The new XR Series relays include products
designed to meet high continuous current
and/or long electrical service life
applications. The XR Series relays are plugin interfaces that connect to basic terminal
blocks that use screw connection
technology. Overall width is 14 mm (0.55").
These relays are best suited for applications
that require higher continuous load currents
than miniature relays can carry and switch.
They can withstand inrush currents or brief
overloads without damage, and allow for
continuous load currents of up to 10 A. The
XR Series Relay boasts an average service
life of the contacts that is two or three times
the normal life of a less powerful relay,
resulting in service cost savings.

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 250V 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 plugin
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 < 6A. 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.

1 The separating plate, XRAPLCESK,
should be installed for voltages greater than
250V (L1, L2, L3) between identical terminal
points of adjacent modules. Potential
bridging is then possible with the XRAFBST
bridge system.
2 The current rating for the normally open
contact (#14) is 10 A. The current rating for
the normally closed contact (#12) is 6 A and
can be increased to 10 A by bridging the two
#12 contact connections.
