Marking systems
The marker mounting channel is arranged
in the centre of the terminal to prevent
connected conductors from obscuring the
markings. Marking can take place with
Weidmüller dekafix and newly developed
ZS hinged marker systems. The hinged
marker is designed for up to eight-digit
marking and is simply snap-fitted
stripwise into the marking channel and
placed over the cross-connection
channels. Identification of functional
groups can take place with ZGB group
tag carriers.
Cross-connection system
Rational wiring is possible with two to ten-
pole ZQV, completely shock-hazard
protected units, no small partitions or end
cover plates for adjacent cross-
connections are necessary. Up to forty
connection points can be applied to a
potential with only one cross-connection
unit. The cross-connections can be
loaded with the rated current of the
corresponding cross-section. By breaking
out individual or several contact elements,
several terminals can be skipped to suit
the particular application. For control-
circuit terminals with two connection
points, two parallel cross-connection
channels are available. This enables two
potentials to be routed within the terminal.
Only in the case of these two applications
does the rated voltage reduce from 800 V
to 400 V. By means of prefitted adapters
from the W series to the screwless
Z series, combined use of both families
on one mounting rail is possible.
Connection of the WDU 16 or WDU 35,
the connection is realised with the ZQW 2.
The generous terminal
aperture size (test with
gauge pin according to
IEC 947-1) results in
space and cost
advantages, since the
rated cross-section is
connectable with ferrules.
With the ZPE protective
conductor terminal, efficient
contact to the mounting rail is
established by simply
snap-fitting the spring-loaded
metal foot. The one-piece
construction of the metal parts
enables lateral movement of
the terminal without
damaging the PE contact.
ZTR disconnect test
terminals
feature integral test
sockets for PS 2.3 test
plugs. The easy to
operate disconnect lever
clearly shows the
disconnected or closed
position. Feed-through
terminals and disconnect
terminals as such can be
cross connected.
