Product list Potentially explosive applications
Intrinsically safe and pressure-encapsulated protective devices ensure reliable signals in the Ex area.
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
Potentially explosive 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.
Products for protecting potentially explosive applications
These products enable you to protect your potentially explosive systems against surge voltages.
TERMITRAB complete for Ex applications
The surge protective devices for the intrinsically safe area are available in different voltage and circuit versions. TTC-6…-EX is available in both a pluggable and a one-piece design, each with screw connection.
PLUGTRAB PT-IQ
The PLUGTRAB PT-IQ product range provides pluggable surge protection with multi-stage, intelligent function monitoring of all voltage-limiting components. PLUGTRAB PT-IQ is available in a variety of voltage and circuit versions. The surge protection system consisting of supply and remote signaling module as well as the individual protective devices is available with Push-in and screw connection technology.
PLUGTRAB PT
With an overall width of 17.5 mm, PLUGTRAB PT is a range of pluggable surge protective devices for a variety of voltage and circuit versions. The protective plugs are tested with the CHECKMASTER 2. The PLUGTRAB PT product range is available with screw connection technology.
LINETRAB
The LINETRAB product range provides surge protection on an overall width of 6.2 mm. This allows you to protect up to four signal wires for digital or analog interfaces, including in intrinsically safe areas. Multi-conductor temperature measurements can also be performed via an optional DIN rail connector. LINETRAB is available with screw connection technology.
SURGETRAB S-PT
The SURGETRAB surge protective devices can be screwed directly onto field devices such as measuring elements. Product versions for parallel and through wiring are available. Various voltage and circuit versions are available with different connecting threads. SURGETRAB is available for Ex areas with type of protection Ex i (intrinsically safe) and Ex d (pressure-tight encapsulated).
