Potentially explosive areas ATEX zones 21
and 22
The unique PAS equipotential busbar (equipoten-
tial busbar for potentially explosive areas) used for
lightning protection equipotential bonding according
to IEC 62305-3 and protective/functional equipotential
bonding according DIN VDE 0100 Part 410/540. Unique.
The PAS (equipotential busbar for potentially ex-
plosive areas) offers the following advantages:
• Free ignition sparks
• Tested independent testing body kA
• Explosion groups IIC, IIB and IIA

Thanks its patented design, the equipotential bus-
bar can used for installation according IEC
60079-14 and IEC 62305-3 the zones 1/21 and
Ex zones 2/22.
According TRBS 2152 Part and IEC 62305-3, the
arresting paths the lightning must created in
such way that heating ignitable sparks spray
sparks cannot become the ignition source the po-
tentially explosive atmosphere. confirmed that the PAS
type equipotential busbars are suitable for use po-
tentially explosive areas Zone 1/2 (gases, vapours,
mist) well Zone 21/22 (dusts). The PAS equi-
potential busbars not have their own potential igni-
tion source and are thus not subject the European
Directive 2014/34/EU.TBS

PAS equipotential busbar for potentially explosive areas
Innovative.3 Potentially explosive areas
Systems potentially explosive areas require equipo-
tential bonding according IEC 60079-14. All the
bodies electrically conductive parts must con-
nected the equipotential bonding system.1. Secure
equipotential bonding connections against self-loosen-
ing according IEC 60079-14 and the Technical
Rules for Operating Safety (TRBS) 2152 Part 3. Patented.

The lack ignition sparks explosive atmosphere
has been tested the basis IEC 62561-1 accord-
ing explosion group IIC and can thus also used
for the explosion group IIA and IIB.2
