Product Description
Power Terminal Block
The XRAPLCESK power
terminal block has the same
shape as the relay modules
and is used to feed in the
bridging potentials. The
nominal current is 32 A.
When the total current is less
than or equal to 6 A, supply
can take place directly at the
connecting terminal blocks of
one of the connected relays.
End Cover
The XRAATPBK end cover
is required at the start and
stop of a relay strip. It can
also be used for visual
separation of groups of
relays as well as separating
relays with voltages greater
than 250 V and separating
neighboring bridges with
different potentials. It is
equipped with pre-scored
break out points at the
bridging positions so that
individual bridges can be
passed through as needed.
It may also be necessary to
use the end cover between
adjacent relays when three
phases (L1, L2, L3) are
used on the contact side
of the relay.
Bridges
The XRAFBST colored,
insulated plug-in bridge
system reduces wiring
time by up to 70% compared
to conventionally wired
relays. The XRAFBST2,
2-position bridges, are
suited for bridging a smaller
number of relays and total
currents
<
6 A. When a circuit
is supplied from both sides,
the circuit can be opened at
any point, allowing all other
modules to continue being
supplied at the same time.
The XRAFBST500 allow up
to 80 modules to be bridged
at one time. If bridges with
different potentials meet in
neighboring modules, the
end cover XRAATPBK
should be used. All bridges
are equipped with a groove
for removal with a standard
screwdriver.

Power Terminal Block
Note
1
The separating plate, XRAPLCESK, should be installed for voltages greater than 250 V
(L1, L2, L3) between identical terminal points of adjacent modules. Potential bridging is
then possible with the XRAFBST bridge system.
