• Suitable for all explosion groups and use Ex
zones 1/21 and 2/22
• Free ignition sparks with lightning current up
to kA
• Tested according Class for high loads
• Screws protected against self-loosening
• Made from corrosion-resistant material (stainless
steel)
• Manufacturer and article labelling permanently at-

Equipotential busbar for zone 1/21 and 2/22 PAS
The PAS equipotential busbar (equipotential bus-
bar for potentially explosive areas) used for light-
ning protection equipotential bonding according to
IEC 62305-3 and protective/functional equipotential
bonding according DIN VDE 0100 Part 410/540. Secure
equipotential bonding connections against self-loosen-
ing according IEC 60079-14 and the Technical
Rules for Operating Safety (TRBS) 2152 Part 3.
Thanks the patented design, the equipotential bus-
bar can used system according IEC 60079-
14 and IEC/EN 62305-3 the zones 1/21 and Ex
zones 2/22. Big-Bag sacking,

Supplementary Sheet (IEC 62305-3) requires that
connections lightning protection systems poten-
tially explosive areas are created such way that
no ignitable sparks are created when the lightning cur-
rent passes through.
The lack ignition sparks explosive atmosphere
has been tested according IEC/EN 62561-1 ac-
cording the most demanding explosion group, IIC,
with potentially explosive gas mixture and lightning
current kA. The PAS represents the current state
of the art for equipotential busbars areas.3 Solutions
Equipotential bonding systems
Systems potentially explosive areas require equipo-
tential bonding according IEC 60079-14.
The PAS equipotential busbar tested according
to IEC/EN 62561-1 Class for high loads and is
suitable for indoor and outdoor applications
