Marking
The explosion-protected equipment
must be marked in such a way as to
guarantee that it is used correctly according
to its safety characteristics. The marking of
equipment is described in harmonized
standard IEC/EN 60079. Terminal blocks
with protection type “increased safety”
must be appropriately marked.
Phoenix Contact offers an extensive
range of Ex-approved connection
technology for process engineering. As a
result of the high-quality contact and
insulation materials, these terminal blocks
are particularly suitable for rough,
potentially explosive industrial applications.
The terminal blocks from Phoenix Contact
which have been approved for the
potentially explosive area are mainly
standard terminal blocks. In addition to the
usual approvals and according to standard
IEC/EN 60079-7, they also have an IECEx
and ATEX certificate from one of the EU-
authorized testing centers (DEKRA, PTB,
SEE, etc.).
It
is therefore not necessary with
terminal blocks from Phoenix Contact to
differentiate between Ex and non-Ex terminal
blocks in the warehouse. The advantages are
clear.
Protection type Ex e
The terminal blocks on the website
listed below meet the requirements for
protection type “Increased safety” Ex e
when the installation instructions are taken
into consideration. The terminal blocks are
therefore approved for installation in zone 2
and in zone 1 in particular, i.e., in the actual
Ex area. The latter, however, only on
condition that the terminal blocks are
installed in connection boxes which are also
approved for protection type Ex e and have
at least IP54 protection.
The available Ex e approved terminal
blocks can be divided into the following
groups:
– Screw connection terminal blocks
– Spring-cage connection terminal blocks
– Push-in connection terminal blocks
– Fast connection terminal blocks
– Miniature terminal blocks
– Terminal blocks for specialized
applications
Protection type Ex i
No special approval is required for
terminal blocks in applications with
protection type Ex i “intrinsic safety”. In
addition to Ex e-approved terminal blocks,
standard terminal blocks can be used here
as well. The increased requirements for
clearances and creepage distances:
