Parallel connectors for ex applications

It is becoming more and more common to install ring equipotential bonding conductors in the hazardous areas of industrial plants.

This parallel connector Cu/gal Sn is specially for connecting electrical equipment and closing the ring equipotential bonding.

It has been tested to be non-sparking up to the designated residual current. On installation it is fitted with a spring washer under the nut to prevent self-loosening (in accordance with the requirements in DIN EN 62305-3 Supplement 2).

Tested as suitable for use in potentially explosive atmospheres

  • Ex zone 1/2 (gases and explosion group IIC) and
  • Ex zone 21/22 (dust)


This parallel connector does not possess any potential source of ignition (mechanical device) and as such does not fall under the European Ex directive 2014/34/EU.

It is therefore suitable for unlimited application in potentially explosive atmospheres.
