For years, facility managers have had to deal with the frustration of having to use 20mm "equipment" fuses in their desk power bars rather than proper BS1362 fuses. Frustration because they are both inappropriate for electrical mains protection and also pretty superfluous when we have a BS1362 fuse in all our UK plug tops. It is the recommendation of best practice, BS6396 that proliferates the use of individually fused sockets. It would not be the first time we have suggested that the legacy designs used by most of our competitors has more to do with commercial self-interest than safety!

However, we are not likely to have the standard re-drafted, so we have another solution. eLink from Burland complies with BS6396 without fuses!  Instead, we have used CBE switch breakers which function as both switch and circuit breaker.  These are able to be reset by the user saving time and effort. From a safety perspective, it is not possible to insert over rated fuses or worse still, metallic objects which have in the past led to fires!

Another first is our high power dual USB charger that not only can charge two iPads consecutively, but also has been adapted to work with Blackberry smart phones, something many others do not!

The PSE EX 16 family has been extended to include the PSE EX 19 and PSE EX 22 mounting diameter. Furthermore, the certification of the PSE EX was enhanced and expanded. The PSE EX family is approved for use in potentially explosive atmospheres containing air and gases. Further application areas also include industrial sectors such as mills, where solids are found in smallest form as dust, which may be prone to self-ignition.

Flammable substances such as gases, vapors or mist which are released into the environment, e.g. while in production, during transportation or storage, may ignite and pose serious consequences for persons and property. The same is true for dust which may develop in conjunction with air to an explosive atmosphere. To ensure security in these areas, the Device Directives 94/9/EC was developed for products and protection systems. The purpose of the guidelines is the protection of personnel and devices which are working in such hazardous areas. This is done by eliminating all possible sources of fire and ignitions in the products and systems used in these areas.

The PSE EX family is certified according to ATEX and IECEx regulations. The area of application is consistent with that of the device group II (other areas than mining). It comprises systems with a potentially explosive atmosphere consisting of a mixture of air and gases, vapors or mists or in industrial areas where dust-air blends infuse the atmosphere and the danger of a dust explosion can arise.

The approval marking is Ex II 2 GD (according ATEX regulations), Ex ib IIC T6 ... T5 Gb and Ex ib IIIC T85 ° C ... T100 ° C Db (according IEC regulations) for gases and dust. The temperature class was extended from T4 to T5 and T6. Therefore the permissible power dissipation of the PSE EX was limited accordingly so that the piezo switch is intrinsically safe according to EN60079-11. In addition, the flammability group was increased from IIB to IC, respectively IIIC (gas, dust). This extension will allow the use of the PSE EX in atmosphere with further type of gases, combustible dust, ignitable fibers and flyings.

Typical applications include oil and gas exploration rigs, petrochemical facilities, environments of transportation and storage of combustible materials, paint mixing devices, painting devices, grain mills, wood processing industry, chemical plants etc.

The PSE EX standard models are available with mounting diameters of 16, 19 and 22 mm with pin connectors and housing colors in red, green or natural aluminum. On request other colors, housing diameters and connection versions are obtainable. The switches for hazardous use have a label with the particulars of the certification and an identification number. Installation instructions are included in the packaging according to the ATEX directives.

Technical data / Approvals:
- PSE EX 24V, 40 mA, PT6 = 0.7 W, PT5 = 0.96 W
- ATEX II 2 G D
- IEC Ex ib IIC T6…T5 Gb
- IEC Ex ib IIIC T85°C…T100°C Db
