Specific ambient conditions place special requirements on surge protection. Surge protective devices for potentially explosive applications provide the right protection for ensuring maximum availability in sensitive areas.

Your advantages

  • Space-saving installation with the narrowest protective devices
  • Versatile use: designs and connection technology adapted to the application
  • Easy testing, thanks to pluggable version of surge protective devices
  • Worldwide use in potentially explosive areas, thanks to ATEX and IECEx approvals

TERMITRAB complete for Ex applications

The chemical and petrochemical industries involve industrial processes which produce explosive atmospheres. They are caused, for example, by gases, fumes or vapors. Explosive atmospheres can also occur, however, in mills, silos, sugar and fodder factories due to the dust present there.

The surge protective devices for the Ex area are subject to specific conditions. The products thereby meet the specific requirements for the intrinsic safety type of protection. Since all surge protective devices are assigned to the “Ex ia” category for intrinsically safe circuits, they provide maximum safety. In this category, the equipment must not be capable of causing an ignition, even in the event of two independent faults.

It can be installed in Ex Zone 1, Ex Zone 2 or in the non-Ex area. The connected signals can be forwarded through to Ex Zone 0. Some products also meet the requirements of the pressure-tight encapsulation type of protection. Approvals are granted according to ATEX and IECEx.
