Non-sparking equipotential bonding bars

The basis for safe system operation in potentially explosive areas

Equipotential bonding systems forms the basis for safe system operation.
To eliminate potential differences and prevent dangerous touch voltages, all electrically conductive parts must be connected to the equipotential bonding.

Lightning currents are particularly dangerous in hazardous areas.
To ensure that employees and facilities remain safe, the operator is obliged to provide protection in this area.

 

Non-sparking - tested with lightning currents

You can use the new PAS EX equipotential bonding bars in zones 1/21 and 2/22. They work in a non-sparking manner and their connections are secured against self-loosening.

 

Good to know:

  • The absence of ignition sparking in case of lightning current was tested in a gas atmosphere in cooperation with an external test laboratory.
  • PAS EX can also be used in applications with hydrogen.

Absolute versatility in every detail

This is what the new equipotential bonding bar for hazardous areas has to offer:

1 - Flexible connection possibilities:
Equipotential bonding bar in stainless steel (V2A) in two versions (long with 11 and short with 7 connections)

2 - Flat conductor connection
Defined cable routing for flat conductor connection with 30 or 40 mm

3 - Round conductor connection
Connection of round conductors up to 10 mm in diameter using an adapter

4 - Cable lug connection
M10 connection hole with thread for easy installation of conductors of up to 95 mm²

5 - Push-in connection
Connection of flexible and rigid conductors without tools (4-16°mm2)

6 - Cover with connection marking
For easy identification of the connections

7 - Universal use
In Ex zones 1/21 and 2/22

8 - Tested solution
Non-sparking up to 100 kA (10/350 µs) of lightning current and 50 Hz short-circuit currents

Advantages for you

Flexible use and diverse connection options in zones 1/21 and 2/22

  • More safety in hazardous areas

    The bars can be used in Ex zones 1/21 and 2/22 All connections are secured against self-loosening by means of spring washers.

    Totally flexible.
    Flexibly configurable with a multitude of connection options.

    Tested solution
    Non-sparking up to 100 kA (10/350 µs) of lightning current and 50 Hz short-circuit current.

    Tested in a gas atmosphere (explosion group IIC/hydrogen).

  • Cable lug connection

    Thread in provided in the connection hole, spring washer secures against self-loosening.

    Advantage:
    Schneller, easier connection WITHOUT additional nut.

  • Push-in connection

    Connection of flexible and rigid conductors up to 16 mm2.

    Advantage: Installed quickly and easily without tools.

  • Flat and round conductor connection

    Connection of flat conductors (30 or 40 mm) and round conductors (up to Ø 10 mm) possible with adapter.

    Advantage:
    Adapters ensure a defined, non-sparking contact between conductor and equipotential bonding bar by preventing conductors and terminal screws from touching.
