distribution units are also suitable for use in the harshest industrial conditions.

Ex-Protected Portable Power Supply Units

Special requirements apply for power distributions for the use and operation of portable equipment in hazardous areas in Zones 1, 2, 21 and 22. It is necessary to ensure that any external mechanical influences are effectively kept away from the equipment. CEAG explosion-protected power distributions fulfil these high mechanical explosion protection requirements by means of a high-strength protective framework made of stainless steel (1.4301) and enclosures that have been specially developed for this purpose.

Fl-Ex Power Cords

Non-stationary electrical apparatus have generally high requirements on the energy/power supply. Robust plugs and receptacles as well as a high chemical resistance are at the first glance very important. Electrical reliability is a must not only for all connectivity products. A high safety standard, a steady hold and faultless contacting even under vibration or the effects of an aggressive atmospheric environment are the basis for a secure and reliable utilisation. CEAG plugs and receptacles offer more, apart from the proven technology, this product series is defined by its innovative details. For example, the very efficient cable strain relief or the new coding system of the various versions offers different solutions for a secure and problem free utilization in all areas.

eXLink – Ethernet/USB

The inlets and receptacles eXLink Ethernet and eXLink USB extend the proven connector series eXLink for hazardous areas. They can be used for plug-in connection for industrial LAN/Ethernet and USB applications with each other in areas with an explosion hazard. The normally used electrical isolation of an intrin­sically safe interface is no longer necessary. The Ex-de technology of the connectors allows the use of full industrial Ethernet power without barriers. This increases the efficiency of the bus architecture and reduces the sus­ceptibility to faults and therefore the costs.
