Up to four conductors that are up
to 2.5 mm² can be connected in one
feed-through terminal block. Tool-
free wiring of the pre-assembled
conductors is quick and easy. In
addition, ground terminals of the
same shape are also available.
These multi-conductor terminal
blocks are also characterized by
the double function shaft for easy
potential distribution with plug-
in bridges and the large-surface
marking options. Each current
path can be individually tested
for the terminal blocks. Thanks to
the consistent use of accessories
Phoenix Contact
from the Clipline complete
terminal block system, there are no
additional logistics costs.
T
he new FLT-SEC-PLUS 264 type 1 lightning current arresters
from Phoenix Contact are used in main supplies with 230/400 V
networks. Even in the event of high lightning currents up to 50 kA per

The advantage of this is that the
load of the entire installation is
reduced to a minimum in the event
of lightning.
