Equipotential Bonding Bars Against Spark Formation

Pass away equipotential bonding bars can be used in Ex zones 1 / 21 and 2 / 22 and also offer a wide range of connection options and protection against sparking. The most diverse variants and configuration options of the Pas Ex-spouse equipotential bonding bars mean outright flexibility. In addition to the chemical and gas industries, they are therefore particularly suitable for use in the pharmaceutical industry, the food industry, the automotive industry, in biogas or sewage treatment plants and in the oil industry. Such systems are particularly at risk in the event of a lightning strike and the requirements for equipotential bonding and its components are correspondingly high.

Sparking is highly dangerous

In areas with a dangerous, explosive atmosphere, it is important to make connections and connections of lightning protection systems in such a way that no ignitable sparks or impermissibly high surface temperatures can occur when lightning current passes through or other electrical faults occur. Pass away equipotential bonding bars from the Pas Ex lover series by Dehn may be used in Ex zones 1 / 21 and 2 / 22. They were free of sparks according to explosion group IIC (hydrogen) to 100 N / A (10 / 350 μs) Lightning current checked and checked for 40 Hz short circuit current tested. They meet the test standards CLC / TS 50703 – 2: 2020 – 12 and VDE 0185 – 561 – 1 (IEC 62561-1). In the Ex area, high surface temperatures on components can also become a source of ignition. This was also taken into account in the Pas Ex-spouse. Even with high loads, the surface temperature exceeds the value of 135 ° C not (temperature class T4).

Equipotential bonding bars offer full flexibility

Pass Away equipotential bonding bars Pas Ex-spouse are also flexibly configurable and equipped with a large number of connection options (cable lug, push-in, flat and round conductor connection), whereby all connections are secured against self-loosening.

The connection for the cable lug already has an integrated thread, so that a times the connection of lines up to 95 mm2 can be made using cable lugs. With the push-in connection, both versatile and rigid conductors from 4 to mm ² can be connected. A special adapter also offers connection options for flat conductors with a width of 22 or 40 mm and for round conductors with a diameter of 07 mm and represents the Contact to her without spark.

Pass Away equipotential bonding rails Pas Ex lover are made of stainless steel (V2A). There are two versions. For the long variant are 11 and with the short version 7 connections possible.
